First get all of your supplies together, i use one foot of 3/8 fuel line, it is sold by the foot and this is the perfect amount for the job, i used a pyrex glass to measure out 1/3 of an pint, i also used a small dish to feed only a small amount at a time. (i did this at my moms place so dishware was all that was availble)


now find the vacuum line going into the manifold right after the throttle body.


turn the red clip so you can see were the two ends seperate, then push down on the clip to remove it.


pull the vacuum line off to reveal the nipple where you will attach the 3/8 fuel line.


now attach the vacuum hose, feed it upwards out of the engine bay, everything is near the fan so be CAUTIOUS.



now feed the seafoam into the hose, SLOWLY.


in between feeding SMALL amounts of the seafoam into the engine, cover the vacuum hose with your thumb to allow the engine to return to a normal idle, thus more effectively sucking the seafoam into the cylinders.


after feeding all of the seafoam, turn off the engine and allow it to soak for 10 minutes, turn your engine on and enjoy the smoke.

some tips, remember to feed it SLOWLY this stuff can hydrolock your engine if your not careful

turn off the engine when your detaching/attaching the vacuum hose, it is near the fan so be careful

when you reattach the red clip push it on from the top then wiggle it till it is in it's correct place.

good luck

I just got my sea foam during lunch today $6.99...

I sea foamed it at night so the smoke wouldn't bother anyone.

WOW I put the sea foam in an 8oz water bottle (The short type) and then stuck the vacuum tube NEAR the opening of the bottle. Well the suction from the intake manifold created this vortex in the water bottle and I was able to slowly feed the sea foam into my car as it idled. Boy was the idle choppy, plus I threw a CEL which I had to reset with my scangauge. The CEL hasn't come back which is good. :)

Anyways, a huge cloud of thick white smoke came out my car for 5 minutes after sea foaming it. I decided not to put the rest of the bottle in my gas tank, but instead I put Shell V-power.

I'll save the other 8oz of sea foam to do my wife's car or something.

I felt afraid to drive the car hard because there was sea foam in the intake manifold that I didn't want to hydrolock or anything like that... But once the smoke was gone, I had more confidence to drive it a little more spirited.

Anyways thanks for the pics!

BTW, the substitute for sea foam is the Berryman B12 Chemtool.

Any top engine clean will do, but since people were talking about seafoam in the other post i would name it after that (and i use seafoam)

Yeah, i'm a tech not a photographer, sorry if they are hard for anyone to see. It appears that the pics are not loading, i will try to fix that when i get home, but the write up is also in the "Seafoaming the mz3 engine) thread.

its used to clean the engine, i just did mine yesterday, at 59400 miles, 1/3 in crankcase, 1/3 in tank, 1/3 in vaccuum line, i didnt get a rediculous amount of smoke, but enough to trace around the block 1-2 times  :lol: well see what kind of results i get as far as mileage increase. BTW awesome write up!
