I would like to put Seafoam into the intake manifold but I'm not sure which vacuum tube to use and I don't want to put it in somewhere it shouldn't. There's some other threads of folks here putting seafoam into their manifold with success.

The two tubes that looked most logical are the "Part Load Breather" tube or the tube that runs from the master cylinder... I presume it's the brake boost vacuum tube. Both look like they're going into the manifold.

My friend with a BMW E36 used the brake boost tube and worked great but I looked at the Mini and I'm not sure how to access or disconnect the brake boost vacuum tube to suck up the Seafoam. Alternatively, the Part Load Breather tube looks easy to use to suck up the Seafoam but I'm not sure if this is the right pathway into the manifold.

Anyone have any thoughts, suggestions or solutions?

thanks!

 

I put it through the brake booster on my Jeep as well. I am interested to see where people have sucked it down on the mini.

What year is your car and how many miles? Are you experiencing a rough idle or decreased gas mileage?

 

I just put it in my gas tank every 5K (oil change).

 

I put 1/3 of a can of Seafoam into my fuel with a full tank already. I would like to put the rest in the intake and oil.

I have 72k miles on the car and no rough idle. Didn't buy the car new and I've been averaging 26mpg in mixed driving but I gotta think it can do better.

 

Cooper or cooper S? That sounds about right for and S
