take the pcv valve out of the valve cover and let it run and see if it stops. if it dont clear up in about 5 min. thats not what it is. you can pull the valve cover and see if the drain holes are stoped up also. it shoulnt be the rings they check to good.


it1s10, no change when i took the pcv valve out...

also, pulled the covers again, drain holes were clear...

guess i might have to pull the heads...

I ran a compression test and all cylinders read 130-135psi dry..wet they ran 150-155psi..

i dont see how it could be the rings, the valve guides must be totally worn out. a qt. of oil every 100 miles is a lot of oil.

if the intake was sucking oil from the bottom side then i dought if it would idle good.
