Looking for thoughts on this one. I have an engine (in this instance, a B Mopar 383) that is running in a car. It leaks like a bastard out of the rear main. It smokes and has lots of blow-by to the point that I and my passengers stink of exhaust after riding in it. It doesn't really smoke too bad out of the tail pipes at idle or under normal driving conditons, but if you hammer the gas, it will fog for mosquitos. As expected, it will consume some oil. It does not foul plugs, still has excellent oil pressure, does not run hot or overheat, starts easy and has tugboat grunt and ample power. Honestly, the engine runs fine. The car it's in is a driver at this point (at best). I don't really want to go through the time and expense of a complete overhaul that includes complete new machine work, pistons, etc. The symptoms I'm getting are telling me the rings are bad. I can get a full re-ring setup with new bearings, rear main seal, rings, and all new gaskets for like $250 and probably knock the job out in a day. I'm not looking to go racing. But if that could solve my smoking, leaking and oil consumption issues, it's a home run. Have any of you guys just done a quickie, hi-how-ya-doin engine re-ring on the existing bores, a few passes with a hone and just sent it? If so, how'd that work out? What would be the most wear on the bores where you'd consider it and where you'd consider needing to bore?
