I have a 2004 gmc with the lb7. Replaced bad fuel filter housing and hooked up the fuel lines backwards after twenty mins of pumping it and spinning it over I realized something was wrong. Found out I swapped the fuel lines and it fires up but now it’s pushing oil and fuel mix out the dipstick. Could I have filled crankcase full when I had the lines backwards? Thanks for any help
Crankcase full of fuel

Would they just go bad after changing fuel filter housing? Never had this problem before I hooked lines up backwards
Yep, cracked infpjector body. Completely normal for lb7, get sac type injectors and it won't happen again...
Just had same issue with mine... it’s your injectors.
I bought mine from Lincoln diesel. Look for suggestions for places to buy them because if you are buying re mans you will want to get them from a reputable source. I bought all 8 brand new Bosch injectors, injector kit, and cat nictane filter adapter for just about 2k.
When I was shopping I heard to not specifically buy from Pensacola diesel. They offer a very good price, but apparently it’s a poor shop. I recommend Lincoln diesel

Lincoln will take care of you right. They sell Bosch. The only way to go is Bosch updated injectors.
