Engine problems
Hey guys, I just blew my engine on my 92 Ford Aerostar 3.0L. I was driving it hard on the highway, (I was running late as usual). When I got to where I was going I parked it and when I came out to head back home the engine was missing. So I limped it home and ran a compression test. #1=115 #2=110 #3=112 #4=115 #5=113 #6=0 wet test on 6 also came as 0. I don't have a air compressor or a cylinder leak down kit, does anyone know a way to check to see if I made a hole in the piston or if it is an upper engine problem? I'm on a tight budget and if I can pull it off I'd like to just rebuild that head, but I'd like to be sure it is the upper engine before I start pulling it a part to fix it. Any help or advice would be greatly appreciated.

Pull the spark plug. Try to get no:6 piston as close to the top then take a stiff wire with a small arc in it and move it around the top of the piston. If you blew a hole in it you should find it.
I bought a Ply Reliant that when I pull the head there was hole Burned through the middle of the piston. Looked like a blow-torch cut it. It was Anti-freeze leaking from a bad head gasket that blew the hole through it. All the oil holes in the bearings and oil pump was filled with melted metal that had hardened.

Well it took me longer than I meant it to, but I finally got arround to checking the piston, and I can't find a hole. Some one correct me if I'm wrong on any of this but since there is no oil in the coolant or vice-versa and since it doesn't really seem to be building crankcase pressure I'm going to assume that neither the block or the heads are cracked and that the rings are good and that I have a toasted valve. Someone correct me if they disagree I'd like any input I can before I pull the heads. (So that I can make sure I have enough money saved for it.)
