New cap, check threads, align hone. Or sweat.
Yep that's what I said too.I guess I'm the stupid one. If that was my engine, I would pull it, disassemble it, send it to the machine shop get them to check the main bore alignment. It could be the main bore alignment was off from the start. SOMETHING caused the cap to fall off. Maybe it wasn't torqued right. But how will you ever know what was WRONG unless it is checked out? I would not touch using that main cap with a ten foot pole. How the heck are you gonna check to make sure that particular main bore is still round? I'm sorry yall. I disagree here. Putting THAT back together is just a mistake. I wouldn't do it even on the lowest of budget engines. It's just a bad decision. Flame away.
you think the crank torsioned that much?
and didn't wipe the thrust out?
Hey op, how much money do you have to spend and is this your only car?
Rob, if it was mine and a fresh motor, I would pull it too.
But if it's just some old stocker and not rare, go for it.
There are plenty of forgetful people out there who either mistorque or use a chinese torque wrench to do it and end up 20 short
Well.....here's my point. No tellin what happened to that cap. No tellin how it was slapped around when it fell off. What it was beat against and how it was hit. If the crank throw hit it just right, it might not be round anymore. Too many mights and maybes for me. I mean Justin, we just don't KNOW what happened there. Can he file it down and make it work? Maybe. Will it lock up and break the crank? Maybe. Will it spin a main bearing. Maybe. Will it run for another 100K. Maybe. Till you pull it, tear it down and measure it, the maybes remain. Just too many maybes for me to armchair some advice and then feel responsible when his crank breaks slam in two on my recommendation. I don't seperate "mine" from "somebody else's" because I do everybody's like it was mine. Somebody doesn't wanna fix it the way I recommend and they wanna cut corners, there's somebody else down the road that can do it. You can ask anybody that's been around middle Georgia a while in the business about me and they might say something like "asshole", "sumbitch" and "prick", but they will also come right back and tell you I KNOW how to build an engine. I have a good reputation around here and I've kept it by not doin stupid **** (just my opinion, nothin personal) like reusin that main cap. LOL Just sayin.
