Try mixing some ATF with the soaking diesel. Let sit a week or so. Then try it again. Good luck-glen
You have a wonderful day. Best wishes. Deas Plant.
Hi, Jbayer.
If the above doesn't work, try putting some Pepsi-Cola in the bores and ONLY leave it for 24 hours AT MOST. Then flush it out with diesel fuel or similar and compressed air. Be careful when using the air that you have protective clothing and GOOD eye protection - like sealed goggles. A good long blowing nozzle for the air is a good idea too.
If that doesn't get it freed up, look at removing the heads and doing some more drastic surgery.
Hope this helps.
Why not pull the valve covers and see if you have stuck valves. If it moves a little the pistons may not be seized. You can remove the rocker assys and see if it turns over. You can probably free up the valves one at a time.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
