Conrod Conundrum

Philth has been chasing a knocking noise on his 400 engined Chally. He has now nailed it down as #6 big end. The bearing is knackered but hasn't spun. The conrod side is fine but the cap has ovalled. Is it possible to just change the cap or is it new conrod time? He puts the damage down to a mate at a wedding he used the car for revving it too hard while Philth was "observing" the fine exhaust note from the rear
Luckily it looks like the crank has no damage 8)

Do they have to be line bored? IE is the cap machined to fit the rod?

Is that a crack on the right hand side of that cap?

Any reason that one was getting starved of oil maybe? I am sure it had all new bearings when put together.

Hi Dude, overrevving streches the bigend out of round. Do not re-use a strectched rod!!!! It can be re-sized but very unwise as it might fail altogether. I have a set of 400 rods if you need some. Best wishes Baccarudajon.
