Ok I had an 01' ecsb come in the other day pouring oil out of the crank vent. checked the balance rates with EFI and I got none of the balances were correct except one injector (-2). So i got Pensacola diesel to send me a set of remans and the install kit. I also bead blasted and cleaned the injector lines, flushed the fuel rails out and changed the fuel filter. Two days later the truck comes back with fuel in the crank case again! did the balance test again and everything check out fine there. So I tore into it thinking I didnt torque something down right (which I have forgotten to do once.) Re-torqued everything to specs re-assembled, changed the oil and drove it for about 20 miles. got back to the shop and pulled the dip stick only to find........... DIESEL IN THE OIL AGAIN!!!! Any idea guys?

Do some research on Pensacola. I'm pretty sure they sell a lot of shitty remans. Tons of people have has problems with their injectors

Awesome so I'm probably going to have to eat the 1700$ For the set I bought from them. They dont offer a waranty either do they? I knew 1700$ had to be to good to be true..... I usually buy the remans through another shop here in town for about 2000 ish. Guess I should've stuck with them.

looking at this --> "I also bead blasted and cleaned the injector lines" i'm betting another problem is your lines wont seal now. the abrasion from the blaster is just enough to cause them not to seal down well. a buddy of mine tried and got the same outcome.

get new lines from merchant auto - they have injectors too

that and you have pensacola injectors - dont use them EVER again

bead blasting the lines is fine as long as you use glass bead, its actually how gm tells you to clean them, there is a information bulletin on it out there somewere from gm

If the lines were leaking the o-ring on the injector should keep most of it from going into the oil and you should see a pretty decent fuel leak. If not then chances are its an injector.

Most times it is a leaking return line seal, but with Pensacola injectors, it very well could be a cracked injector.

The best way to tell for sure (And locate which injector it is), is to remove the valve covers, hook up the fuel lines and run the engine with the valve covers removed.- Then look for the leak.

It was bad injectors and to top it all off the solenoids on three of them weren't working correctly resulting in no pilot injection and a loud engine....

I just ordered some remans 2 days ago. Glad they were not from Pensacola diesel!
