How to free up a 59AB

[russcc]

The 59 engine sat in the barn for about ten years. Put it away with MMO in each spark plug hole, but neglected to pour some down the intake manifold. Looked up earlyier threads on this issue, and several promising ideas surfaced. I have heard the ATF or diesel fuel will free up engines. Any experiences with either one. I did spray Kroil in the cylinders and added more MMO. Poured MMO down the intake manifold. Any other suggestions ? Thank you Fordarners.

So is it frozen solid or can you get a little rotation?

All this takes time, The crank and pistons will move first, but stuck valves are a bit*h.

Use a parts washer syphon spray to apply the MMO. If mice got in and peed on the tappets it may never turn. G.M.

My spare 221 sat a long time and stuck too. When I took out the spark plugs a roach ran out! !#$@_)*()(*#! Must have come in an open exhaust valve, because I didn't cap the exhaust manifold.
It's soaking now, but Ill probably have to pull at least one head.

You will probably have to pull the intake manifold and get to the valve assemblys. Squirt a 50-50 mixture of ATF and Acetone all around them and keep them wet. I put a breaker bar on the crankshaft counterclockwise and fashened a jack under the bar end leaving it under pressure from the engine weight. After a couple of days pressure mine broke loose by itself. Oh happy day.

Good suggestions. Thank you. The stuck valve train sound like a good place to start. The ATF & Acetone, will give that a try and report back.

This subject has come up recently and I just got this email thought it pretty interesting."Machinist's Workshop" recently

published information on various penetrating oils. The
magazine reports they tested these products for "break out
"torque" on rusted nuts and bolts. A subjective test was made of popular penetrating oils, with
the unit of merit being the torque required to remove the nut from a
"scientifically rusted" bolt.
Average
torque load to loosen nut:
No Oil used ........................516 foot pounds
WD-40
..................... ........238 foot pounds
PB
Blaster .........................214 foot pounds
Liquid
Wrench ......................127 foot pounds
Kano
Kroil .........................106 foot pounds
ATF/Acetone mix..................... 53 foot pounds

The
ATF/Acetone mix is a "home brew" mix of 50/50 automatic transmission fluid and acetone. Note this "home brew" released bolts better than any commercial product in this
one particular test. Our local machinist group mixed up a batch, and we all now use
it with equally good results. Note also that Liquid Wrench is almost as
good as Kroil for 20% of the price.
ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a 50/50 mix. ATF = Any
type of Automatic Transmission Fluid

i had seen that "report" several years ago when working on a 78 corvette project. i have been in couch over the past years with several folks who swear by that as the best penetrating "oil" solution ever. it is certainly inexpensive enough and always seems to do the job. one of the keys to the whole process is patience. let the mixture work and give it plenty of time to do so. it is penetrating "oil" not instant relief for the problem. more damage can be done by impatience and torque than time.
