Hi

After some Daily driving Ive noticed oil on the valve cover. Only driver side, its not much but is it the gasket leaking around the breather cap or what ? Any ideas how to fix this ? For what I know it has allways done this. Red spot is where the oil collects. Maybe its the underneath of the cap ...



Regards Rob

Bad gasket on the cap, or hose connection leaks, or the seam connecting the top and bottom of the cap is leaking.

+1

and your PCV could be plugged or malfunctioning.

Okay Thanks

PCV works perfect and rattels like a snake when I touch it. So new caps it is :)

These old 1/4 turn oil fill caps are not like your new vehicle with a screw on cap with an o-ring seal. They will always leak. You could probably put a long tube like the racers use to and stop it some but without a great screw on cap and o-ring it is going to leak.

If the chrome cap is a breather cap it could be a little blow-by (oil vapor). Chuck

Another thought, some aftermarket valve covers do not have a battle at the openings, so the cap and gasket are always drenched in oil.

There is a plate so you cant see into the head, probably for protecting the oil from splashing out.
