Have a 97 2. 5L DHOC subaru GT, number 4 exhaust valve is just stuck open & no compression. The other cylinders all have 210 psi compression. Before I pull the engine would anyone know if these things have carbon or valve guide problems?

Pull the valve cover off and see if the valve spring is broke.

I don't do Subarus but I know some years have lots of head and headgasket issues,amongst other things. I think 97 is one of those years.

Hi
How do you know the valve is stuck? You can't see the valve spring by taking the cover off. It's more likely to have a burnt valve it does happen occasionally.
