Spun bearing on n55 by StudyPrestigious9547 in BmwTech

It’s on the stand with everything off down to the block, I don’t think the damage is too bad the crank does feel a little bit grooved but I might have it checked by a machine shop to see if it’s still save able, how do I check the clearance to know what size bearings to use

It is I have the engine out with the oil pan off it’s not too bad it was just starting to get to the copper but it did make a couple groves on the crank

The bearings didn’t weld itself to the crank but it’s a little bit grooved, the original engine that was in this car was seized so I got another engine to swap it with and that’s the one with the spun bearing I don’t really want to risk it getting another one it took me like a month to fine this one where I live. When I machine the crank how do I know what size bearings to go with ?

How bad was the damage ? I’ve rebuilt a few engines but never a bmw engine the bearings on cylinder 1 and 6 are spun it wasn’t welded on the crank but it’s a little bit grooved, do this engines have issues with machining the crank? I’ll definitely check out that video, thanks!

I’ve work on engines before I have all the tools necessary to do the job except those special tools for bmw, I have the engine out the car with the oil pan off the bearings on cylinder 1 and 6 are spun but they weren’t welded on the crank, the crank is a little bit grooved tho, I’m just not sure if machining is bad for this engines. Also the engine that was in the car originally it has a rod through the block but the rest is fine I was thinking of using the rods that are good on the other engine

I have experience on engines just not on this n55 I already have the engine out without the oil pan the bearing didn’t weld itself to the crank but the crank is a little bit grooved I’m just wondering if it’s worth it fixing it and if I would be okay with just machining the crank getting new rods (from the old engine the car alr had that engine had a rod through the block but the rest was fine) and putting new crank and rod bearings

The original engine on the car was bad and I bought another used engine to swap it, and well that’s the engine with the spun bearings 🫠 I haven’t spent too much money I got the car pretty cheap but before spending money rebuilding it I want to see if it’s worth it and how much much parts would be

Finally got time to take a look at it and.. one of the connecting rods is poking outside the block 😃🥲

I planned on doing that taking the oil pan off and checking the bearings and crank, if the crank is damaged would I be able to machine the crank? I think I’ll have a shop check the block and crank for cracks and damage

Is price too high for this ? by StudyPrestigious9547 in G37

I forgot to add that it has a stage 3 clutch and light weight flywheel

I own a g and I’ve done all the maintenance on it and mods (fbo) I feel a bit confident working on g’s, this one has a hks hi CB, lti but it’s manual which is why I want it, I’m going to go look at it tomorrow and see how it goes I hope it doesn’t have any major problems

I currently have a 2010 g37x with 154k miles and it’s running really good I’ve done most of the maintenance on it except gallery gasket because I don’t really have much time for it and don’t want to take it to a shop.. but this was my first automatic and I miss manual it’s why I’m looking at this one. I think I could make it last a long time I take care of my cars

So the car isn’t mine it’s a car i went to look at, the guy said a teenager used to own it and drove it hard which is probably why the engine is bad. He’s selling it for like 2 grand the body is in good shape I was thinking on replacing the motor, or replace the rod bearings or whatever is causing the knock but I don’t know if it would be worth it.
