Water in the intake-bound up-IMPOSSIBEL DREAM?

I found another moter (6.9IDI) for a spare-parts in a bus,,,the moter will crank over a littel,,not a full revolution,,,I tried to roll the engine over with a breaker bar-turns kinda easy till you get to 1 spot,,,figured there must be water in a cylinder? (cant compress a liquid) took the air filter off and looked in the intake-sure enough,,there is water in there-------I was wondering what happens if I take the glow plugs out and spin the moter over? Is there a CHANCE that I can spin it over-blow the water out of it-put the glowplugs back in it and start it-drive it home----or is this an impssibel dream? AND-what ealse might I do to accomplish my objective of driving this home??? Thanks,,Parker

That's what I would try. Do you think the water is coolant, or do you think that it was simply water that leaked in from rain or something. I remove the oil drain plug and let the water in the oil pan drain out too. I've had this happen on a tractor before. Rain water went in the stack, and down into the cylinders. Water was on top of the pistons and a lot more in the pan. I drained the water out of the pan till only oil was coming out, and replaced the plug. Removed the glow plugs, cranked. Replaced glow plugs, and cranked it with the fuel OFF. The compression was really high, since there was still some water in the cylinders. Once it was turning over really well with the fuel off, I turned the fuel on and started the engine at low (300 or so) RPM.

You don't have the ability to start the engine at 300 rpm, you are limited to idle speed, which will have to do. I would remove the fuel-shutoff wire from the injection pump and crank it without fuel before you start it.

Any water that is left will evaporate as the engine warms up.

Really? I've pulled a bunch of them, and I haven't had a problem. Then again, I assume that the 6.9 has he same type and placement as a 7.3. I have changed plugs in a bunch of IDI 7.3's.

Oh, *that* old problem. It's the same on the 7.3's. I have never had one like that. I found one plug that had the end partly gone. It had been like that for a long time, so I didn't worry about it. I just put a new one in and forgot it. As far as the head removal goes, I would be more inclined to put the metal part back in the hold and forget it. If it is lodged, then it's not going any where. And you can run on 7 glow plugs.

The nice thing is that if you are hydrolocked like the original poster, the water might drive out the broken glow plug.
