Could the intake manifold gasket in a 4.2L V6 be the cause of all cylinders getting coolant in them you did a compression check and all was good Cant figure out how coolant is getting into all the c?

Sounds like the head gasket may be leaking to allow the coolant to get in the oil but it it still sealing well around the cylinders.Yes, lower intake manifold gasket is probably leaking. Very common in 1997 and 1998 models. Good engine, just needs sealed up.
