Hey guys, well i have no idea what is going on with my truck. It is an 02 CCSB duramax 4x4. We had it serviced like we do every time it is due at the dealership. Anyway it has a virbation at idle that is very noticeable and it smells like strong diesel fumes. At lunch today i was revving it up watching the exhaust for black smoke. I thought i had a bad tank of fuel. Anyway after work i came out and there is a big puddle of diesel fuel under the front of the truck. I looked and looked and cant see where it is coming from. Well coming home i was watching my oil pressure and it never got above 40 psi and was as low as 18 -20. What the hell is going on? Any help would be great guys. Oh it has 125,000 miles and the only mods are an exhaust and a PPE tuner. It stays on level 2 all the time. And the vibration goes away while driving but at every stop sign it is right back. thanks Charles

 

injector leak? I honestly have no isea about these new engines having only worked on Detroit 6/8 71's in my career but I would be looking by the injectors or pump for leaks. Bump for a better answer!

 

check your oil level,I think my friends had an injector issue and filled the crankcase with diesel

 

thanks, i will check that.

 

I was just going to say that, if your leaking diesel I would suspect the case is probably full of fuel.
I believe that year truck had an issue with the injectors. I wonder if that's the one that is now covered by a 200K mile warranty?

 

I talked to the dealer and it is covered. Im taking it in Monday morning.
