LOL! I would like to know! The truck was running fine when I took it in for the replacement seal. It never even got really low on oil because I didn't drive it and when I took it in (30 miles), I made sure the oil was full. The leak wasn't major. I was told that the engine might have locked up because of low oil pressure, and since the guage was messed up after the work, and the guy said he checked the pressure several times before releasing the truck back to me but it was ok, I think something wasn't right when they put it back together. Is trying to start the engine and turn the motor over by hand the only way to tell if the engine is locked up? I wonder if I should take it someplace else to be checked or just scrap the truck! It didn't even have 90,000 miles on it
