I visited the Techs at my local Chevy dealership today. They had two Duramaxes in with serious problems. I have taken some photos and posted them on Yahoo for those interested. The first two photos are of an 03 or 04 LBS with a burned up/broke turbo. It has a bent shaft, destroyed impeller, bad seals and oil all through the intake/exhaust system. The third photo is of what a good turbo looks like. It would run when the guy brought it in but you should have seen the smoke.


The rest of the photos are of an engine that has a serious problem yet to be determined. It is a 04 LB7 with 12K miles. The guy that owns the truck went to a lot of trouble to make it look stock before calling the wrecker. He removed his pillar mounted gauges and what ever chip he might have been running. The 4" exhaust was still in place. The Tech tried to do a compression check on the RH bank. All cylinders were at 120 PSI and there were some mechanical noises while testing. When I got there the engine was on the stand and the Tech was working to remove the head. When they removed the rocker cover there were loose and broken valve train parts everywhere. One of my photos shows some small flat pieces that set across two valves. You will notice some are broken. There is a picture of a bent push rod. It is one of the better ones. 3/4 of them are bent really bad. They did a cylinder leak down test on the other head while I was there. Two of the four were at 30% + , one at 20%, one at 10% and one at 9%. I didn't ask what the RH head was. There are a couple pictures of the exhaust side of the turbo. It looks like it had water go through it. At this point they don't know what caused the bent and broken parts. The valves and the top of the pistons in the RH head look fine. The gears on the front are in tack also. Interesting ordeal. I stayed around as long as possible talking to the Techs and shooting pictures. This one wouldn't start when towed in. It smelled like something other than diesel was in the tank but it was not gas. I don't know if I will get more photos. The Tech will be off the rest of the week and I am leaving Sunday on vacation up north. I will post what ever I hear when I get back. Later! Frank

Frank,


Your link wants me to sign in?

Sorry Zeeb. It defaults like this every time. I will go back and open it up. Thanks. Frank

Zeeb, try it know and let me know if it works please? Later! Frank

Looks like that motor reved to the moon, great photos.

Frank,


As Tim noted, the link works now.


Nice to see an old school dealership, it takes a pass from Ashcroft to get into the service area where I bought mine...http://www.dieselplace.com/forum/smileys/Confused.gif


Thanks for the pics.

Maybe the owner cleaned his air filter with gasoline!

I am in real tight with the Techs even though I didn't buy my truck from this dealership. (Murdocks in Tremonton) They couldn't get me one. Back when the Dmax was a baby I helped them with some info I got off the Diesel Page. The Tech asked me today if any of the chips removed the rev limiter. I told him I didn't know but would post a question. Later! Frank Edited by: Frank Blum

Not likely either motor was stock as you described. One fellow at Muncie showed me pics of Dmax piston rods bent up big time. When I asked him about certain aftermarket injection he said yes and I don't believe it was propane or nitrous.

I guess what I'm saying is it's interesting to see how and what breaks but anybody considering stock or slightly modified Dmaxs has nothing to worry about. They take a good hard lickin and keep on tickin... literally.

Great pics Frank!


Thanks!

Two of the four were at 30% + , one at 20%, one at 10% and one at 9%.


Hell no wonder they are having problems figuring out what`s wrong. They think that engine has 5 cylinders on one sidehttp://www.dieselplace.com/forum/smileys/Dead.gif

You have over 400 post, been here sense the beginning, and you don't know about the rev limiter? Or do you mean using a chip and not through programing?


I do believe you need programing, something like the Stealth, and maybe the programming in the Attitude. (But am not sure about the Attitude doing it)

I can't get link to work ....





Mac

I can't either.

I wanna see the link too!!!http://www.dieselplace.com/forum/smileys/Cry.gif

Mike, this is the new 04 V-10 Duramax. He had one reading written down and I watched him do all four on the left bank. His question to me was: Do any of the after market chips/programs raise the rev limiter. I know some do but I don't follow this part of the forum very close. Wait until you get 60! http://www.dieselplace.com/forum/smileys/Big Smile.gif Later! Frank


PS: Yahoo must be having problems. I can't go there either. We need to call Al Gore to fix it.

The DieselPlace prolly made it crash with all the hits ....





Mac http://www.dieselplace.com/forum/smileys/Shocked.gif

I cant see the pics but I have two theories based on above info.


Turbo failure could have likely been caused by the no. 4 cam bearing spinning, the oil to the turbo is fed via that port and if the bearings spins, no oil to the turbo


Second one, I am guessing a shot of Ether. These motors will run 45-4800 rpm with out damage if not sustained. Ether will cause the motor to overrev and runaway.


Of course, these are just my thoughts... no idea for sure what could have caused either failure.

Eric, the story I heard, which was about third hand, was the engine did run away for over 5 seconds before it was shut down or quit on it's own. With 3/4 of the push rods off the rockers I would say it quit on it's own. They are both a mess. I will try to get more details tomorrow. I will mention the cam bearing to the Tech. Can that be checked without tearing the engine apart. There was oil all through the intake system. The Tech did talk to the GM tech people about the second engine. They also told him it might have been given a shot of ether. I saw a guy blow the head right off a little 4 cylinder Buda using ether when I was in the Navy. Later! Frank

Oil in the intake, motor reved extremely high.... hmmmm


Is it possible that an oil seal in the turbo let go and flooded the motor with engine oil and let it runaway?


I had it happen to a skip loader of mine, you couldn't shut the motor off until it exploded, traced it to a faulty oil seal in the turbo.

I had problems with his URL as well.


I ended up getting it to work using this URL.

2 different engines . . . first one had the blown turbo and oil in the intake. Second one is the over-rev . . . wasn't caused by oil. I think GM owes owner #1 a fix, but owner #2 is probably (and should be) S.O.L.. Even owner #1 might have chipped the turbo to death, but it seems unlikely.Edited by: Colorado Kid

I see in one of the pics that the wastegate line is plugged with a bolt? Is that on dissasembly or????http://www.dieselplace.com/forum/smileys/Confused.gif

The 2 pistons on the left show where the valves would be. Did they actually touch, or is this just some kind of phenomenon?

(Tried to post the picture, but I wasn't able to get it to work)Edited by: GSXRTURBO1

Someone here had the fuel filter up on the engine and was using two pieces of metal just like the one in the picture. Could it be someone here?

Maybe because it is Frank`s truck! Sorryhttp://www.dieselplace.com/forum/smileys/Cry.gifEdited by: hdmax

Hmph. Alot of those pics, I had no idea what I was lookin at. Didn't see any real damage. Be glad I don't repair YOUR vehicles.http://www.dieselplace.com/forum/smileys/Big Smile.gif http://www.dieselplace.com/forum/smileys/Big Smile.gif

hdmax, do you have a question or problem with the prototype bracket photo? The production one looks like the photo below. Later! Frank

No I do not have a problem, or question. I seen the pictures while looking at the blown engines and for a minute thought maybe one of the guys here was the one with the problem.


It was after I made the post,when I realized it was pictures of your truck that I was looking at, and not the bad engine.

Mike, this is the new 04 V-10 Duramax. http://www.dieselplace.com/forum/smileys/Big Smile.gif Later! Frank


Is that a special order engine? http://www.dieselplace.com/forum/smileys/Wink.gif

I'm sure it is, but I here it's only avaliable with the H3 suspention upgrade http://www.dieselplace.com/forum/smileys/Big Smile.gif http://www.dieselplace.com/forum/smileys/Big Smile.gif

Hoot, it is a very special order. That was the first thing I though of when Mike said it had five cylinders on one bank.


I went back in today to see if the engine that over reved had been torn all the way down. It wasn't. The Techs seem to thing Eric and GM are right about the ether. The owner said: I changed the oil and started it. It sounded like it was running wide open. I turned of the key but it ran for several seconds more before it quit. The fuel filter looked like it had been changed. Hard to say what really happen. Could be he couldn't get it started after changing the fuel filter and used ether in it. The dealership is going to repair it under warranty. I have reposted the photos under a new link. Hope all will be able to see them this time. Later! Frank


PS: Eric, the waste gate was plugged when the truck came in.

Frank, Now I am almost positive that Ether was the death


Interesting that the waste gate was plugged.. Is that on the turbo damaged engine?

The plugged lines are on the one that over reved. I sure would like to know what the guy was doing to cause the problem. There is a lot of plumbing between the filter and the cylinder. If someone was cranking and someone spraying they were making a bomb. Later! Frank
