91 accord ex 2.2 help
when the rpm's go over 4,000 it starts smoking does anyone have idea's what it could be, it doesnt smoke at all when u crank it or when under 4,000 so im comfused could it be the valve that plugs into the top of valve cover?

Yes, it definitely could be the PCV valve. But there's other possibilities too.
A new PCV valve only costs a few bucks. Normally I like to diagnose before closing my eyes & replacing part$$$, but this one is pretty cheap. |
