Good Duramax Story

[SCREAMNEAGLE]

My friend know a farmer that had a first generation truck that had 280k and decided he needed a new one. Well he said that he wasn't getting another Dodge. He used the old truck to pull an 50' two level hog trailer with it. Went through 4 transmissions. He decided he wanted a new Duramax. My friend, a die had Mopar nut, kept telling him he'd be sorry. Well he got the truck and was pulling and empty 30' trailer. In all of about a mile, the truck started loosing power, he looked in the rear view mirror and saw smoke billowing out from behind, and then the motor let go. We're taking crank, rods, block, just destroyed it. He got the truck pulled over and said there was fuel all over the place and left a trail behind him. Some how the motor filled with fuel and took the motor out. GM told him it would be at least two months before they would get a motor. The truck has 1500 miles on it.

Yikes... I feel bad for the guy...



Its also too bad for us...competition is a good thing.

A fuel leak into the crankcase could happen on any... Ford Dodge or GM.



GM should get him another truck... 2 months is WAY too long to go making payments on nothing.

The way I see it is that it is good punishement for him to be so "uneducated" (how's that for politically correct) and buy a Duramax (that name always reminds me of that DuraLube junk).



Hell, I even buy a Powersmoke before I'd own any diesel put in a Chevy from the factory.



Seriously though. Too bad for him. If it were me, if they told me two months before I got my 1500 mile old truck back, I get my $$$ back somehow, and tell the jokers at the Chevy dealer I was going down the street to buy a real Diesel

UMMmm - Mark, please explain how *I* might experience a similar fuel leak on MY '91 Cummins that would cause it to self destruct - while it is RUNNING... ?

The pump on your first gen truck has a driveshaft seal with low pressure fuel behind it. If that seal fails, it can leak fuel into the engine. Not that it's common at all, but any time where i used to work we had a pump out and do anything at all to it, it got a new driveshaft seal, to make sure nothing like that happened.



Although it is theoretically not possible, the supply pump, if defective, can also dump fuel into the crankcase. I know of no instances of that happening, but I have heard of the injection pump getting fuel into the oil.



If that seal begins leaking, it usually results in a hard start condition after the truck sits for a while rather than exploding the bottom end by diluting the oil.



But, like I said, it CAN happen.

"All this attention to detail will help ensure a completely finished product once these trucks reach the dealers. Any concern over the aluminum cylinder heads and other new technologies should be laid to rest. We ran these trucks harder than just about any owner might, and we failed to find any weak link in the engine or the new Allison 5-speed automatic transmission. "

As I always say: "Chevy, like a crock". Guess driving it down the road is more difficult than the GM engineers could imagine

Jeeze, how many engines "self destruct" when they're NOT running...

We have many big cam 350hp Cummins stationary generators at work. We were running one for about 8 hours one day and the seal on the nose of the injector pump let loose, filling the crank case with fuel. While the crank and rods did not try to ventilate the block, it did blow (about 40 feet) most of the oil out of the pan and spun the bearings quite nicely. Needless to say - it needed to be rebuilt..... What oil was left in the crank case was only tinting the fuel now in it black.

Thats the biggest killer of Locomotives too, Fuel contamination in the crankcase. Unfourtunatley, there is no way to know untill its usually too late unless you are constantly checing your oil. Luckily, in the 24 engines that is unlikley since we dont have oil int he injection pump.
