Shes alive an shes stayin alive!!

If you say so, i wouldnt trust what you can see from the top. You may as well go ahead and pull the engine since you have it tore apart anyway and atleast refresh it with rings and bearings. it will cost you less in parts than that fuel cell . have the pistons checked by a machine shop then put it back together. It will be money well spent and if you dont all that money you are spending on the top half may a well be pissed in the drain.
