What does "tied up" mean to you? Are you referring in some way to a turkey?
Aft - Are you sure you don't mean abaft?
mar·i·nate
[ˈmerəˌnāt]
VERB
marinating (present participle)
soak (meat, fish, or other food) in a marinade:
"the beef was marinated in red wine vinegar"
synonyms: steep · soak · souse · immerse · marinade · bathe
(of food) undergo soaking in a marinade.
Important thing is to be patient, it didn't get stuck overnight, so it can take weeks or months to come unglued. Try it every few days or so with a breaker bar on the crank bolt.
Ok so this is a method that was told to me by friends who have turned hundreds of old cars. There method is to connect radiator hoses off stuck motor to a running motor radiator. Meaning.. they are making a closed heat loop to get stuck motor up to a running temp. This is accomplished by the good running motors water pump, circulating the hot water. They say they have had very good luck with this method getting the motor to free up. I have not tried it. Heating something up is a good way to get something loose.
Supposedly the pistons are rusted to the cylinder walls? In this case hot water from an other engine would do not much. But I like that idea, and it will certainly help the ATF in penetrating. Mixing some kerosene or diesel and some acetone to the ATF would help as well. The acetone can mix with water, if water got into the combustion chamber and would work wonders.
Initial post will less than 50 charakters is a little brief, though.
LOL. Sorry, I guess I should have sobered up before starting a thread. In the Blizzard of 78 the engine got snow/water in the intake. At has not turned since then. My Uncle put it in the barn(at little late) after the storm and it has sat there in the dry barn ever since. It was a good engine before that(plenty of power, no oil burning and no leaks) from what I remember. It has a mixture of Marvels and ATF in each cylinder at present.
Thanks Titus, I will try the acetone trick.
Happy Thanksgiving
I have had engines where I have had to literally chisel out the pistons because of years of rusty neglect. Don't mean to rain on your parade, but this is a possibility now than more history has been revealed. More than likely the cylinders are very badly pitted, and the pistons and rings are junk. I would just cut to the chase and pull the head.
Thanks Mixer Man. My Uncle said that he poured oil in the combustion chambers not long after the water got in. But that was 40 years ago.
I won't open it up until Spring, so I guess the soaking will continue for now.
Seems to me you’d do well to start lining up a replacement 215, just in case yours can’t be saved. Or at least a donor engine to combine with parts of your own that can be saved. Several of us probably have extras. I know that a member there near you in OH bought a NOS block a while back and may still have it available. I have what’s left of a long block engine that I’ve picked parts from if it’d be helpful. It’s a long block with all internals intact. I’ve not had it apart so don’t know the condition of its guts.
