You would eventually find water in the oil, or it would look milky compared to normal oil.
How do I change the head gaskets on my 1998 ford explorer?
Head gaskets, head gaskets, head gaskets
Yes you do halft to pull the head, because the gaskets are under the head.
Its possible a quick fits
intake gaskets are between the head and intake. head gaskets are between the head and the block..
You will need the intake and exhaust manifold gaskets. I would also install new head bolts.
yes
Head gaskets are supposed to last the life of the engine. There is no "care" specific to head gaskets.
I was not aware that headgaskets were repairable. I have always replaced them with new gaskets. If you mean who replaces headgaskets, then that would be an engine mechanic.
There are ( 2 head gaskets ) one head gasket for each head on your V6 engine
YES
Subaru 2.5 liter engine has a problem with head gaskets. If you have not had your head gaskets replaced, that is the first thing I would suspect.
