My understanding is that oil leaks usually occur at the bottom corners of the timing chain cover when you replace it. The kit I got from Fel Pro has a piece of gasket specifically for the bottom of the timing cover (or top of oil pan). So I plan to clean those two corners up really good and then use an abundance of RV sealant. It would be extremely disappointing to get the whole thing back together and then have an oil leak at the bottom corners. Any other suggestions to prevent oil leaks at the bottom and corners of the timing chain cover? Thanks Paul
