Went to start the dozer today and it sat for 3-4 weeks. Some one was messing with it, throttle lever was at full throttle, bucket was off the stack and batteries are just about dead. One of our guys try starting it not aware of any water problems.It turned over quite a few revs, smoked and ran out of juice. We know theres water in a cylinder, its been spun over a several times but most of the time it was very slow because of dieing battery. I drained about 10 oz out of the exhaust manifold by lossening it. What are the chances that a push rod went? Im gonna pull the injectors and suck the rest of the water out so we dont loose it to rust. Any other easy things to help me with? I cant tear the motor down where its sitting unfortunately, i need to get it running quick and easyily as possible. So if anyone might have so good news it would help alot? Ive been told all kinds of bad stuff allready.

 

how would a pushrod have an effect on water passages? I would think if you had water in a cylinder it would have to be a cracked/broken head or block or your head gasket went in a BIG way....

 

If you'd "hydraulic-ed" it, you'd probably know. It's when a cylinder gets stuffed with water, then continues rotation in spite of a hole full of water that's got nowhere to go. It usually gives you a bent connecting rod.

In your case, pull the glow plugs (if you got 'em) or injectors, then crank the engine with a charged battery to blow out all the water. When you're sure the holes are dry, put it back together, bleed the injection system and fire it up. Should be alright.

 

I didnt clarify it right sorry. The water is from rain entering the exhaust stack. The engine was in good working condition. Im wanting to know the possibility of bending a push rod when it turned over and compressed the water? When it supn it went fast for a few and slowed down then speeds up for a sec and slows down like when it would hit the compression on the flooded cylinder. It didnt stop completely but you knew something was not right.

 

Stinkindiesel is right.

The problems are usually related to connecting rods. The idea of pulling an injector or a glowplug is to give the water a place to go. Then by cranking, you will force the water out. You can usually hear a problem when you are purging the cylinder of water if there is one but not always. This is a relatively common problem in marine engines.

Depending on how important the piece of equipment is to you should determine how much diagnostic work you want to do before you crank it over again and how much it is worth doing after you get it started. If it starts and runs well and you don't like it that much, just run it up to temp for a while and you will most likely be fine. However, if you really like it, then pull your valve covers at the least and take a look if not find a way to look into the cylinders.

Good luck.

 

If you had water in the cylinder you would only get part of a crank. (cant compress a liquid) Unless you have one heck of a starter and it immedeatly bent a connecting rod because the water had no where to go. The good news is that even if you bent the connecting rod a little bit you should still be abel to run your machine.
If your engine spins over I don't see why you would be worried about additional water in the cylinder it would be gone
You wont bend a pushrod from water in the cylinder.
If it was my dozer I would give it a shot of either and see if it will start. As long as you don't have glowplugs or intake heater)

 

Well im glad i got some positive feed back cause yesterday i got none. Im gonna pull the injectors and see what happens and get a new battery in it. I think one is fried, when i hooked the jumper cables up the voltage went down instead of up.

 

No way you bent anything with just the starter motor.
I had the same experience when kids messing around took the can off the stack on my D-7 parked over winter.
Even with a fully charged 24 volt system it wasn't enough to turn the engine over. Had to pull the injectors crank to expel the water. For extra measure shot some motor oil in each cylinder before replacing the injectors. Fired right up and has been running fine for years.

 

If anything I would say your going to have some rust issues from water sitting on rings and valve seats and stems. I agree with all on the hydro loc. I watched a bronco cross a river and hydro.....You could'nt miss it gawd awful noise and an immediate stop of the engine. Your starter with a weak battery couldn't bend anything in a small gasser much less a diesel hardened system.

 

Well i took the injectors out this mourning spun her over easy and threw out about 2 cups of water. Sprayed some areokriol in each one while it sat till i put it all back together. started up just fine in about 4 revolutions. Sounded just like it always did. My only other question now. When i poped out the injectors there was no oring on them but there is a grove, and theres no indication of any orings being in there at all. @ of the bores were so clean it was like a mirror so i no there wasnt any ring in there. Is there suposed to be? I didnt notice it leaking at all but i didnt get to spend much more time there, after i ran it for 15 minutes and had to leave. Saturday im gonna runn it good and change the oil and put the covers back on.

 

Like many injectors they seal with a tapered fit.
You'll be fine.

 

So I got water in my tank and tried to crank after I drained the water out of the filter. Nothing. The guys at work say i should drop the tank and drain out all the fuel. Should I do this then put good fuel in, and then loosen the injector lines and pump fuel through them or do I also need to pull the injectors to purge the cylinders like on the dozer. Thoughts?

 

No need to pull the injectors, just drop and drain the tank.
You may have to purge air out of the bleed screw on top of the filter.

 

I had an experience with an old Gallion road grader , it had a 4 cylinder detroit in it, water got in the exhaust on a warm day in the winter , filled up a cylinder , and then it froze... i was able to roll the engine until that piston was at the bottom, and use a propane torch through the side hole, and through the intake port , to melt the water , and blow it out with an air hose

 

That doesnt sound like much fun. I had it running for a while today and it was great till i noticed oil everywhere. I ripped the dang valve cover gasket when i put it back together.
