Oil in rear intake runner
Oil in rear intake runner
The engine is newly rebuilt and has approx. 30 miles on it. I am experincing a ton of white/greyish smoke out the exhaust and also only about 7 psi of oil pressure on the stock oil guage.
The rear intake runner (closest to the tranny/underneath the secondary injector) on the LIM has a lot of oil looking buildup, while all of the other intake runners look clean. The ENTIRE runner is full of the oil substance. Enough such that there is even a black film covering the injector. I have fully spec'ed the fuel injectors and they are fine. I am next going to check the oil nozzle to see if it is faulty(Could this even cause this???).
Does anyone have any information on what could be the problem? I am hoping the side and corner seals are good, but maybe the rebuild was crap (Atkins Rotary)???
Thanks.

Sounds like an oil control ring issue. They may have pinched the rubber ring, forget the oil ring spring, the rubber all together?? Anything is possible. What may be happening is at idle oil is being sucked into the intake, thus, it is building up there. When you rev it the oil is being sucked into the combustion chamber.
Take the UIM off and try pushing a q-tip down to the intake port on the iron and see if it is oil soaked.
If it is running good at idle then I'd doubt it's a corner or side seal. Does it have good idle vaccum?

. I'm thinking another rebuild is in order.
