Marvel Mystery Oil?
#21
I tried a dose (can't remember the exact amount) of MMO in the oil and let it run for 3,000 miles with no results for the Hemi tick. On the last oil change I put Mobile1 0w-30 Synthetic that seemed to quiet it down a little but the tick is still there. If it is due to short rods why would it all of a sudden appear?

You can get it at a local parts store. Red bottle, black/red label.
IMO it's kind of like Seafoam. I run Seafoam through the brake booster to clean things out and also the gas tank for fuel lines/injectors. MMO is good for running in the oil, it can fix dried out seals and cleans the inside well. You could also run it through the fuel lines as well.

I used this stuff in my Olds 98 once. It was a 307 with a little over 100k and excellent cylinder pressure. I thought I would try it to help clean the engine out. Well I added it and drove around for a good while and then started getting a knock. Well the knock grew worse and by the time I get it home it was so bad it would hardly stay running. I pulled the engine and pulled the pan first. After removing the main caps and then the crankshart I found I spun to main bearings and literally destroyed the crank. I flipped it back over and tore down the top of the engine only to find all that stuff that Mystery Oil "cleaned" deposited in the valley of the block and blocked all the oil drainage holes that go back down to the pan and pump. So all my oil ended on the top side of the engine with none is the pan resulting in the spinning of 2 main bearings. I will NEVER use it again.
