I just ordered a case of three gallons.  That should last me for years.

Hi everyone,

My 8V71 has a problem.  The bus has been sitting for about a month.  I drove it 400 miles round trip while towing my car trailer, it ran perfectly the entire trip.  When I parked the bus it was running fine.... oil pressure good, antifreeze normal level, no noises, nothing notable.

Today I went to move the bus.  The engine cranked over a bit slower than normal but I expected that since it's been sitting for a month.  After about 10 seconds of cranking, the engine stops hard.  The starter just clunks after that.  From the rear controls I hit the starter switch a few times and by watching the clutch I determined the engine was coming up hard against something and stopping.

I used a pry bar to turn the engine back a few degrees and try to start it again.  The engine stops in the same spot. I turned the engine back about 20 degrees and try the starter again.  This time the engine cranks for a few seconds and starts, but it's making a horrible crunching noise, irregular, enough to cause the engine to shutter and shake.  I shut the engine off within 10 seconds.

I pulled the Vickers pump and the coupler.  Both were fine, the coupler was perfect and the pump turned smoothly.  I started the engine again, this time without the Vickers pump.  I had a friend depress the clutch as well in an effort to rule out transmission noise.  The engine started right up, oil pressure was 65 psi, but the engine made the same irregular crunching, chunking noises, shaking and bogging when it crunched.  I shut it down after about 15 seconds.

It seemed that the noises were louder at the back cover.  There was no smoke at all from the exhaust.

I'm looking for suggestions as to what is wrong.  It seems something is bind up in the accessory drive gears, but if it was metal wouldn't the engine just stop?  Or just break gears and stop running?  What should I remove next?  

This timing of this sucks, of course.  I'm in the middle of an expensive generator engine and alternator rebuild.

So what is the maximum height that a 4104 will be able to run-up on run-up blocks without burning out the clutch?
