I have a 1990 std hatch 4-speed D15, I am having a really strong oil odor once I drive it for a ways and warm it up. The oil level has not budged a single bit since the change, no oil spots, no signs of leaking (that I can see), no running funny, idles well, starts quickly, ect ect. I have been reading here that the PCV may be the culprit but am cannot isolate it to this. Anybody had this issue? Please help, thanks guys

 

Replace the PCV if you think thats it. It's really easy and cost mabye $3 at the parts store.

 

see if any oil is dripping onto the exhaust pipe

 

I didn't know the PCV valve was THAT cheap! No oil on the exhaust, none dripping anywhere, it's as tight as a drum. I'll just start with the PCV, I was expecting it to be a hundred dollar fix being older emissions crap.

 

Well, mine on an 89 civic at autozone was $2.99. Might have been a 94 del sol actually. But regardless, same sort of valve. Mega cheap. It's just a spring really.

 

brake booster also uses a 1 way valve which might work as well.

 

My guess it if you are physically smelling it then it is coming from oil on the exhaust. Either a leak somewhere or some old oil burning when it heats up.
