Kloudie,
Maybe after a documented failure due to a defect I may change my opinion however until then and depending on what the report says I still don't see and manufacture liability here. We have no first hand info on maintenance, repairs or maybe a hydro-lock scenario (other then what the prior owner says) on a eight to nine year old part that could have caused this failure. I would think that Yanmar would know of a defective batch of crankshaft as most engine of that age are well past the 190 hour mark. If GM or Ford had a 10 % failure rate so would have Yanmar had the same percentage just not the same number of parts. I would think Yanmar would have noticed a pattern. I can say that this is the only case of a broken crank that I can recall having heard , a very uncommon occurrence for this engine.I do believe that Yanmar would have covered this repair under warranty had it happened in the covered period.
As you suggested with Honda,( I am surprised that they did not honor a defective head gasket at 25000 miles...what was the warranty they were giving back in 76 ?) I doubt any manufacture would cover this crankshaft today so far past the warranty and with no know failure history.
Sometimes diesels suffer more problems with lack of use then with too much use, could be the case here......or simply the peril of buying used ?
I will hold any other thoughts until reworb has a confirmed report of defect. As I stated before I don't want to appear unsympathetic to his engine problem.
