I own a 95 Escort LX Automatic with only 61,000 Miles. recently I was driving and lost power and started to hear a tapping noise in the engine. The engine then died. Turns out the engine had seriously overheated- the temp sensor for the dashboard gauge was defective, so I may have been overheating for awhile. (gas milage had seemed poor lately) The waterpump is completely shot. The engine now runs with no unusual noise but has limited power. A dry compression check of the cylinders reads: 165 / 106 / 80 / 115. When I do a wet test with oil the results are 191/ 136 /103 / 160. the differences are 26 / 30 / 22 / 45. My question is do I only need to replace the head gasket. Or should I be thinking about replacing the piston rings also? The car is stuck up in the mountains and I do not think it is possibe for me to pull the engine, but I know the head gasket repair is possible. and the book says it is possible to pull the pistons without pulling the engine. any thoughts or tips would be welcome.
