Engine Drivetrain 2nd Gen Most liked posts in thread: How-To Seafoam Treatment R55/R56

In its gaseous state (not the same as vaporized mist) the product can no longer soak carbon deposits to revert them back to a liquid state. As you say the product is petroleum based, that's why smoke is produced after the soaking period per application instructions, oil is burning.

Nothing is magically formed in a catch can, it is merely gas after a phase shift, the greatest proportion of which is water, followed by oil, and tiny amounts of unburned fuel. Some of the water is condensation formed by the cool CC cannister being heated, and not an engine expulsion.

 

Why not just use a Good Throttle body cleaner?? Does the same thing and is made to do the same thing it cleans the carbon out of the top end of the engine

 

Glad to see you posting on MA!

 

Keeps the mosquito population in check too I bet.

 

Cool! Can you put the seafoam in the same spot for an R53 with similar results?

Thanks,

Love the vid!

only thing I do different is if I have a second helper, I have them revving the car while I meter the seafoam in. I have them kill the ignition while I putting liquid in so that it's really soaked when it sits for a while.

There are tons of products that do pretty much the same thing. They're all some nasty petroleum distillates that have some pretty good capability to dissolve all this crap left behind. Most people tend to stay with whatever brand they found that worked. I buy the stuff about 6 bottles at a time to get a break on price...

Great vid!

Thanks for the post. The video is very helpful.

 

Ok.. so why does it smoke so much after? How long does that last?

 

The smoke

is from the stuff burning up when you start the car after injestion. It lasts a couple minutes tops...

It can be quite the "show".....

Anyway, Sea Foam and other products like it work very, very well.

The old biddies in my HOA would have cow, they already make it known my comings and goings are heard.

 

Why are you changing the oil so frequently? I thought these babies were go to for 15k between changes?

 

3k is very aggressive.

I'm in the once a year camp or the 10-12 k miles. Really, if you want to know what's up, get your oil tested for additive breakdown and contaminants.

On my new R56, I did my first oil change at 500 miles. With the break-in period and figuring all the sliding metal parts in the new engine were just getting to know each other, changing the oil myself was pretty cheap. Since then I'm changing the oil at 5,000 miles with European Castrol Syntec, SAE 0W-30.

 

I did a Seafoam treatment on my MINI about 3 weeks ago. Not sure if I borked it as I did not get any smoke from my application. Did an oil change and switched over to RP at the same time. Between the two, in the three tanks of gas I've gone through since then I've since an improvement of about 2 mpg.

 

Just did seafoam for the first time. No smoke at all, I was surprised.

Oxyblue, I know this is for second Gen's but you said you had done it on your R53 as well? You just add it to the gray line under the IC?? That line runs from the PCV valve to the intake manifold? or to the supercharger inlet tube?? I always thought it went to the supercharger inlet tube. I've got a can of it and a can of deep creep to clean out the throttle body, so I'm just trying to confirm where to add it to.

Thanks,
Steve

 

anybody got any ideas?? is it safe to run the seafoam through the supercharger vanes?? I know this is 2nd gen but I saw it come up so that's why I'm asking

thanks
Steve

 

I personally wouldnt. I dont know if it would actually harm anything but going post would be the best way in my opinion.
