I recently put too much oil in my JD 790 and it blew out white smoke and quit. Oil was ontop of the pistons on on the fuel injectors. I cleaned the oil and tried to start it. It would not turn over. The starter would click. found out that #3 piston bearing bolts when loosened will cause the crank shaft to turn freely. Question: do you think I need to pull the piston and replace the bearings?
