hey, my friend just rebuilt his KA and it was running fine, but alot of smoke and oil comes out of the blow by valve.

we tested my other friends S14 and no smoke came out of his.

and also the car isnt running quite properly. it sometimes jerks, and on the low end its sort of unstable. but in the high end it seems ok.

weird…

can anyone help?!

That shouldn’t be… (I assume you mean from the crankcase vent)

Double-check compression numbers and the PCV valve.

Good luck.

well the thing im talking bout is the lil valve (or hole) in your valve cover. on the left side. theres a hose connecting it back to the intake. but some people take it off and then put a lil breather filter on it.

right now my buddies car is spewing oil out from it and it smokes alot from there. whats wrong?

compression check, seen them do that when the rings were gone.
