[QUOTE="charlesthomas, post: 233434, member: 7051"] If two experienced engine shops have looked at the cases and both came to the same conclusion, I'd be inclined to trust their assessment. Minor gouges in the crankcase don't necessarily affect lubrication, especially if they're outside the bearing seats and don't interfere with the crank's rotation or the sealing surfaces. The bigger concern would be hidden cracks or damage that could affect alignment. Since you've already got the engine apart, I'd clean the cases thoroughly, inspect them carefully under good lighting, and make sure no metal fragments are left behind. If the bearing bores are still within spec and the mating surfaces are flat, I'd probably reuse the cases rather than replace them. I'd put the money into a quality crank rebuild and new bearings and seals instead. That said, if the gouges are deep enough to make you question the integrity of the case, it's worth getting a third opinion before you button everything up. [/QUOTE]
