Hey all. I was wondering what I should look for with my problem. My son borrowed fiero and it died on him. He said oil pressure went down and it died. When started cold it sounds ok but has slight knock when warm and less power than before. I have not heard it run. Going by what I was told that it sounded like may be valve knock. Oil seems fine but no pressure reading in dash. I wonder if it dropped a valve? any thoughts? thanks

Oil pressure dropped and then a knock? Sounds like it might have spun a bearing. Have you checked the oil for metal and such? Sounds like first thing you should do is drain it and examine the oil (can use a strainer or a magnetic pick-up tool) for metal content. If a valve dropped, you'd probably have much worse than a slight knock.

I'd drain the oil, check it, and then pull the pan and check the bearings, depending on what you find when checking the oil.

This sounds similar to what happened to me a week or two ago. Luckily it died as I was pulling into the driveway Not sure what it was but the next day it started and ran fine and it's been going great since. Well as good as possible for an old car in negative temps... Have you tried starting it since?

Put a mechanical gauge on there and check for oil pressure. If it is low, then you have a problem....

Is this type of engine failure caused by over revving?

Over revving can stretch rod bolts and spin bearings, yes.
