Did you check the oil pressure sender below the filter? Is there oil around where the tranny bell housing meets the engine? Just eliminating the obvious first.

WELL ITS NOT A SPOT THAT IS COMMON THAT IT WOULD SEEM I NEED TO REBUILD ANYTHING? RIGHT? CAUSE THAT WOULD MAKE ME FEEL BETTER. IT SOUNDS LIKE ITS JUST SOME

I'm just wondering if its really leaking up there or if it is being sprayed up there from a leak somewhere else.

UHH, HMMM, I DONT' KNOW. IF IT WAS A LEAK FROM THERE, IT COULD SPRAY OUT SOME, SINCE IT IS UNDER PRESSURE GOING TO AND FROM THE TURBO

1revin7 had a bad rear main seal that caused oil to spray up onto the motor. I never heard of that before, but that's what happened to him. I had a leak in that area when I cracked the rear housing, but that would be accompanied by 0 oil pressure. It's possible that the turbo oil feed line could be leaking. Those copper washers will go bad once in a while.

I used to do this with my old motorcycle:



degrease everything around the area in question, then park it over a sheet of cardboard, and check it the next day...that'll give you an idea of where it's coming from, if there's a leak in the lower portion of the engine, I'm guessing

I HOPE ITS JUST SOMETHING ON THE OIL LINES. THANKS FOR THE HELP.

HOW HARD IS IT TO REPLACE THE REAR MAIN SEAL

Daiv Makitsu 03-12-2003 01:37 PM

would a bad rear main seal be accompanied by bad oil pressure as well?

You have to remove the tranismission, clutch, and flywheel.
