I have a leak across from 1.Looks like it it coming from in back of the timing cover
but I cant pinpoint it.Any ideas?Thanks....Bob
Yes, sounds like the timing chain cover gaskets
are leaking. The cover has 2 coolant passages.
The gasket on one or both are leaking. After
removal, inspect the cover for corroded aluminum.
May need to have the it replaced as well.
