In this clip we are going to talk about how to determine if your valve cover basket is leaking. What we have done, and it is a good idea since oil will never go away unless you wash it off, we have taken and washed the engine just at the local car wash and driven it. Once you have driven it, we put about a 100 miles on it. You could see the evidence to where the valve cover is leaking. We have fresh oil coming out right here between the valve cover and the cylinder head.
