My boy put some in my vacuum line thing and I can only see it idles smoother? But what else and where else am I suppose to use it on? Seen videos where ppl put it in their gas tank. Any one have experience?

I've seafoamed all of my cars (I'm up to 6) and it seems to work great! Take 1/3 of the can and clean your induction (vacuum lines), take one third and put it in your gas tank, and take the last 1/3 and put it in your oil (Be careful with that one, only do it if your oil is BLACK and only dont put too many miles on it while its still in your oil. ~100). Its best use however, is the induction cleaning. Usually has a noticeable different in idle. The way I do it is probably not recommended, but I just take a cup with SF in it, and stick a vacuum line in it (obviously, dont fully submerge the line, or your engine wont get enough air), and play with the throttle butterfly so you dont stall the car. Your neighborhood WILL fill with smoke, and your check engine light will most likely come on, just reset it when youre done. Once most of the smoke has cleared, shut the car off (disconnect the battery if you dont have something to reset the engine light, if it came on), and start it up again and hit vtec a couple times, you should see a difference.

 

Which vacuum line?

 

Which vacuum line?

 

the PCV hose

 

I've always used the one coming out of the brake booster, but I havent checked how accessible that is on an S. Might wanna try the PVC hose like big red said

 

So you guys wouldnt recommend putting it in the hose that connets to the intake tube?

 

I have no idea if it would work or not. My guess is that if it has a vacuum and it leads to the engine, it should do the job.

 

i was told recently when i was winterizing my car that i should use seafoam instead of stabil while storing my car.. i didn't see anything on the container that said said it was a substitute for stabil.. any thoughts?
