Good deal, the more smoke the better. I am not sure how many miles you have, but probably a lot of carbon buildup on those valves! Remember, if you put it in your oil to be sure to change the oil soon. Glad it worked out!

 

In all actuality it allowed me to find a leak in my exhaust manifold lol. Smoke started pouring out from up under the hood. Looks like where the runners meet at the flange that connect to the turbo there is a crack i couldn't see..

 

haha^^^

 

just seafoamed my 2004 ralliart it works ....ideling is great and startups without delay also my engine sounds quieter too.

 

 

For many years, shops use this or Wynn's when performing a valve cleaning service. Completely safe. Did many a Supra turbo at the dealership where my cousin worked. Buy or make a metering connection so the car doesn't stall when you do this.
To make a metering connection all you need is some vacuum line and a needle that is used when you air up a football. Attach needle to vacuum line and drop into the can.
