It looks like the cam-chain is bunched up against the tensioner blade which is probably damaged and canít be replaced without stripping the engine right down, also you say you found a piece of metal in the sump, donít you want to know where itís from?

Its a false economy not to strip the engine right down, also youíll be able to fit a cam-chain without a joining link if itís stripped down.


That was a thought of mine as well. There is no better reason to strip and magnaflux the cases than this one.

Theres no bargain way of getting around this, either do it right or do it twice.

This isnt a job for calipers, calipers are reference only tools. You need a micrometer/telescoping gauges or bore gauges, to check for out of round/dimensional tolerance after the cases have been magnafluxed.


Hmmm. A blueprinted Exup mill. That could be serious fun.


Blueprinting comes after he knows the cases didnt get damaged by a wandering chain. What really need to be addressed is why the chain broke.
