Have an lb7 had a few bad injectors was getting fuel in the oil so I replaced all 8injectors. Still had fuel in oil so did all new return lines. Still was getting fuel in oil so did 8 more injectors all new! With new return lines and ran truck with valve covers off to make sure return lines weren't leaking. Still getting fuel in oil. Pulled cp3 and put different one in and still getting fuel in the oil at a loss here. Any one have any more opinions?

I had this same exact thing happen to me. racked my brain for 2 weeks before I just took the sticks back out and sent them back to injectors direct. turns out when the mechanics at the shop I had do the work for me torqued the HP lines to the injectors they cracked the fitting that the HP line connects to (learned that life is easier if you just do everything yourself) Aaron was more than willing to replace the bad injector and I haven't had any problems since
