Well the fuel thing could be a problem. I own a turbo car that requires premium fuel. I never drive it because this little town we live in has 89 as the best gas. So I know for a fact she is not/has not ran premium fuel, and she probably never new she needed to. But I also know she never beat on it and drove it hard.
I just don't think a blown motor would cause a squeal before it blew, you know? She heard a squeal, and lost power.
I will probably get the car at my place in the next few days. I'm putting on a new belt and changing the oil. Before I actually start it though, I'm going to do a compression test to rule out most engine problems. What is normal compression for these motors?
