I've posted a lot about my problems with fuel in my oil, things done so far new injectors from merchant auto, new cp3, new injector lines. I've changed my oil a lot here lately and I'm just paranoid now my oil pressure will start out around 35 on a hot day but after a few thousand miles on the oil it will drop to 20 at idle. I've used my mighty vac on the return lines they held 15hg vacuum and I have done a return test and both banks returned 35ml. I'm out of ideas for the old girl thinking about trading for something a little newer.
