MF150 dropped power and started blowing smoke!!!

Sonny My diesel MF150 studdered a few days ago, dropped power, and started blowing a lot of grayish to black smoke. Things I've already done/discovered:

1. Fuel filter was nearly full of water, changed that.
2. Air filter had quite a bit of black soot in it,, blew it out, but it still smoked even with the air filter out.
3. Cracked each injector line to check if cylinder was firing... each line cause a definite change in RPM and running.

I'm out of ideas to try without taking things apart completely....

Thanks for any help.......

Also, How do I determine the year of my MF150? The serial number from the tag is "9A I88476".


Wayne Sounds to me like you have a bad head Gasket.
My MF-20c has had that trouble before Found blow out head gasket,in fact I just had the same thing happen again.

Sonny
Thanks.

But I discovered the truth yesterday. I rechecked each cylinder and found one actually not firing..... after disassembly, it turned out to be a broken intake valve.

I could use the proper torque settings for the head bolts for when I have to put it all back together, if you know that....
