Hate to necropost, and seafoam has been beaten to death, so i won't start a new thread... BUT!
I purchased my VX yesterday, and it's the first Honda I've had. I'll be trying a seafoam treatment, and was wondering which line is "best" to run it through (i.e., a relatively even distribution across all cylinders.) Through the brake booster line? Passenger side air vent? CD player slot?
alot of people dont recommend the brake booster cuz of its large size. if you're not careful you can hydro lock. choose a small vaccum line in front of the throttle body, but before any cylinder. then it'll go through the whole thing safely.
On their website it says: "Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time." That leaves me a bit worried that this will blow gunk down the pipe that will clog up the catalytic converter, which is a pretty expensive part, from what I hear.
