One of my friends father has a 1994 Escort Lx that dropped the common valve seat on cylinder #4. I tore it down the other morning and found the head and piston all beat to hell. I expected this, so I got a rebuilt head on Ebay and a engine gasket kit from Felpro. What im needing to know is where is the best place to get a new piston and a set of rings. They are unavailable from Ford. I was a dealer tech from 1992-2004, so I know what Im doing, just need to know where to get the parts from. I may try a machine shop, but im wondering of they will sell me just one? Never bought just one. Always a set of pistons and a set of rings. You guys know of an internet site that I could get this from? Much rather do that, than have to deal with a machine shop, let alone, the mark-up. On the flip side, the car only has like 77,000 miles on it and you can still see the cross hatch marks in the cylinders. If I can find a piston and rings, I can have this thing back together in a few hours. Thanks for any input in advance....
