Well truck has been running a little rough for a few weeks now. Did a balance check on my injectors with my Predator. Well at 25,000 miles I've got 3 bad injectors. Number 4 is the worst reading close to 8 at idle in drive and park. Two others are residing around the 5 mark.


Anyhow my appointment is on Monday. I'm not sure of the skills of my local diesel tech, but than again maybe Eric will chime in offering his services.


I'll keep everyone posted.

V R


how long you been runnin' the CAT secondary ? guess when they go, they just go.........

I had in on since around 8k. It'd been moved once, but other than that no issues.

Darn Rick sorry to hear this. Maybe you should send you injectors to Kennedy and juice them up a little. i don't know if they are completely rebuilt or what.


Hows everything else since the last time we spoke??


Jason

Jason,


New injectors from the dealer are free, juiced ones, well probably not. It's funny though two months ago I was kicking your butt around on Kennedy's dynohttp://www.dieselplace.com/forum/smileys/Embarrased.gif, now I need injectors, go figure.


As for me, just been real busy. I also have been avoiding the computer except for business purposes. I quit smoking around 2 months ago as well and trying to keep myself active.


Anyhow we'll have to get together one of these days for a cookout, maybe I'll even have to host a small SE WI GTG just to sit around and shoot the bull.

Do you regularly use an additive? If so, which one? 25,000 is really low miles. I wonder if it was defective from the start, and just now showing the signs.

I've used FPPF and Schaeffer's religiously.

Bummer Rick,


Hey, don't let them swap out your VRStraps for those whimpy stainless steel cables they are using for the recall.

As I stated before, I'm not overly concerned nor am I upset at this time except for the fact of not knowing the skills of my local mechanics. The last few new vehicles I've owned have been traded in at 60k or less so I never had any real issues to get to know them with.


As for my straps, I'm keeping them but I will likely take the freebie from GM when available. Should be good for hanging my address on the side of my house http://www.dieselplace.com/forum/smileys/Ermm.gif

It`s not like you can`t find Grand Rapidshttp://www.dieselplace.com/forum/smileys/Big Smile.gif


It`s that damn Juice I tell ys!http://www.dieselplace.com/forum/smileys/Big Smile.gif It is really the way you run it when John Kennedy installed the hot stuff last fall. Remember what the limp is?http://www.dieselplace.com/forum/smileys/Approve.gif


Good luck in getting this taken care of! And thanks again for a steller product. They are holding up great.


If it is at all possible to make another trip to Grand Rapids, I`d say you will have much better servicehttp://www.dieselplace.com/forum/smileys/Big Smile.gif That is what I plan on doing if ever in need of repair.

Rick, sorry to hear this! I assume you will get all 8 replaced?


Congrats and good luck on the quitting smoking. It will be the best thing in the long run for you and your family!


Keep in touch and good luck with everything!http://www.dieselplace.com/forum/smileys/Big Smile.gif SPICER

Mike,


I'd love for Dmaxallitech to do the repair and yes it would be worth the drive, but I think I remember him stating once that he was no longer allowed to do warranty repairs on Chevy's which is what I have(if I'm incorrect hopefully he'll chime in).


As for juicing, I own a pred, but never run tunes in it. I'm one of those guys who likes the power, but not for my daily driving, too much boost with this tuner.


Arlen,


I won't know much until next week when I have my appointment. The weirdest deal was they were in good shape and QUICKLY went south.


What's even funnier is that I checked them again this morning and my cold engine numbers are better than my warm engine numbers. Maybe it's not really the actual injector but some type of seal(s) has failed causing the rates to get nasty under heat and expansion???


As for the quitting smoking, been a little over 7 weeks since I lit one. Decided that why die early and make my wife rich? http://www.dieselplace.com/forum/smileys/Ermm.gifEdited by: Victory Red

I've used FPPF and Schaeffer's religiously.


Guess I`ve been right all along! http://www.dieselplace.com/forum/smileys/Clap.gif I have never used nor will I ever use fuel additives. I believe that they are more hype then help! And for the price it had better increase fuel mileage. Most of them add 10-30 cents pre gallon. (As if fuel wasn`t already high!http://www.dieselplace.com/forum/smileys/Cry.gif )

I was thinking it was your truck that JK put the hot Juice on, and moments later recieved a call about limping your tranny. I guess I am older then I thoughthttp://www.dieselplace.com/forum/smileys/Cry.gif

Sorry didnt see this one soon Rick, been busy at the hospital last couple of days. See if your truck will make it a few more weeks.. I see some very optimistic news on the horizon regarding me and Chevy's.....and still GMC's...http://www.dieselplace.com/forum/smileys/Clap.gif


Cant dispell much more then that at this time.....but if she will last a bit longer..... you might be in luck

Rick,


Did you do the check with your predator because you were having drivability issues or just out of curiosity and by chance find the injector problems?

Guess I must've jinxed it by looking at them when you were here. Kinda figured things may get to this point based on the readings.





If you can't get it done right, Orfordville WI is where I'd send you.

srode,


I actually checked them on a semi regular basis(mainly during PM time reason I bought the Predator is the diagnostics). However a few months ago when Forced Induction and I went to play on Kennedys dyno he saw an injector that was on the high side but dropped to a decent level after full warm up.


A few weeks ago I began to notice when I'd come to a stop my idle would be rough almost like a misfire but smooth out within 10-15 seconds. Some days it would be bad, other days not even noticeable. I don't see anymore smoke than usual, but I seldom hammered around town anyhow.


The weirdest thing is that I just changed the OEM filter(had the faint hope maybe it would help). When I cut the filter open, which had around 11,000 on it it was around 1/8' used and showed no signs of the banding that seems to be commonplace. I also noticed a little 'pool' of fuel inside the cap at my Schrader valve and that when pressurized will bubble at me.


I also recently developed the steering column thump but unlike my last truck this one only does it when I'm turning.


Needless to say I'm no mechanic. Sure I'd love to wait on Eric to do them but I'd really not rather take the chance of being hit with a breakdown at a most inopportune time. Plus I have plans to hit Custer SD and points west in July with my daughter. I promised her a camping/fishing trip(since her younger sister and mother won't do the camping thing). So the sooner I can get this repaired the sooner I see whether or not my local guy is skilled or not and not risk being 1000 miles away and stranded in nowhere.

You have the secondary fillter on you truck and still had injectors go bad. So I guess there nothing to all they hype about getting a 2nd filter.

Secondary filtration and an emulsifier. I just hit 25,000 using the same combo since about 15,000. I'm getting the feeling from these reports that this truck is a ticking injector time bomb!

I wouldn't lose faith in my truck or this powerplant. I for one have been very pleased in every regard to this point.


Also injector failure could be caused by things other than dirty fuel. There's a chance some other failure caused this issue. Once my truck is fixed it'll go back to the the same way I had it.

I've been wondering over the last months if there is any connection between additional filters and injector failure. I'd agree with some of the above posts that there does not appear to be any direct data saying that additional filters will prevent injector failure. I'm still planning to add a pre filter though. I still think cleaner fuel is one of the best things we can do for the DMAX. Even if there are design issues with the injectors, I'd still think clean fuel would benefit the pump assembly.

Sorry about your troubles Rick.

My 01 had 72,000 on it and never an injector problem although I may have had one on the way out towards the end of my ownership as I did have a strange knock.

I ran a post OEM fuel filter for probably 50,000 miles and also used additive. FPPF for a while than Primrose 405... I'm using Primrose on the Dodge now.

It's really ashamed that you have to always have this worry on the back of your mind. What happened to buying a diesel with the intention of keeping them for 200-300 thousand miles. I unloaded mine out of fear of out of warranty cash outlay. I figured if it would come to that I might as well put it into a new truck. With the Dodge I now have a 7/70 warranty on the truck and 7/100 on the diesel. Hopefully I can relax again for a while. These new diesels are going through growth pains for sure. I think GM dropped the ball AGAIN with fuel system problems. They came out of the 6.5TD injection pump fiasco looking like crap, leaving people stranded all over the place for years. Now GM is doing the same thing... dragging it out, without any real durabilty fix and possible future out of warranty repair costs that are frightening.
Fun to own for the short term but scary for the long term. I don't miss the worries.Edited by: hoot

Rick,

When you bring it in, complain of excessively hard starts. Mine are being changed next week. I'm also having my GMC worked on by the Chevy dealer across the street from the GMC dealer. They said all I had to do was sign on the service order where I refused to let the other dealer do the work, no questions asked.

Good Luck and thanks for a great product,

Pepperidge

p.s. did you ever contact La. Guard Dog?

Pepper,


I shouldn't have to complain too much full operating temp my number 4 will read as high as 9 these days. It's was above spec, but I suppose the more issues I have the quicker my resolution may come.


I did talk with La Guard Dog via e-mail once, but I got so busy they fell to the wayside for a while and I had forgotten all about them. Then with the recall announced I figured my product would have lost it's usefulness, but that was a poor assumption on my part.


Roegs, I still think dual filtration is the way to go. Why it didn't 'save me' I guess I'll never know unless I kept the injectors had it analyzed for failure and they could give me some definitive answers.


Hoot glad to see you still hanging around here and there. As for me my 100k warranty will run out about the same time as my payment book. At that point I'll have to see what's best to do.


Later tonight I'll have some real info from my dealer and what they plan to do.

Oh well no new news because my dealer cancelled my appointment. Now I'm a little PO'd. http://www.dieselplace.com/forum/smileys/Angry.gif Seems that to GM specs out a 4hr procedure to properly diagnose our injectors, or at least that's what I was told. I was also told it would be next monday at the earliest for them to schedule that time.


Anyhow I headed off to another local dealer that can get me in on thursday but they'll need the truck all day(it figures though, I have a half day on Wednesday but too soon for them to schedule me in)

Sorry to here about your bad luck VR! It really is too bad that you cann`t have Eric do the job.


Hope you can get it taken care of real soon.

Orfordville!





BTW, 60k on mine. About 30k with secondary filtration, all with FPPF, and 90% with semi clean source fuel.





These injectors will be sent out for testing to see how they act on a test stand.

I see some very optimistic news on the horizon regarding me and Chevy's.....and still GMC's...http://www.dieselplace.com/forum/smileys/Clap.gif


Cant dispell much more then that at this time





Now that is the absolute best news I've heard in quite awhile! http://www.dieselplace.com/forum/smileys/Clap.gif

Count me in as a "Bowtie" who's happy to hear that, Eric! I'm still "just around the corner" in Ohio and turned 82,000 miles this week!http://www.dieselplace.com/forum/smileys/Clap.gif

Does this pertain to warranty work only?


What I mean is; Are you currently allowed to work on non-warranty work Chevy trucks? IE: Beef up my tranny when the time comes!http://www.dieselplace.com/forum/smileys/Big Smile.gif I hope so! Because, I don`t know if I would let anyone else do it.http://www.dieselplace.com/forum/smileys/Clap.gif
