440.
My pass. side valve cover has a leak in the lower rear corner.
This leak 1st showed itself when I re-did my cover gaskets to fix another leak.
Took two tries to get it to seal that time. That was using a set of cheap moroso covers.
Now I'm trying to seal a set of factory 70 440hp covers and am getting a leak in the exact same place that I had before.
ie: two different sets of covers - leak in the exact same place.
Must be an imperfection in the head's surface.
Short of getting that smoothed out, do you guys have any tips on getting a troublesome gasket to seal?
I've tried both rubber and rubber-coated fiber types (both fel-pro) with form-a-gasket as sealant.
I'm on my 3rd try, now. Ugh.
