Full can in a full tank of fuel, half a can in the crank, have in the intake, change the oil when it's time to refuel... happy seafoaming!

 

ive done seafoam in my audi a4 with high mileage also.. the first few days after seafoam my car idle REALLY smooth it was like the car wasnt even on.. but later on my car started to rough idle again.. idk maybe its from the AC thats turned on (Gotta love Florida right?). What i did was 1/3 in intake, 1/3 in crank and 1/3 in fuel.. change your oil after and pour some gas in so the seafoam will mix with the gas

 

Thanks for the link meloman, that is the same DIY that I had printed...

So I seafoamed last night.... smoked out the neighborhood. I ran half through the front vacuum line and the other half through the rear vacuum line, I sat in the car and held the rpms and my brother controlled the amount of seafoam it was using. I shut it down for 15 minutes then ran it hard. It smoked for about 5 minutes of driving and that was it. I don't really feel much of a difference, and I wasn't too hopeful... just wanted to try it out. I would have to say that the idle is slightly smoother and the accelleration is a little smoother as well. We'll see if anything changes. I left the plugs alone for now, didn't want to replace them with the engine hot. I replace them every oil change, so they will be done in a couple thousand miles.... I will pull one out for an inspection this weekend though and that might change my mind.

 

Can someone tell me what the vaccuum line on the front of the intake connects too? I am talking about the one closest to the front of the car. Just got this car a week ago and was getting ready to seafoam it when I noticed that the vacuum line isnt connected to anything just the intake itself. I cant find where it leads to. Thanks

 

It should be hooked up the the diverter valve.

I have seafoamed the **** out of my car, and to be honest, it hasn't really made a huge difference. If anything, it made my mileage worse.

I thought the seafoam would help remove carbon or sludge build up on my passenger side head, but it didn't.

From what I hear... Mopar CCC is WAY WAY WAY WAY better than seafoam. Mopar guarantee's 100% that you will not get hydrolock, and the foam does a better job of expanding and seeping into every crevice.
