I started off having a struggling crank. It turned out that the pulley on my ac compressor froze. So I replaced it and sure enough got a strong crank.
In order to get to the ac compressor i took off the radiator, shrode, fan, etc.
Well I fired it up. It took awhile but it finally fired up. Then I saw a oil leak and heard a screacing noise. I replaced the HPOP.
I then hooked up the radiator and fired it up again. The oil leak stopped but the noise came back. I turned off the engine and now the crank is locked up. I tried to crank it again but it won't turn.
I don't know if it is hydro locked or internally locked up. I didn't have any engine coolant because I drained it to take off the radiator. Could that be my problem, how can I unlock it if it is hydro locked.
I have taken off the glow plugs and tried to turn it by hand but it is still locked.
The belt is off. I replaced the HOOP under the turbo. I as an oil leak on top of the manifold so I assumed it was the HOOP. When I try to turn it I can't. I already took off all the glow plugs and it is still locked. I'm wondering if I have to replace the engine.
The motor can't run without a functioning LPOP. At least not longer than it takes to deplete the oil in the HPOP reservoir. Once that's gone, there is no oil to fire the injectors. I don't know how long that'd be, but I'd guess it'd less than a few seconds.
However I agree. If he has all the belts off and can't turn the engine with the "big socket on the front of the crank pulley" method, his engine is screwed.
