I was careful to make sure the seal was centered by installing three bolts
very loose and installing the pulley to center the whole cover. Now I did
have gasket sealer on both sides of the timing cover gasket, and maybe it
could have inhibited the centering, but I was as careful as I could be.
Snugged the three bolt and then installed the rest. It wasn't real easy to do
with the engine in the car. I even put a small amount of silicone sealant
around the oil seal.
I am just at a loss to why it is still leaking. That is why I think it could
be a pressure thing. Just not sure.
