Hi

Does anyone know if a blown head gasket might cause a "leak down test" at TDC to push air into the block (air leaving the oil cap and dip stick or is this 100% certain a ring issue? I can't find an oil flow diagram anywhere to see if there is an oil passage near cylinder 2.

Does anyone have any faith that this may be a stuck ring on cylinder 2 where I have 30 pounds of pressure (compression tested twice)?

I'm contemplating on my two options: 1 - replace the engine with a used engine (2.0) or 2: pull the head and see what this looks like or 3: dump some Marvel's Mystery Oil in cylinder 2 and leave soak for a few days.

Thanks
Jeff
