has anyone tried putting seafoam in the mini?
I've tried using it with fuel injected cars but i never use it on carb cars, but i assume they work the same?
where should i put seafoam on the carb? I found a vacuum port after the throttle plate on the carb, should i just put the seafoam in there or should i take out the air filter and put it through there?

thanks.

 

My 2 cents .... I wouldn't .... I've seen some SeaFoam horror stories especially over on the Miata sites where people are playing with cars a bit older than MINI...but certainly not as old as most Mini....

I had good success achieving what I think you are looking for doing a partial carb disassembly and cleaning. With the carb still on the car, take the three screws off of the 'pot' and it can be removed along with the needle and the piston & spring. I found a lot of varnish on the spring and the inside of the pot causing the piston to hang up. A good dose of carb cleaner and a few minutes with a brush cleaned things up nicely. I verified the needle was straight and seated well, used the carb cleaner on everything I could get to in and around the carb and put it back together with a noticable improvement in response (remember to refill the pot oil chamber) using the lifter I could tell the pot was moving freely and now that's on my monthly checks. True tho, this only cleaned the carb...no manifold deposits if that's on your hit list.

Some folks just dump seafoam in the gas....our tanks are so small I think I'd use about 1/3 a can IF I were going to try it....

 

Dumping seafoam straight into the intake really doesn't do anything. All of the smoke you see when you do that is just the oil in the seafoam burning off. It's got pretty much the same junk that regular fuel injector cleaners have in them plus the oil.

 

the shock of cold fluid in the combustion chamber can be acheived using plain water . but sea foam is reportedly better . hold it at about 2000 rpm and slowly pour into carb . the steam created cleans the valves etc. of deposits which cause detonation . piston deposits can effectively bring your compression up causing pinging . i just throw a bottle in the tank now and then . don't have a classic but internal is internal .

 

I've heard nothing but good things about seafoam.

It definetly works, cleans out your engine, and improves response dramatically.

I'd say put some in your tank and oil, run the car at about 2500 rpm for 5 minutes, then take the car for a drive keeping it in the higher rpms, then go home and change the oil

 

where do you pour the sea foam into if you have a 2007 cooper s?

 

This is the classic mini forum so you may get better results posting somewhere else. I would not put seafoam in your new cars intake. It's meant to clean out carbon deposit which your car should not really have too much of yet. Just run some regular injector cleaner through your tank or put the seafoam in the tank. Theres better stuff than seafoam out there anyway.

 

what would you suggest instead of sea foam? And where might I pour it in?

 

I use Chevron Techron in my 06 cooper s. Its in a black bottle and claims to be synthetic. It seems to work well on clearing up the rough cold starts. If that's what your after. Put it in the gas tank just before you pump a tank into it.

When you see pictures of smoke after someone puts seafoam directly into the intake the white smoke is just the seafoam burning off. If you actually accomplished anything by doing this the exhaust would be extremely carboned and there would be a spot of carbon soot on the ground behind the exhaust.

Seafoam is just glorified fuel injector cleaner. It's no miracle product.
