I just bought a 93 Accord EX-R with approx 131,000 miles and I want to seafoam it.

I used seafoam before on my MR2 and that sonuvabitch had 245000 miles, and it worked great. So Im not concerned about dislodging crap.

Anyways which vaccum line on this 4th gen accord do I need to seafoam? can anyone direct my to a picture, that would be fantastick. Thanks.

 

use the line Comming from the brake booster to the intake manifold

Or use the line from the PCV valve to the the intake manifold

 

brake booster line, just after the check valve.

don't use seafoam, your bearing and all the metal in your motor will thank you for that

 

i used it once. didn't really seem to help my cause. i guess it wasn't carbon related like i thought. but i have heard alot of pros and cons. you can add that stuff to two inputs as well besides your vacuum line.

hey ima7head. dude you must live hondatech,lol. You trying to reach the 100k mark
