Well I didn't try the trans fluid yet but going through my old chemicals I found a can and a half of Ford Motorcraft "Tune-up Cleaner" which is similar I think to the Mopar combustion chamber cleaner. Ran both cans through and got a little smoke nothing too wild. Checked with the borescope after, the tops of the pistons are probably 75% clear but I can see parts of the combustion chamber on the head are still a bit thick. Also with the exhaust vlve open its pretty chunky in the passage for what I could see. m Still wants to ping a but under WOT but not as bad. Maybe another dose of something and a good hour on the highway might sort it out.
