Shagy Posted May 26, 2011 Report Share Posted May 26, 2011 What would you try and use to unstick a motor prior to a tear down and rebuild? On friend suggested marvels mystery oil. Thought I'd ask the general population. Quote Link to comment
izzo Posted May 26, 2011 Report Share Posted May 26, 2011 I remember reading this in another thread. Stove oil, motor oil etc. Search for it, still might come up. Quote Link to comment

Shagy Posted May 26, 2011 Author Report Share Posted May 26, 2011 see I thought ATF also. I'm going to drain the oil and thought about filling the motor with ATF...just give it a good soaking for a week. I've been reading stuff on the Marvel Oil forum...I think I might actually try it. been reading stuff like this ... http://www.marvelmysteryoil.com/index.php/forums/viewthread/469/ Quote Link to comment
king bee66 Posted May 26, 2011 Report Share Posted May 26, 2011 mystery oil is good stuff, go with that. ive also heard diesel works but have never tried it myself Quote Link to comment
NOTES... Posted May 26, 2011 Report Share Posted May 26, 2011 Ive used ATF on a motor sitting for 5 years and it was awesome... Quote Link to comment
hang_510 Posted May 26, 2011 Report Share Posted May 26, 2011 mystery oil is good stuff, go with that. agreed! Quote Link to comment
MicroMachinery Posted May 27, 2011 Report Share Posted May 27, 2011 My 521 hadn't been run in 15 years. A couple spoonfuls of ATF into each spark plug hole, and a few days waiting time did the trick. Quote Link to comment
motavated Posted May 27, 2011 Report Share Posted May 27, 2011 Maybe a combination off all mentioned? Quote Link to comment
Dirk Diggler Posted May 27, 2011 Report Share Posted May 27, 2011 Pre 73 Japanese cars were designed to use whale fat as a lubricant in the trans and engine, you can get imitation whale oil that will work better then atf. Diesel oil is also more aggressive as a detergent than regular oil. Quote Link to comment
Farmer Joe Posted June 3, 2011 Report Share Posted June 3, 2011 man ive heard of alot... marvels mystery oil, tranny fluid, diesel fuel, allll kinds of stuff.. i worked on a dodge 440 motor that had been sitting for 12 years.. filled up the cylinders with tranny fluid and forgot about it for a week. hooked up a battery to it, turned it over with the plugs out, and first crank it spun over like it was never stuck..

herculesinwyoming Posted June 4, 2011 Report Share Posted June 4, 2011 any luck on your project? Quote Link to comment
Shagy Posted June 6, 2011 Author Report Share Posted June 6, 2011 I was able to put some MMO in it yesterday...freaking 7/8" spark plugs and all I had (I thought was a 3/4")..then I found my 21mm socket...I pumped some in there and will let it sit for a few days then do it again. This weekend I'll try to turn the motor over. If I can I'll also be pulling the intake manifold off and seeing what it looks like, I hope the carb stopped most of the mouse crap.

Shagy Posted June 13, 2011 Author Report Share Posted June 13, 2011 Well today I went to go see if the motor would move.....tried turning it clockwise...nothing. thought. I really don't want to snap the crank bolt. Tried turning it counter clockwise just thinking that I was going to loosen the crank bolt. I frlt something move....I didn't see anything though. So tried CW again and watched the pulley....it moved!!!! Then stopped :-( son of a bitch.... So went CCW and made one full rotation untill it stopped again then went CW with it and it never stopped again!! Pulled the VC off and poured MMO over everything and continued to turn the motor by hand. There is a bunch of stuff on top of the pistons from what I can tell. I looked @ the carb and I need to vaccum the mouse droppin out so they don't get in the motor. I kind of felt like hooking my jump box up and cranking the motor to blow out the cylinders....but didn't..... After sitting for 31 years, she's one step closer to running.. Quote Link to comment
NOTES... Posted June 13, 2011 Report Share Posted June 13, 2011 Why didnt u try ATF? Quote Link to comment
Suspect Posted June 13, 2011 Report Share Posted June 13, 2011 I used Kerosine which is like Diesel fuel getting a moped motor unstuck. Quote Link to comment
Shagy Posted June 13, 2011 Author Report Share Posted June 13, 2011 Figured I'd try the MMO read lots of threads on it. ATF would have been the 2nd step... Quote Link to comment
