I want to thank a Resource Forums member ( and it's my bad ) I foregut his name, for the help he offered me. I purchased A used 5.9 from a recycle shop what I and the owner of the salvage yard thought was a good engine, when it was in the old truck it started and ran great and quiet, sounded too good, as I tore into it I discovered parts of the bearings in the oil pan, the original owner of the engine doctored it up by putting 90 weight into the oil. It was with the advise of the R F member and his help I was able get this resolved, the owner of the yard was duped and so was I and I got my money back. THANK YOU peterlo221
