how much can be done without removing engine ?

How feasible is it to do shells and rings without removing engine on a G60 ?

It's not too bad to be honest... obviously you can only do the big end shells, as the other bearings need much more stripping off to get at 'em requiring the engine to come out.

 

I've done shells and rings on both a KR Valver and a PG G60 without removing the engine in the past with no issues... 8)
