Had the gasket start leaking where the oil filter housing mounts to the block on my late L3 with the 670 motor. I replaced with a new gasket, cleaned everything up and used black permetex/gasket sealant. Put it back together and it leaked in a different spot of the gasket. Ruined it taking it apart so I bought another new gasket and installed it dry. It still leaks. What am I missing? Should I use sealant or not? If so, what type? Thanks in advance.
