   Good Soak For Rings In an Engine That's Been Sitting A Long Time???   
      
   When I was a kid everybody said to dump a table spoon of Marvel Mystery   
   Oil down each spark plug hole amd let it set for a few days to reduce   
   the risk of cracking a ring when you start trying to move the engine.   
      
   From what I've heard and read they changed the formula of the snake oil   
   and is not so good anymore. I don't know.   
      
   Yesterday I heard a new one. Dump a mix of ATF and acetone in, and put   
   the spark plug back so the acetone will force the ATF through the rings   
   with pressure as it turns to vapor. I've never heard that one before. I   
   have some reservations.   
      
   I've got a 42 GPW (that was my dads) Jeep with a newer M38 Jeep engine   
   that eventually I'd like to sell. Its been parked for 40 years so there   
   will certainly be some tendency for the rings to stick. I'd prefer to   
   sell as is and let somebody more expert than me deal with it, but I see   
   no reason not to do little things to help that happen as time permits.   
   Eventually being able to get compression on all cylinders might help...   
   unless its bad of course.   
      
   Anyway I'd like to hear what you guys know or have heard about soaking   
   the rings in a sitting engine before trying to turn it over.

   ATF + acetone came out best. I've had good results quickly from Kroil but   
   not on a steel bolt in cast aluminum. Those threads didn't break free after   
   being drilled out and tapped the same size.   
      
   "A study done by Machinist's Workshop magazine in their April 2007 issue   
   looked at different penetrating oils to see which one did the best job of   
   removing a rusted bolt by measuring the pounds of torque required to loosen   
   the bolt once treated. If the study was scientifically accurate, it turns   
   out a home brew works best!   
   Here's the summary of the test results:   
      
   Penetrating oil ..... Average load   
      
   None ...................... 516 pounds   
   WD-40 ................... 238 pounds   
   PB Blaster .............. 214 pounds   
   Liquid Wrench ...... 127 pounds   
   Kano Kroil ............. 106 pounds   
   ATF-Acetone mix....53 pounds"   
      
   You might be able to inspect the cylinders with a fiber cam. This one gives   
   me a good sharp image and can inspect bores almost down to 5.5mm, most have   
   8mm camera heads.
