Re: Valve covers

Yes it can. Sometimes rain or high humidity can do this. Run the engine and hope. If the crankcase oil turns milky let us know. We probably will point and laugh but we'll help ya.

Re: Valve covers

It usually helps if we know what were working on.
The 4cyl and v-6/8 has a different setup.
Sometimes the breather tube from the valve cover has a PVC valve and it clogs and won't clear the vapors or fumes from the valve covers.
Clean it or replace.
All motors even new have a bit of blow-by.
This might be your problem??
