Hello,


I am considering purchasing a 94 Silverado 4x4 with 6.5L turbo diesel, and would like to know what to look out for. Are there any common problems with these? Is it a good, great or mediocre powerplant?


Thanks,


Al

How many miles? History? Modifications or bone stock? L56 or L65?


The 6.5L is an economical turbo diesel. It can be had at a reasonable price and will give good service if maintained properly.


I would think a '94 should cost no more than $3,000-5,000 in good shape.

Welcome, The only MAJOR problems for the 6.5L is the PMD or for gas guys it would be almost an ignition control module, which there are many many fixes for the problem.

If by winner, you mean an engine that is poorly designed that needs constant maintenance, then yes it is a winner. I honestly do not understand why people on this board defend this power plant. The only advantage to the 6.5TD is the price. It is very cheap compared to other diesels. However the fact of the matter is, the good old Chevy 350 will get just about the same mileage, pull the same load, and will certainly provide you with many more trouble free miles than the 6.5TD ever will.

I only wish people were more honest with about the 6.5 TD before I bought my ’95 Suburban. The problem is, I love my Suburban, I love the idea of owning a diesel powered Suburban, but I hate having to constantly repair it.
I had a vehicle inspection done on this thing before I bought it. The shop gave it a clean bill of health. One month later, I replaced the Serpentine Belt, OPS, Lift Pump, AC clutch switch, AC Relay, and horn relay. A week later the AC compressor froze up on my, and now my AC is toast. One week after that, it blew a head gasket in a major way. Who knows, the block and most likely the head may even be cracked. I will know for sure on Monday. I will get it fixed, and sell it.

My 6.5 gave me 30,000 miles of reliable service in under a year. I worked it hard with a GCVW usually around 12k lbs, going as high as 15k for distances of 800 miles or more at a time. Until the thing threw a rod on me at 173k (cause still unknown, motor has to be disassembled and inspected further), it never let me down. Never had any PMD issues, even though I drove around with a spare in the glove box just in case. Maybe that's why it never died on me. http://www.dieselplace.com/forum/smileys/Big Smile.gif

The 6.5 is by far the best value out there price wise in terms of a diesel truck. It is also the most anemic, but it's still not that bad and I was satisfied with the acceleration. I had mine doing 0-60 in 9.5 seconds last winter, 12.5 in the summer. Is it a great powerplant? In my opinion it could be made to be a great powerplant with the kind of aftermarket support that the 350 and 454 receive. I'd personally place its quality between a gasser powerplant and some of the other diesels available. It's much better than a gasser (I'd like to see a 350 or 454 last as long as my 6.5 did with the kind of use I gave it), but probably not as good as a Cummins or 7.3 PowerStroke. But that's just my opinion from my year of ownership.

Juancho, except for the head gasket and OPS all the items you mention are standard items that would break on a 350 (or other brand truck) just as much. Fuel pumps die on 350s, so do serpentine belts, the A/C compressor style you have ALWAYS dies. My TRUCK always had some little item broken on it, but the MOTOR, transmission, and differential started every time I turned the key and got me and my load where I needed to go reliably... until it threw a rod. Old cars break. The reason I went to a Cummins this time around was because I decided I wanted a new truck so that I wouldn't have to deal with the hassles of an OLDER vehicle, as you have discovered happens, and I like the Cummins/Ram better than the Duramax/Silverado or the PowerStroke/F-250. The 6.5 is definitely not the best motor out there, but give it its dues.Edited by: tdupuis

I have miled out 2 of these trucks so far 350,000 kms on one and sold it for $8,000 when i was done, 350,000 kms on another and took out a head gasket because of my own stupidity while towing, once that truck is fixed i would trust it for another 100,000.


Yes these trucks don't seem to have alot of power but with the money you've saved over buying a D'max or F**D or DOG (sorry tdupuis) you can probably invest it in the 6.5 and have an even better truck! Once i've completed my mods i will not be afraid to pull against those trucks at all.

Maybe the 9 year old truck you bought was neglected by the former owner. Maybe it was overheated a few times like they do on the pre 97's when towing. This is all info that is well known on this board and any other. Maybe your mechanic ripped you off, maybe he knew the former owner who knows. Sell it and move on to another old truck and expect many trouble free miles or just fix the weakness found in your current truck and be happy with it. I understand how you don't want to keep it after the let downs but to sell it now after dropping all the money into it to fix it is wastfull. At this point I would pull the motor and drop in a complete reman from Avant Salvage and drive it. I think if one head pops the other will soon follow and the cost to swap out the gaskets and possible cracked heads you will be at the drop in motor price.
I have a 98 and am at 100,000 miles. I replaced the oil pressure switch, a coolan

Funny, the Mustangs that I've left in the dust didn't think it was such a dog... If you think it's such a dog I'll gladly go up against you in a highway pull with trailer attached. http://www.dieselplace.com/forum/smileys/Big Smile.gif I'm not here to attack the 6.5, my experience with it was a good one.

I defected when my 6.5 blew up because for my personaal circumstances, it made the most sense to buy a new truck and I haven't been impressed with the Duramax or the PS, but I have been impressed with the Cummins. If my circumstances were different, I wouldn't have hesitated to put a new 6.5 in my old truck and driven it for another however many miles. So overall I would say if the price is good and the truck seems good, go for it. Just don't be surprised when things break. This is what we call wear and tear. http://www.dieselplace.com/forum/smileys/Big Smile.gif

Just wait til you try to buy part for the dodge, Without that non dodge engine (I believe cummins is Ford owned )


And just ask a Ford owner, whos honest with you, about that international engine they call the POwerStroke. They too have problems, Head gasket, coolant eating holes in the block etc .....


Yes the 6.5 has issues BUT so does everything else out there that is mechanical, even the airplanes the fly overhead or fight to keep us free, I put over 350,000 miles on a 6.2 long before 6.5 came around. the only difference between the 2 was the turbo and the electrioic pump.


Besides do you really need to pull a 40,000 lb stock trailer 80 mph ?


BESIDES I'd own a Chevy even if it had the old 6.2 N/A or a Gas drinking Gasser

The "Cummins" powerplant that Dodge uses, if you want to get technical about it, is not made my Cummins either, but rather by Consolidated Diesel Corp. (CDC). Just about everybody owns a piece of them, including Ford and Cummins.

I wasn't attacking just pointing out that everything has problems, no matter how high tech. Sorry if you misunderstook that as an attack. I sold part for a few years and I saw all engines give their owners trouble at one time or another.

The 6BT(5.9L) engine has got to be hands down THE most reliable, efficient, and powerful diesel engine ever produced. Its used in trucks, generators, tractors you name it, and it does a hell of a job. But to be completely fair about all this, we have to compare the fuel system as well as the engine itself to make a comparison. Stanadyne's DS pumps have problems alright, but the old Bosch VE pumps had their share as well, the VP44 in the electronic 24v versions is also problematic, not to mention pricey. The ones running with the Bosch 'P' pump on the other hand, how can you knock that? The pump is a derated version of the one used on the big brother to the 6BT, the 6CT(8.3L), That motor/pump combination will easily outlast several Dodge trucks.

SORRY TDG but I believe I would put a Benz diesel engine up against about any other out there But they are hard to find them in pickup trucks, Oh course their are groups of Cat owners that think theirs is king, just that truck is to big for my garage door.

Are you refering to International Diesel ltd?





Bowtie,


I own a '96 Ford F-250 Powerstroke, and I can tell you with absolute certainty that the International 444 engine is far superior in every single way to the GM 6.5TD. Also, from what I have read, the Cummins 5.9 will eat the 6.5TD for lunch. In fact, it can also eat the International 444 for an appetizer.


Comparing purpose built diesels, and GM's attempt to make a diesel out of a gasser is comparing Apples to Oranges.

Hm, what is it that makes these engines so much different from each other?

This thread reads as if the 6.5 is the most inferior of the available diesels. But things break or fail on other engines, too, and when buying a used car that's 6--7 years old, be it a truck or a passenger car, you have to prepared for doing the repairs.

It took more than a year to get mine fully functional, but I expected that before I bought it. I'm planning to drive it at least another 5 or 6 years, and it will have about 500kkm on it then. If it still runs fine by that time, I'll probably keep it.

I wouldn't attempt anything like that with any other truck or SUV available here. They just don't last that long.

Try looking at the 1994 ford engine, The 6.5 easily keeps up or leaves the other two behind. The 6.5 factory support advancement stopped around 1995 because of the pump/PMD/FSD issues. As far as the Cummins eating a PS NOPE don't happen either sorry, The PS is an amazing powerplant as is the cummins.


And if you are referring the a attempt to make a diesel from a gasser that stopped with the 5.7, which BTW I have seen them run over 500,000 miles untouch also. The 6.2 and 6.5 were designed and built to be diesel, detriot designed.


All my early comments were pointing out ( go read them) were that ALL engine have problems, and ALL Trucks have problems, it might be the dodge transmissions or the ford head gasket/h pin holes in the block, find me a motor out there today that hasn't had some growing pains. I believe if GM had not had to, for what ever reason, spend so much time fixing something that should have been an easy fix..ie... PMD problem that the 6.5 would have been a much nicer powerplant and had more aftermarket support for it.


OH BTW I never had any Powerstroke big talkers connect the other end of that chain that i threw them to their trucks aganist my 6.2 burban. And I was the only Diesel in all the mud bogging comp's I entered, and all the Alaskan trail ride my 4wd club went on, oh which it always came home under it's own power to. Been playing with diesel in many different ways for a while now and enjoied them all.

The 6.5L might be designed to be a diesel but I see the chevy SB when I look at it, it even has the same firing order. This is an easy truck to work on, but it requires faithful service and an understanding of it's limitations/problems. All that said, I would buy another.

It's a light duty diesel... true sense of the word. Good service when not overloaded. Good drivability characteristics. I always enjoyed the throttle response and the distict clatter. I put 80,000 miles on one and can't say I remember a time that I felt it wasn't a good motor.

09-19-2004, 02:22 PM
In defense of the 6.5, it is still in production to this day, and I expect it to be for some time to come. Stanadyne has already manufactured a new DS4 pump, the 5827, for their applications. I would like to try and use some of the upgrades they made to these pumps on my own, especially the DE derived Heavy Duty Fuel Solenoid and new cam ring.

i went to an ODOT (ohio department of transportation) vehicle auction the other day. thought about biddin on a couple 6.5's, dont have the money. there were two 93 one ton, 2wd, with a dump bed. nice lookin trucks with real good state service records. i would definately buy another 6.5 in the future.

WOW,


Thanks for all the replies, I currently have a 1984 Motorhome with a ford 6.9L N/A diesel, which is the predecessor of the 7.3, and I am VERY happy with it. I have never been a Ford only, or Dodge only, or Chevy only, closed minded truck owner, but it doesn't sound good from you guys for this 6.5. As some have said stuff breaks, and all the A/C stuff doesn't mean anything to the diesel motor, but, allot of unhappy folks here.


The 94 Truck I am looking at only has 90K, and is 4WD, but they are asking $7,000, and I am not so interested anymore.

I bought my 6.5 in June 1996 and it had 200 miles wwhen I took got it from the dealer. It now has 171,000 miles on it. The bigest 6.5 pain has been the PMD/FSD which should be recalled! (IMNSHO) I'm not IP # 2 first one chainge out by the dealer on GM's dime at 23,000 miles. Other than the PMD the other pain stuff has had nothing to do with the 6.5TD like the latest was the multi function switch (turn signal, CC, wipper) these were a problem with all Chevy C/K Pickup per a dealer Tech who has changed out a couple hundred of these over the years. The A/C problems are not Diesel related it really isn't fair to lay those things at the 6.5TD. If I had to replace my truck now I would try and find another 6.5TD mostly because I know and understand them. Any time you buy a used vehical you run the risk of it being neglected unless you know the vehical and even then things go wrong. How many horor stories have we heard form people who have bought gasers?

My 95 6.5TD gets about 20mpg, and it's very comfortable to drive. My 2004.5 Dodge Cummins 600 gets about 13mpg... (only 12,000km)


I have pulled my forklift on my tandem axle trailer with both..(10,000+lbs) No comparison. Obviously the Cummins pulls better. However it did cost close to $50,000 (CDN) taxes in.


My 95 is an economical truck. Diesel is $.72 per litre up here, Gas is about $.90 I put about 1000km a week on my 95.


I also owned a 2001 silverado crew 4x4 6.0L gasser. It got about 14MPG... and had piston slap... Dan

I guess its my turn. I bought my truck in 1997 from George Strait. (He got it free from GM for making the commercials he used to do) It had 10,000 miles on it it. (They gave him a new one) I now have 256,000 miles on it. I replaced the IP once at 230,000 A couple alternators a couple A/C compressors (we use a/c here 350 days a year)


I farm &amp; ranch for a living. I pull trailers with everything from cattle to combines on them, I drive in the pasture thru brush,sand, and mud daily. I also play steel guitar on the weekends all over Texas.


In my mind I have never found a truck that can do all of this with the comfort, economy, safety, room, dependability that my truck has givin me.


It is not the most powerful diesel out there. It overheats when you work it, its hard to start when its cold, it spits fuel all over during refuling, nobody can work on it, the 4 wheel drive takes too long to engage, it doesnt turn sharp enough, and it is a pain to get to the oil filter.


With that said would I buy another one? have i gotten excellent value for my money? would i recomend it to others?


Hell yes.http://www.dieselplace.com/forum/smileys/Hug.gif

Once again, Thanks to everyone for their educated opinions.


The truck I was interested in sold to someone else on ebay for $5800, probably a pretty good deal, but since I did not get the chance to go look at it and drive it, I wasn't comfortable to go that high.

Turbine Doc,


Sorry man, no slam intendedhttp://www.dieselplace.com/forum/smileys/Approve.gif. I'm just not a half ton guy anymore. I'm not knocking the three I have had (or the one my wife still has), though, because they never let me down. I just feel much more confidant when carrying a heavy load for the braking ability of a heavier chassis truck. I just figure that no matter the chassis weight, with the right gears the mileage will still be good.


I also realize, though, that it costs less to replace chassis parts on a lighter chassis. -just have to take the good with the bad, I suppose.

Ah there is the rub( Snow no offense taken-good place to insert jab/humor), if towing heavy loads regularly I'm in agreement with you; kinda like big blocks no substitute for displacement, or in towing for mass, I will say that my 1/2 T isn't stock 1/2T either, I upgraded brakes &amp; suspension as much as possible without swap to 3/4 or 1T (pending mod), and have 3100lb rated wheels now also.

It's a small big block.

JUST MY EXPERIENCE, and many others--abuse the truck/engine, and it is guarenteed to fail. With that said, ANY engine/drivetrain will give out if it's abused. Now that I have a new engine in my truck (6.5 TD), I LOVE it. There are still the problems of having any older truck. Mine's 11 years old. The engine was replaced at 210,000 miles, and NOT because the block was shot, but because the heads and/or gaskets were gone. Prior to me buying it, the guy said that there was no major work ever done to it, and he was constantly pulling horse trailers with it. I could have paid a shop about $2400 to replace the heads or paid a buddy of mine $2700 to put a REMAN Longblock in it with a warrenty...not much to decide on that deal.


There was a time that I had my mind made up that I'd never again spend the money on a LD Diesel engine. Since then, with the proper care and maintenance of the vehicle, I LOVE it, and would again buy a 6.5, after checking it out a little better. I'm new to diesels, but the 6.5 has more power, and about 3x the fuel mileage that my last gasser had (DODGE RAM 360 CI.) The only problem I have now, is the ever problem causing PMD.
I'm about to relocate it with a PMD cooler, and a new PMD.


The 6.5 seems to me, a very economical vehicle, and with the right upgrades, a great source of power to the rear wheels. It's still no powerhouse, though. Not that I will ever need 700 RWHP.


Again, I love it. I dont think I would have paid $7000 for a 10 year old vehicle, PERIOD. Especally without knowing the extent of the abuse from the previous owner. This truck has everything I'm looking for right now. I have the power to tow the biggest boat/trailer that I'll ever own, and the fuel mileage of my wife's cavalier (well, almost.)

I am new to the 6.5TD. Bought a '98 Sierra 2500 2wd with 177,000kms on it. A clean truck with a 8 foot box and extended cab. Bought the truck and immediately had the classic Pump Mounted Driver failure symtoms. With this forum and another diesel forum I was able to diagnose the problem.


I had the used car dealer where I bought it do the remote mount Heath diesel relocate behind the front licence plate under the radiator. Truck has run awesome every since. No hitch on the truck when I bought it so it doesn't look like it has ever done any towing. I will be installing a tow hitch for landscaping trailer. Using 5W40 Valvoline synthetic for the winter and have changed the fuel filter so far.


My experience with diesels is limited to VW Jettas that have provided longlife with economy. I am looking for long service, economy and power from this diesel. I thought I had made a big mistake with this truck right after I bought it but like I said the remote PMD worked perfectly. (GM record shows the IP was changed at 106,000 kms)


How many miles can I reasonably expect to get out of this motor?


How long will the IP pump last with the PMD issue solved?


This truck will be heading North next fall for our annual Archery Moose hunt . Arrowed a 50" wide racked Bull approx. 1200 lbs with 1 arrow at 15 yards this year. Freezer is full.


Anyone else out there do any bow huntin? Can you answer my questions above?
