Alright, here goes! I'm not a car person, my husband is, but I hope I can describe everything sufficiently. 2002 Dodge Ram 1500
, 4.7, 4WD, automatic. LONG STORY SHORT, thermostat closed, lower radiator hose blew off, head gaskets blew, heads warped. $1200 for a rebuild and my husband's step-uncle planed the heads. Rebuild included: head bolts, main bearings (he ordered standard, yes, it was a huge f***ing mistake, I'll get to that), timing set, thrust washer, rod bearings oil pump
, lower gasket set, cylinder/head gaskets, piston rings, oil pump screen, MAP sensor, and fuel injector
o-rings. I'm just repeating what the order confirmation says, because it's easier than trying to remember everything. Anyways, got all the new parts on and did the break-in drive at like midnight. He drives it to work (20 miles away) the next day and then calls me on his lunch. Says that when he comes to a stop, the oil pressure gauge drops to zero. He figured it was the sensor, so he bought one and replaced it right then and there in the O'Reilly's parking lot. Now mind, the thing sounded/sounds a damn sight better since we bought it, now that it's been rebuilt. Well, that didn't work. Fast forward, he got a job at a Chrysler/Dodge/Jeep/Ram/Ford dealership. We had discovered the "select fit" main bearings before that happened. Asked THE Dodge guy in the shop, and he deciphered all the numbers on the main bearings that came off, they were original. BBBCB is stamped on the crankshaft wheel. So this guy says to follow that, and we do. Yes, my husband put them in the right places, before you ask. I was there. Also got Plastigage to check tolerances. THEY WERE ALL WITHIN THE RANGE. Got it all put back together (again) tonight. Started up just fine, still sounded damn good. He let it run until it reached operating temp, and the gauge didn't move! Of course, we were excited. Took it for a "test" drive. Drove to the next town over, about 10 minutes. Get to the first stop sign and whaddya know? Pressure gauge drops to zero and dings. I might have cried, I might have swore like a sailor, I might have screamed, I might have a very sore or sprained wrist right now from pounding on dash, ya know.....anyways. My husband is so done with this POS. So am I. And yes, he did the gauge test with the turning the key on and off however many times, all of them work just fine. He'll be asking the guy at work on Monday for advice, but I figured I'd throw our tale of adventure up on here and see what happens. Any and all advice is absolutely welcome and appreciated. Thanks!
