Ok so i decided to try this seafoam thing on my 94 accord f22 non vtec and i did everything step by step, and theres supposed to be a butt load of smoke coming out of the exhaust from what ive seen in videos but when i did it theres very little and theres smoke coming from the headers it seems like but also very little? Anyone got some info on this?

 

What steps did you do?

How much of the can got "sucked" into the engine?

Smoke from the "header" means you have a leak...something you need to address. If the exhaust system is "sealed" all smoke should go out the tail pipe at the rear of the car.

 

i put about 2/3 in the engine then 1/3 in the gas tank, and how would i address the leak in the headers? And regardless of the leak it didnt seem big enough to not allow basically any smoke go thru the tail pipe...
Steps, vacuum hose while car was on, then thru engine head, then gas tank.
