good news!

good pressure test tells you that the lack of compression is not due to a cracked head or cylinder block. It also tells you that the exhaust manifold is ok.

I think I would be looking, as has already been suggested, at sticky valves.

Pull the plugs and turn it over to see if the valves are moving. More conclusively, pull the valve cover plate and see what you can see there.

Hope that helps,

Peter
