I put a couple gallons in the gas tank..poured the sea foam in there then added 2 more gallons...**yes all 93 ocatane like always** and then poured a bottle in the crankcase**oil** and let it sit for about 15 minutes. I have let it run for thirty minutes straight and not a whisp of smoke. Nothing....My dad says he doubts theres carbon in there because I floor it everywhere I go and that it is all blown out first time I crank it up.! What do you guys think? Cost me 16 dollars. I was expecting some smoke here....Hmmm....I wont add it thru the brake booster line though because I am not familiar doing that and I cant risk hydrolocking it up. So do you guys think that there was no carbon or what?

 

I believe you only get the smoke show if you're doing the top end.

Are you planning an oil change real soon? Normally do one fairly soon after adding seafoam to the crankcase.

 

Do you think that I got it all cleaned out or no? Think I wasted my money and time? Thanks for the answer though!

 

No you didn't. It probably cleaned your bearings really good though. To clean the top end (combustion chambers, valves) you need to introduce the Seafoam into a running engine through an intake vacuum source. The back of the can explains this. If you didn't do it yet CHANGE YOUR OIL!
