Hey guys, I know there's numerous threads about seafoam (don't care about your opinion on it, just tryin it first before water/atf). Just took my car out of the garage today after it was stored over winter and I'm gonna seafoam it in hopes of clearing out carbon to give me some side sealage again. I'm wondering which vac line leads to both rotors. I read that one of the ones by the UIM, does anybody care to point out which one?

Or should I not even bother with sucking it up with a vac line? (read that it doesn't matter somewhere before, just gives the smokey effect).

 

The one near the BAC should work. I believe it feeds the Air Bypass Solenoid valve.

 

I have a MAP sensor so I put it down the intake after i take off the intercooler :P
