There’s a recall out for the coils on some 1.8T’s. Part of it goes into your model year, but I can’t say whether or not yours is covered. Have you checked into that? I’m curious, though…why was the valve cover gasket replaced? Was it leaking oil into the spark plug cavities?
FYI, this fault brought mine to a standstill, and had to be towed for repair. It ran…barely, and not much above idle.
