Case 1190 water in cylinders

[Tituspawpaw]

I have a Case 1190 that my dad and I purchased about 10 yrs ago. This has been an excellent tractor. The amount of power it has is incredible. Recently my son was bush-hogging and broke the tailpipe off of the muffler. We had been putting a bucket over the muffler after use to keep the rain out. With the drought we have been experiencing, my son forgot to put the bucket over the muffler and we got a big rain filling the cyinders with water. I pulled the injectors and blew the water out of the engine, put everything back together and it ran like new. A day or two later a gust of wind blew the bucket off and here we go again . I repeated the above process but the results were not as good as before. I can crank the tractor but when I give it more throttle it starts to misfire and smoke bad. I am planning to drain the fuel tank and change the fuel filters, which I know can only help, but I am wondering if there is something else I may be missing? Any help would be greatly appreciated.

Get the muffler fixed is the first order of business after you get it running again. You have a solid stream of fuel to all of the injectors? I am just tossing a reply in here so that some of the wiser folk can give you more to work with. Good luck on getting it back to full power again.

You haven't mentioned the oil, but I assume you checked for water down there as well, and probably changed it. If the engine runs smoothly at idle or low rpm, I doubt the injectors or fuel system in general are part of the problem. Is it possible the engine was cranked over before the injectors were removed? The engine won't turn very far with a snootfull of water in one or more cylinders, but a good set of batteries and a stout starter can pack quite a wallop. That Case is pretty tough, but I've heard of lighter engines bending a rod under these conditions. Even if there is no internal damage, the water soaked rings may take a while to clear off and for everything to get lubricated/functioning again. If the bottom end sounds OK, I'd suggest letting it run at 1200 or 1400 rpm for a while and see what happens. It may well clear up.

What he said

Also, what colour was your smoke?
This may provide other clues.

Hello,

And thanks for the replies. I did try to crank the engine before I realized what had happened. It only rolled over maybe once or twice before locking up. I did check for water in the oil and there wasn't any. After I posted my question yesterday I went out and worked on it some more and think i may have found the problem now.... The line on top of the injectors that returns the unused fuel to the tank is twisted/kinked on top of one of the injectors. I think this may have happened after the second rain down the exhaust incident. I checked on that part at the local Case dealership and it was $85 (OUCH!!). The clerk recommended maybe going back with a rubber line instead of steel tubing. He said most of the newer tractors are that way. Sure wish I'd have fixed the broken muffler sooner.:ashamed: The guy also said that the tubing line being kinked would definitely affect the way the engine ran. I had a pretty strong suspicion that it would.
