Oh woe is me. Here's what happened. I have a 1998 Ford Ranger Sport, 2-wheel drive with 98,600 miles on it. It was in need of an oil change but only late by ~2 months. Still, not good. I was leaving work Friday and suddenly my oil pressure dropped out completely. The steering wheel basically locked up and I barely managed to get to the side of the road. I called a family member who does side work as a mechanic and he said get off the parkway and to a gas station right away. This, as I've learned, was a mistake. I should have stayed where I was for a tow. But what's done is done. So I started the engine back up, and with the engine running and no oil pressure, I drove it ~1 mile to a gas station where I got a tow. The engine sounded like a machine gun the whole way. My father (also a mechanic) took a look and determined the synchronizer needed to be replaced as the grooves in the bottom piece of it had been chewed up somehow. He said he's never even seen that before. So he replaced it and the oil pressure returned, but the terrible noise of a machine gun remains to this day. My landlord (also a mechanic! geez you'd think I'd have a better grasp on this...) listened to the noise and said it was on the underside of the motor and apparently that's a good thing. He said if I baby the motor and drive like a grandma at no more than 55 mph in the right lane for the rest of the truck's life, I might be ok. tl;dr: I caused what seems to be minor damage to my engine by driving a short distance without oil. The engine now makes noise on the underside of the motor and I'm afraid I need a new engine. I was told if I replace the "crank" I'll be ok. Any alternative suggestions? Agree with that one? Think I should scrap the whole vehicle? P.S. I'm broke, so I'd rather not follow any expensive advice, but I understand if it's the only way to go, I'll figure it out.
