Hi, I'm new here, just bought a friend's 96 740il with barely 98k, beautiful shape. They drove the car a year ago and overheated it, and I'm guessing that they did so all the way home. They did a owner installed new water pump at home. The car starts, runs smoothly with a slight skip after a year of sitting. After running for 4-5 minutes, the temp gauge is normal, but the car is boiling over agressively. I towed the car home, did a compression test (actually twice to compare results) and I've got the following results: the corner cylinders are higest ranging from 175-200lbs, the center two cylinders on each head are 122-155. Is is possible that a car with failed head gaskets or other damage could still have compression as high as 122-155? Any chance this might be something other than fatal? Any help is appreciated!!
