This is a common problem in these engines I have have it a couple times it’s the condrod bearing has failed unfortunately it’s a one piece crankshaft so you would have to replace the whole crankshaft £220 or you could pick up a used bottom end for less than half the price lol however often if the noise gets quite loud the the extra play in the bearing could allow the piston to come down too far am may shatter crack at break the fin off the piston
