I don't know an incredible lot about these cars, I just did an engine swap yesterday from 1991 Loyale into my 1987 GL. My '87 had almost 300,000 miles, still ran, but, it was time for a fresh motor, so, I put a 120,000 mile motor from my friend's totalled loyale in it. (It was rear ended)
It started easily, ran great, accelerated easily, it was a fun little motor. But, I was driving and suddenly the motor just stopped, sputtered out. The engine was warmer than it should have been, so, I thought I might have lost head gaskets, but, no smoke, no coolant spew, and it didn't sound like I grenaded the motor. It just died and refused to start again. It turns over easily, no wierd noise or hesitation, it just won't start. I checked the oil when it died and it didn't look like milkshake (when coolant enters oil). So, I don't think it's headgaskets.
I thought maybe I lost a timing belt, but, if I remove my distributor cap the distributor still rotates when I turn the engine over, which indicates timing. I know these cars have two timing belts, so, could I have lost te passenger side belt? I kind of think it would run, but, just run like spoob with half the timing. I don't know though. Anybody have any answers?
