Is this possible? About 3 years ago I bought a Dodge pickup truck with a blown engine for $500. The prior owner had driven it after the serpentine belt broke and it "seized" from overheating. When I first got it I changed the serpentine belt, put in a very low-viscosity oil, and tried to start it to see if could hear what was wrong. It ran but burned oil, a bad miss and I diagnosed it with a bent valve. Well, I parked it in hopes of one day rebuilding the whole engine. About once a month I would start it and let it run for a few minutes just to keep things loose and charge the battery. Last week I started it and forgot. 6 hours later I remembered and ran to turn it off. But it was running perfectly? No missing, no oil burning, and the valve noise was gone. It appears that letting is idle that long fixed the valve. It was not bent, just stuck. I have driven it around a couple of times now. Not really trusting it but I had it on the freeway at 80. The tires need replacing now but I think the truck fixed itself. As I asked it this possible?

Don’t forget boredom. I’m guilty of it. Boredom eating sucks at times.
