Sea Foam Cleaning

[mazdaspeed32007]

I've had experiences with Sea Foam on my 190k mile 1994 BMW 325i... it smoked predictably like a banshee... I'd be a lil more hesitant with vehicles less than 100k miles, no amount of carbon could be power robbing you at 50k miles - its a total waste!

Judging by the running shell gas only and all I'd say you were just following your pattern of great ownership - but at some point you just gotta let the kid go to kindergarten. Ya dig?

thou shall not cuttith of thy umbilical cordicus. for thee shall harness ye' seed who doth turn into boy who one day turnith into man, feel thy age one looks, not the age one IS.

i dont think its a total waste. think of all the stress-ors a motor goes through throughout its life if nothing was done. carbon build up, dirty parts not running properly for thousands of miles, slight torsion of parts under unseen strain. mine....perfectly clean, no part going abused or working harder than it has to, smooth rotation, pistons firing at TDC and moving as smooth as cream cheese frosting spreading over a cake by the hand of the worlds best cake froster. im sure you catch what im saying.

and if you understood all o that.....i believe sir your as ****** up as i am.

Drunken skunks.

Sure your internals are "clean" for a while after the treatment... But if you've ever scraped off carbon from piston tops during an overhaul you know that layer of black crud is back within a few thousand miles.

Again I can only speak from experience on a 200,000 mile non FI motor; yes the treatment was good at what it claimed to do. The motor was noticebly smoother and easier starting - ok I'll give you that. But I'd venture to say that a model that's seen regular synthetic oil changes and thats been driven rationally - with far less miles on it - will see less effect from the magical smoking snakeoil.

Some mechanics swear by the miracle in a can thing you should know... so this stuff does have real applications.

Also don't forget that theres still debate on the effects of all that crud released onto your cat. converter.

i have an 11 inch pypes mini cat....if it s**** the bed ill weld in another. lol.

i do run only synthetic oil, drive highway miles, and change fluids very regularly and am very high maintenance.
and although i defend the fact that i am not a skunk...ill admit to smelling like one due to the spicy jalapeno onion pizza i just ate.

so i decided to run sea foam through the egr hose into the intake mani. it was a vac hose because it was sucking more air than madonna's front teeth. i put in about half the bottle while the engine was running slowly until i shut her down. i let it sit for 5 minutes like the bottle says and when i started it up.....nothing. no smoke. just a little smell of sea foam through the tail pipe. i went for a 5 minute drive and let it run its course pretty good and even at WOT no smoke. not even a puff. wierd? i know it was going into the cylinder because it would idle high when it pulled the sea foam then it would bog a little until the hose was emptied...then i would put a little more and you know the rest of the story. even when i got back from the run i let it idle for 5 minutes. idk....anything odd about this? or was my motor just clean? i would figure smoke just from the sea foam itself at least. the car just hit below 50,000 and i was doing an oil conversion/change, tranny fluid change...and the reg 50,000 maintenence s*** but i found this one odd maybe someone has an answer. i added a little into my gas tank for s**** and giggles. they say you can add to the crankcase but ill wait for that one until i need another oil change if i decide to do it at all. anyway....

HAHAHAHAHA you used the coolant line comming out of the turbo , thats the only rubber line attached to the egr valve, the metal tub goes to the intake and it get its exhaust gasses through the side of the head , you seafoamed your cooling system that why there wasnt smoke, none of it went into your engine!??? Thats Awesome if you did what i think you did.... Man...

I did this and am pretty sure it jacked up my rear o2 sensor or jacked up my cat. I am now getting a CEL p0138 "rear o2 sensor high voltage." This happened about a week after I did the Seafoam and changed the plugs. I changed out the rear o2 sensor for a new one and all the wiring to the sensor looks good so it's got to be the cat on the downpipe.
Has this happened to anyone else?

Possible, but not likely. I did mine two months ago and no codes.
