I know, I know, it's an M20, the valve cover gasket seeps.
I've had a steadily worsening leak at the front lower corner of the valve cover over the past year or so, no matter how new or which gasket brand I use.
It's bad enough that the front header heat shield is soaked in oil, and the #1 plug gets a little fouled from the seepage down the threads.
My question is this: is a head-coating, heat-shield-soaking size leak "normal" amounts of leakage? If not, what would be the fix?
I've actually begun to wonder if the oil spray tube over the cams might have a loose or backed out nut on that side, which might explain the localized heavy seepage.
Any advice?
