I'm a newbie here. First question type stuff.
01 Duramax with 132k, filled the oil pan with fuel. Obvious injector problem. Called GM and it was "sorry, you're 3 months over the warranty". From here, the short version is I got the injectors replaced, it started missing and blowing white smoke (smells like fuel) and throws codes for 4 injectors. Pulled it down and looked at everything again- replaced the copper seals and o-rings again.
Now the question- the copper seals don't look like they've been touched. The new ones are .079 thick- exactly the same as the old ones. Getting ready to pull it down again and send the new injectors out to get them checked. Any ideas on what's happening here? The injector cups are clean and look to be in perfect condition. None are pulled and seals intact.

Thanks in advance!!
Tim

ps- codes are P0300, P0305,P0307,P0306,P0308

 

where did you get your injectors from?

 

Injectors came from Pensacola Diesel. After I got them I saw a couple of threads here about guys having some problems. I have called them and they have offered to test them.

 

There is your problem, i had gone through 4 sets of their injectors last summer. they just don't work. send them back and get your refund. they will charge you a 10% restocking fee.

i eventually went to the dealer and got new ones from them, even at my price they still were expensive but totally worth it.
