I did end up going in the garage and cleaning out the wax that was on the truck side, as soon as I poked it green coolant started flowing out. Is it possible to put the hose in one side of block to flush out the other side? I don't see why not. Also the backing plate that covers the IP gear...

It was Valentines day, so no work on the M1123 today. I will start with pulling serpentine pully, then next harmonic balancer. If the plate had a little more room I could fix the IP sprocket that has the broken key. I am going to clean all wax I can get out and I have hot spigots in the...

It's a soft wax like a toliet bowl gasket. I'm going to clean it out before I put everything together.

Has 71 miles on it. Thank you! It has to be wax from when it was built. Full of bright green antifreeze.

Water pump is off and just like I thought. Front key is sheared on ip drive. Lucky timing chain cog didn't shear otherwise valve damage. Found a weird wax in water pump housing. Could this be wax from when engine was built?

The Injection pump has a separate gear drive in front of timing chain cog. It will shear the front of the key off if pump freezes. As soon as I get front of engine torn down, I'll post pics. This radiator is kicking my butt. Now I have to remove shroud with 8-11mm bolts under radiator. This...

Whole radiator has to come out. At least with 71 miles every bolt spins right off.

Can't remove fan without pulling radiator? There is zero room in here. Got fan blade bolts off and need 1/2 inch more to remove.

Looks like I'm pulling the harmonic damper today. Should it be replaced or if the rubber is fine, reuse?

Its not rotating because the key broke on the cam gear below. Its made to do that if the injection pump freezes up. I had to do some 6.5 Chevy truck searches to see that this happens when the IP is bad and froze like mine. The crank has a chain that runs the cam, and on the front of the cam...

I have to pull fan and water pump and then once I get front cover off I'll see what happened. If the cam pin sheared I'll have to reset timing with marks on gears like you say. But first I have to pull plate off. Do I have to pull fan off to remove water pump or can I leave attached?

Could it be the shear pin on the cam gear?

Nothing moving in injection pump when I turn crank. Could the pump have frozen and chewed the gears off?

Started a new thread.

I feel like an idiot. Works perfect. Thank you.

I have the 200amp alternator, the pully spins without engaging the alternator. Just spins.

Should I disconnect glow plug box? I don't want to burn glo plugs.

I've looked everywhere and can't see how to turn the crank as the serpentine belt has a adapter that bolts on front of crank. Is it safe to bump the starter to move up bolt access? Or is there a special tool that you can move crank with?

Did your old gasket come right off? Part of mine stuck to heads.

Oh that pic was before I stuffed paper towels in each port. Trust me I vacuumed and used my compressor to blow any dirt by intake ports before removing. It's weird that the upper and lower lines on ip were froze so bad. The others I could almost do by finger after initially loosening.
