I have a 2000 Cadillac Escalade truck.It is leaking coolant in the engine oil.The car runs okay.It does not overheat.I want to know if it is an intake manifold gasket leak or a blown head gasket or something else?
I am sure you do want to know. Run a compression test, low compression combined with a failed coolong system pressure test points to a head gasket. Good compression with a failed pressure test points to intake gaskets. It could also be a cracked head or block. Taking it apart is the best way to confirm.
