6.9 diesel engine seized need help
I bought an 1986 Ford F250 with 6.9 diesel it does not run the motor is siezed, the truck ran last fall and was not run all winter the previous owner tried to start this past spring and it would not turn over. He then got strained financially so I bought the truck as is for 250 dollars. I pulled the drain plug and probably 2-3 cups of water came out of the engine before the oil came out. I tried pulling the truck with another truck and dumping the clutch in 1 and second gear it would not break loose, the truck just skided in higher gears the clutch will slip. I have pulled all injectors and filled the cylinders with Marvel Mystrey Oil and Sea Foam I also put some in the engine. I let the truck sit for 2 weeks and it still will not budge does anyone have any suggestions on how to break this engine loose if it is indeed possible.

Do you know why the truck was parked and was it broken when it was parked? Is there a big hole in the side of the block somewhere ? I would remove all the injectors and try to turn it by hand. Since you got water from the oil drain, I am guessing you will find water come out of one of the cylinders. If you cant get it to move by hand after removing the injectors, pull the heads. Probably rusted tight from the water. It seems like it will be a drawn out affair finding the problem.

The truck was in perfect running order when the truck was left to sit, this truck was not his every day driver and the truck was kept at his parents house he did not live where the truck was kept. There are no holes in the block.

pull the truck backwards and put it in 3rd or 4th. and then ull it forward and do the same, then backwards and forwards. it should loosen up. take all the glowplugs out of the engine first. and fill each cylinder full of marvel or use a mixture of automatic tranny fluid and diesel fuel. fill the cylinders through the glowplug holes then pull it back and forth back and forth, each time with the truck in 3rd or 4th gear don't slip the clutch too much.

it will blow oil and stuff everywhere when it starts turning, but i'd rather have a dirty truck than one that don't run. make sure to fill engine with clean oil before you do this and check to see if there is any more water in the crankcase. check it every day or two, it may be leaking from a head gasket or oil cooler into the oil pan. did the truck sit through a hard freeze? we have an old cat engine that when the water in the engine froze, the block busted all to hell. freeze plugs don't work...

I have pulled the glowplugs and put in marvel mystrey oil, sea foam and pb blaster and the motor still will not unsieze is the cause of the problem more that likely in the cylinders or a frozen bearing in the lowerer end.? Would a better way to break it loose be to put a breaker bar on the harmonic balancer and try to break it loose. the clutch tends to slip a little more than I would like when trying to break loose. I would like to think that I have tried everything before I tear into the engine.

i'd say the clutch is bad. and was the hood left open or the air cleaner left off??it shouldn't ever sieze hat bad just from sitting a year or two. unless they tried to use ether on it and it never started. it washed all the oil off the cylinders then when it sat, the cylinder walls got so rusty it won't run now. i have seen that hapen. its the cylinders that are rusted. not the bottom end. pull a head off and clean it up REAL good with sand paper and clean the cylinders real good with carb cleaner or something. then oil the hell out of the cylinders with some motor oil or 90 weight or something and try to turn it over again. sometimes you get lucky if you only do one side of the motor and it will turn over. if you get it to spinnin, put it back together, it should run. may burn a little oil and change the oil about 2 or 3 times after you get it runnin within the first 1000 miles and she will run for a long time. or put her in high gear and just rock it back and forth, back and forth. if you get it to move just a hare, you are doing REAL good, just gotta work it back and forth. the lower gears 1 and 2 aren't going to do you any good. just put it in 4th or 5th and rock it. it should come unstuck

maybe one of the cylinders had water in it, when he tried to crank it, bent a rod and now it wont turn. There isnt too many things that are that tight. Heck you can even get water out of a frog's butt and thats water tight.
