Just to let you know..
If the cap is warped..
( your not going to like this )
Chances are you’ll need a replacement, or it may be abled to be honed.
In either case it means you’ll need to send the bare block, all the caps and hardware to a shop to have them honed to match.
Now depending on how far they need to hone the block and caps, you may need a new set of bearings to compensate for the machining.
Depending on the condition of the journals on the crank, you might want to consider getting it reground.
In which case will aslo affect the size of the replacement bearings.
