One way to find out if a crack is present is to first clean off the outside (medial blasting works really well and gives a pretty consistent surface texture) then add some dirty ATF to the insides (I suppose one could use any dark penetrant). If there's a crack of any significance the dirty stuff will bleed through. Andy
