I have a NH l-425 loader with a wisconsin vh4d motor that blew up. It actaully made some pinging noises, puffed with smoke, then leaked all of the engine oil onto the ground. I am located on Mass and I am wondering if anyone knows of anyboby who either repairs these engines or sells them rebuilt. I have searched online, including ebay, call New Holland, and everywhere else. The problem is that the parts are hard to find, and the Wisconsin company has had some financial difficulties. Thanks AL
