Stuck Six...


Got a stuck 261....that was sitting for 30 years.

Going to dose the old dear......

I've used ATF and or  diesel fuel...before.....Somebody said mix them.....

How about Move-it  penetrating oil...or Seafoam?

Any input is appreciated

Never tried it but I've always been told the ATF/Diesel mix is the secret potion!

Yes the Diesel ATF solution worked in my experience.

I'll second that!!! Have used ATF & diesel mix on a few engines to get them to free up. After giving cylinders a good shot I try and put a load on crank pulley by using a jack and socket & breaker bar & let it sit with torque applied to break it free.

Pete, how much time should you allow to let the secret potion do its job before applying a load to try and unstick the engine?  Do it immediately?

Like I said dose up the cylinders, then apply pressure to crank bolt & walk away for 24 hrs  You can let the cars weight work on breaker bar & socket with axle stand on bar or use a jack!!! with pressure applied. Not a guarantee it will work 100% of the time, but worth a shot. Did a 57 Olds this way & it broke free.

Ok.....drugs...have been administered.....

Not being very familiar with this engine....I'm kinda scratching my head...as to how I can roll it over....

Are there some threaded bolt holes in crank damper?

This one has an Iron glide.......and I don't recall seeing a cover...to expose ring gear...

Can you put a socket on the crank hub bolt?

I have put a socket on the generator pulley nut to try to roll the engine. Sometimes they move a bit and you could rock it back and forth. I have also removed the starter to pry the ring gear. Time is your friend. Unless its really rusty on the cylinder walls it should free up. I did get one running that sat in a barn for twenty years running after adding diesel fuel and trans fluid to the cylinders. I let it sit for a couple of weeks. If the spark plugs were really rusty when you pulled them out you probably will need to pull the engine apart.

Good call....on starter /ring gear access...

 

Generator and brackets were robbed....but engine was covered with hood....plugs came out nice   and no sign of water/rust....so hopefully it will break free..

I will let the brew "cook"...for 2 weeks......and give it a whirl..

 

Had a stuck Pontiac 400...years ago......Soaked the rings   let it sit.....

Couldn't move it with a breaker bar on the crank.....

 

I installed a battery.....hit the key....and the starter did the job......

 

It actually ran pretty good.....after I fussed with it...
