Dave, all I have is sympathy for you, but I am deleting this quickly just in case my '81, which seems to almost be as it should be, gets any more ideas. I've had all the strange and scary noises I ever want. Yours sounds like it could be a lot worse than bad motor mounts, unfortunately. BillR

Almost at home, this afternoon, after completing a 45 mile each way high way trip I heard a terrible noise. Sounded as though it was coming from behind the dash while in the vehicle and resmbled the sound of a broken water pressure line but more intense. However, with only a minimal loss of power, at first, the a return to normal power all gauges showed good. no change in water temp., oil prressure cruise or climate control activity. Pulling in my dirveway, maybe 1 or 1 and 1/2 miles since the onset, I immediately shu the vehicle down. The engine stopped but the noise did not! Upon leaving the vehicle I could really hear the noise and it was extermely LOUD. I opened the hood and decided the noise was comig from the area of the air filter/turbo area. Both were shaking and I could feel a slight vibration. Occassionally a whif of smoke would come from the area near the transmission dip stick and I would see aspark from the area where the transmission and the engine unite. I panicked and began pulling any relay and fuse I could lay my hands on, in the area near the brake reservoir. Still the noise, shaking and smoke continued. Finally on the passenger side/front of the engine compartment - mounted on the wheel well - I pulled a small four connector relay apart form the wiring and the noise, vibration, smoking and sparking stopped. When the relay was re-connected none of the symptoms were again seen. When trying to start the vehicle in any gear except park or neutral no atempt to start the egine is witnessed, just as it should be. However, when in either park or neutral I hear the familiar tonation of a burned out starter turning while no attempt to star the engine is found. Other than a dead battery, after sitting for several months, about two months ago this vehcile has never given me any challenges starting/shutting down. Any clues folks and how could I test to see if any or your theories are correct?
