L3 oil cooler housing gasket leak

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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.
