The booster line is not the main flow path of air into the engine. The throttle body is. Dribbling it down through the throttle body will give you the most even distribution into the engine.

And about the ATF comment... Use it if you think it is "the same thing"...

 

I have always used ATF in the past. I am not sure if seafoam is better. I have fouled a plug with ATF before.

 

I would think that using ATF would kill an O2 sensor as well. seafoam is sensor safe.

 

This might be asking too much, but could someone make a
"tutorial" vid of seafoaming a 2nd gen? If not, that's cool too, I'm just curious.

 

From what I understand the best way to do the seafoam treatment to a carbureted engine is to dribble it in through the primaries. Does it help or just make it more a pain in the **** to put it in a spray bottle first?

Second. With my oily plug issue could it possibly cure/exacerbate the problem?
