I've always had some tapping & ticking from my hemi. So this morning, Before i changed the oil, i ran 3/4 of a can of seafoam in the oil, and went for 20 min drive. The ticking & clicking is gone. I drained the oil, and put new in, and the motor runs much more smooth and quieter.

I wish i would have taken a video of the sound before and after.

Anyways. I would recommend running a can before your oil change.

 

i've always heard good things about this stuff.. I guess I might have to try it sometime.

 

I used some last time AFTER I changed the oil.....(stupid "friend") anyways after a few hundred miles I changed the oil again just to get clean fresh oil in there. The oil (M1 synthetic) came out BLACK. Since then my oil has been pretty clean and no problems. It cleaned 'er out well.

 

yep we got some seafoam in at work to try in a our army vehicles... put that stuff in every-- diesel gas oil lol anything and everything and it worked great for internal cleaning.
Also in my own hemi i use this with every oil change-along with some Lucas oil stabilizer
Wynn's Engine Tune-Up- it gets rid of that clicking ticking noise

 

Interesting. I've not heard of it fixing a tic. I only use Seafoam about once a year. Do the full treatment: Brake booster, fuel tank, and crankcase.

 

Seafoam saved my Riding Mower,good stuff!
