This is designed to be a general engine question, not so much about my specific car. It is about engines in general, though I do have a Subaru EJ25 in case anyone was wondering. (EJ251 as per stamp in my car engine bay, it is not an EJ253 or a turbo.) So with that, let me ask so that I may learn.. of anyone were to brand this somehow a "dumb question."
Alright. So. That out of the way.. If the heads were to come off an engine, in my engine most likely because of eventually the Head Gaskets are supposed to fail, perhaps de-laminate perhaps just fail (they are doing fine at the moment as is the engine.) What other things can be addressed or fixed with the heads off?
Specifically.. Can piston seals and valve guides be addressed with the change of a head, or does the block have to be taken out of the car?
Quirky to Subarus, I have heard it said that removal of a Subaru engine is not a big deal. Also that everything requires taking the engine out, since it is low, wide, and flat.
My engine runs fine, this just so I can learn . ?
