I have two more questions as I continue to work (piecemeal) on the engine. First, there has never been a leak from the front timing chain cover or water pump. I actually have the gaskets, but have been reluctant to fix things that "aren't broken". B) When I got the engine out of the car, I could see that the adapter, that allows you to run a remote/external
oil cooler, was sealed to the block without a gasket....just billet metal to cast iron. They do make a gasket (FelPro #70135) for this interface and I wonder if I should use it or not. thanx again. steve
