Dan;

In my opinion, the caps are poorly designed and prone to leaking. My Honda cap screws on and seals at the base via o-ring. Far superior and never leaks and it has as much blowby (320K KM) as the Volvo.

You can try to bend the tabs of the cap so it fits more snugly on valve cover but do this at your own risk. Cap is plastic and it's hard to get a good grip while bending.

Ensure the sealing surface is very clean too; IE where rubber seal contacts valve cover sealing surface. I believe that scratches in the paint can cause small channels where oil can leak through.

If I ever take the valve cover off, I'm going to file this surface flat. Of course I won't do that while the valve cover is still on car due to metal filings getting into cam area.
