Hi, I was driving my 1978 omc770 loader when I noticed some white smoke coming from the engine, (engine is behind driver). I checked it and thought is was a leaky headcover gasket. I drove a bit more and heard some squealing and drove another 50 yards to park it. I noticed the oil pressure was at zero.
I also noticed the harmonic balancer was loose and the bolt holding it to the crank was almost backed all the way out. I tightened it and started the engine and still no oil pressure and noise. Shut it down immediately. I'm trying to figure out where to start before I pull the engine. Thanks for your help!
1. Does this sound like a rod bearing?
Can I fix this without removing the engine?
2. Does the harmonic balancer have anything to do with this?
3. What could have caused the loss of oil pressure?
