I've sea foamed a few cars in the past and always had plenty of smoke. Just tried on my Disco to hunt for exhaust leaks and it didn't smoke.. none zip zilch nada... What gives?

Put it in through the brake booster vacuum port on the manifold.,..

 

You did 1/2 to 3/4 of the bottle on a already warm engine, then let it sit 10-15min and restarted it and no smoke?

 

Did you put it in slowly, like 3 minutes to the bottle, shut it down, and then wait 20-30 minutes to go for a ride? Worked for me, but only smoked for 2 miles or so.....

 

Sorry I posted on top of you Best. We were answering at the same time!

 

I used some tubing with spray stick from a can of wd40 as the final size to draw from the can and sucked down half can in about 90 seconds.

Motor was not hot but I figured I'd still get some smoke.

PS Best 4x4 check your PM's

 

If it doesn’t sit for 10-20min after you run 1/2 to 3/4 of a can thru it = I don’t it will smoke. If you just let it run without sitting the foam doesn’t have time to do anything. It would be more like adding it to your gas tank.

 

I ran two cans of sea foam. First try I did not follow instructions. Little to no smoke. Second time I did exactly what the instructions said and crop dusted the neighborhood

 

I was told that tests were done with sea foam that even on brand new cars with 0 km they performed the treatment and it smoked even in brand new lawnmowers never used it still smoked like crazy

 

I emptied a whole Seafoam can into the tank and then add another 3/4 of a can into the intake on a warm engine. Waited 20-30 minutes and ran it like I stole it on the freeway. Ole Myrtle smoked like a carton of Winstons for a couple of miles.

Save the cans to show the police in case you get stopped by them. Just sayin...
