For the past few months I have been having some oil usage problems.
It will go from just under the top dot on the dip stick to between the top and bottom dot. About 6 months ago I bent my stock valves and then bought new skunk2 flat faced valves. The guy that does my head work didn't change out the valve seals because they were still fairly new from my engine buildup. Also these were not factory seals but I had gotten them before I knew about the factory parts being the best.
Now heres where my question comes in. Would keeping the same valve seals cause enough crankcase pressure to make my oil pan start weeping cause before I had no such problem with leaks or anything.
I would really appreciate any input that anyone has about the subject.
