Hi guys just quickly a mate has blown his engine, is it generally advised getting the bottom end machined when refreshing it in this situation, or for any refresh for that matter?

Thanks

 

If you are meaning getting the crank reground then the main opinion on here is NO!! As cleaning out the oil passages in the crank cannot be guaranteed and you remove the hardened surface that the bearings run on.

 

Could mean bore damage ?
Whats the general thoughts on sleeves ?

 

I mean the block but yes if there is any bore damage would a re bore be the thing to do?

 

Yes,bore to next oversize so you start with fresh bores with no taper or ovality.
