At 200,110 kms, this engine blew a head gasket, and I replaced it with a used engine, then rebuilt this one. Before I could put it in, I sold the van. Redone top to bottom. JB Precision did the machine work. New bearings, rings, valve guides. Cleaned the crank and the bores. The rebuild (parts and machine work) cost me $900. This is a bargain. I'll guarantee it for three months.
