You could use the same cap over as long as it isn't cracked or messed up where the bearing goes and where it mates to the block.
Have a local shop magnaflux it and make sure it's ok to use.
If you have another cap then just check it and make sure it's the same measurements as your old one was.
I do not have any extra caps. Or do you mean one of the other caps?
Check the threds on the bolts also.
The threads look fine on the two cap bolts
If the bolt threds are ok then the block is most likely ok.
Check the bearings on an other mains and pick a couple rods to check the bearings on.
Can you please explain that a little differently-not quite getting that
If all is well then re-torque the mains and all the rods.
If your willing to build a new engine,why not try first fixing what you have.
I would ask a couple of shops near you why they think this would happen and if they have seen it before.
I am very interested in fixing this engine-it was quite strong and about what I was looking for in a street engine
Was this a new or old engine???
