    Crashed in water

    Last year I was flying my Cessna 182 4 stroke over the water when one the battery's in my TX came loose which resulted in a crash into the river. Now a year later I am trying to bring the engine back to life with no success. I have checked the glow plug but I cannot get this plane to fire. Does anyone have any suggestions on bringing this engine back to life for this years flying season?

    Only thing to do is completely disassemble the engine and clean it out. You will most likely need new bearings. Oil it up and put it back together with a new glow plug and give it a whirl.

    True. If you didn't start, and run the engine after you got it out of the water and subsequently oiled it up , chances are good the bearings are rusted Especially if it's a Saito !

    RE: Crashed in water

    Another thing to look at (after checking the above) would be valves. I'm thinking that they are rusted in place. Frank is right, disassemble the engine. Take the head off and see if the valves move. If so, you may have a fighting chance of saving the engine.

    If the engine wasn't run out as Brian suggested, it may just be a giant chunk of rust inside. There is only one way to find out for sure. Personally, I'd give it a go. I'm betting that this engine can be brought back from the dead, but not just by filling it with fuel and trying to get it to fire. You may be doing more damage to it if the valves are rusted/stuck.

    Just my $.02

    RE: Crashed in water

    You have nothing to loose so try the crock pot method. Get a crock pot from a thrift store(couple dollars) and get some antifreeze. Pour antifreeze into the pot a little more than halfway and fill it the rest of the way with water. Remove the carb and rubber "O" rings and set them aside. Remove the backplate , valve covers, glow plug and muffler and remove any gaskets. Turn the pot on low. Put the engine into the pot along with the metal parts and muffler (but not the carb) and make sure everything is covered with antifreeze. Let it cook for 8 hours and remove the engine and slowly rotate it a turn or two and put it back in and let it go another 8 hours. Then you can remove the parts and clean them up a bit with a brass brush or tooth brush. Oil the engine parts and reassemble it and oil it up again.
    You may get lucky and get a few runs out of it before having to change out the bearings.

    RE: Crashed in water

    Hi Brian,

    I've never heard of adding water to the anti-freeze in the crock pot. I always use mine straight. Have you tried it both ways? What was your opinion of the difference??

    RE: Crashed in water

    Hi Bob,
    Yes I did. It seems to make more steam with some water(1/4-1/3) added. You can tell the water "boils" off as the level goes down in the pot. Not sure which way is the best but I have been adding water when I "cook" an engine.

    Hi Brian,

    I'll give that a try the next time that I do an engine. Thanks for the tip,
