Yeah, I suppose a glow plug could do it. Don't see it bending anything though, but maybe. I've been using ether for years. Never had any problems from it.
Wow, he must of had a long armMy grandpa had a bad back would sit in the drive seat with the hood up and window down and crank the motor while pumping the gas pedal and spraying the either in the air filter. seen it a few times when it would fire it would rev to 4k almost instantly. Its how he put a hole in the block on the 5.9 cummins we had in our water truck.
what kind of damage?When installing rockers/pushrods, the service manual has you put the engine in the "11 o'clock position (line on harmonic balancer lined up with pointer on CPS bracket). Putting the motor in the 11 o'clock position is to avoid lifter jacking (the lifter pumps up with residual oil pressure when the rocker/pushrod is removed). If the pushrod and rocker are installed with a pumped up lifter, you can get engine damage when the engine is turned over. In the 11 o'clock position, an oil drain path is provided so the lifters don't pump up. It may not be a problem if the engine has not been operated for a while, but it only takes a second to put it there and not take a chance. Cheers!
I have encountered this. Look closely at your rocker arms. If the engine was ever started with ether, more than a few times, and ether locked or hard rev, you likely bent the rocker at the fulcrum. If they all look good, in measurement and comparison with others, you likely have a lifter that is going bad. You will need to drain the engine oil through a mesh screen with a large magnet in it, looking for debris from the roller bearing in the lifter. Also pass a stick magnet into the pan looking for any metallic debris. Please let me know the results. you will also want to go to harbor freight, Northern Tool, or NAPA and get yourself a diesel engine compression tester.and I was not able to bleed the lifers down. I checked that and checked to make sure I had the push rods seated correctly.
I am sorry, I was not talking about your grandpa. I had forgotten you said that a day or so before.Well I can promise you he isn't working on any more trucks, seeing how's be been deceased since 2014. But regardless, I took everything back apart and inspected everything. Even used an endoscope camera to look at the Pistons and lifters (all looked great). Below is a video of everything running. Put the valve covers back on and the truck started running like #### again. Couldn't even get to 60mph. Took the covers back off and it runs great. It's like the gaskets short when I torque the valve covers down.
That's a terrifying thought, have you grabbed the pins in the gasket with some little vice grips or something, and seen if they pull out?
