Hey all,
I have my 98 motor (150k) on the stand right now and pulled off the intake manifold. I noticed a lot of oil sludge in all the intake ports of the head (enough to scrape off with a spoon) so I decided to separate the intake in half to try and track down the culprit. To my surprise I see oil sitting on the bottom of the lower half manifold. Enough to swish around. The entire gasket is soaked in oil also. Is this normal?? 98's don't have an egr so could it be a faulty pvc? Is there anything I can eliminate off the motor to prevent this? Maybe install a catch can? Could blowby actually cause this? I want everything running perfect before I throw this baby back in. Hoping to avoid rebuilding if I don't have to. Any thoughts?
