i just sucked in a can 1/3 of a can at a time. I happened to look behind my garage as i was walking back to the car and noticed my neighbor looking particularly pissed off about mowing his lawn in a giant white cloud....looked like Cheech and Chong were living in my garage.

You should offer to Seafoam his lawnmower.

I'm going to seafoam my 190k m20 tomorrow and record while driving through the rich white town next a few miles away. I'll just have it suck up the seafoam over there so I can get the full effect Video to come.

Great thread. Looks like I'm going to go buy a can on my lunch and try this stuff out!

Ran one can in oil and fuel. Second can will go through the intake later in the week at night lol

I have a question for all the Seafoam evangelists. Do you worry about dislodging gunk and clogging your oil passages, getting a piece of junk stuck under an exhaust valve, ruining the cat, drying out seals, etc?

This is what keeps me away from Seafoam and other similar products. An engine builder I trust calls these sorts of engine treatments "rod-knock in a can."

Just wondering what the risks are.

if it is already junked up in there....can it hurt it any more? sure the seafoam may dislodge some of the crap in there but i dont think it will block oil passages...that would be pretty extreme.. many of us have used seafoam i personally have put a whole can in my car about two weeks ago... my car still runs...infact much better like its been cleared up.


a few of us have mentioned changing your oil after using the seafoam...because you dont want all that disloadged crap floating around your oilpan for very long. that what i did and i have had no problems. before my next oil change i am going to buy another can and do it again. has your friend use the product before? has he seen this happen with similar products? lets us know...more info is always nice. as far as i know seafoam doesnt have any lead in it...how would it ruin your cat? essentially you are burning built up carbon deposits....which already the cat is constantly hit by...its not like a little more concentration is going to hurt it...unless it is constantly getting it

Sure it can. There's a big difference between a glob of sludge stuck to the bottom of an oil pan and a glob of sludge circulating through the oil passages. Similarly, there's a big difference between a chunk of carbon stuck to the face of a piston and a chunk of carbon stuck in an exhaust valve that keeps it from closing properly.

sure the seafoam may dislodge some of the crap in there but i dont think it will block oil passages...that would be pretty extreme..

Well, that's the whole question, isn't it? The engine builder I spoke to about this seems to feel that dislodging the crap can do more harm than good.

has he seen this happen with similar products? lets us know...more info is always nice.

We weren't talking specifically about Seafoam. We were talking about the stuff you add to the crank-case, like Marvel Mystery Oil, Auto-Rx, Amsoil Engine Flush, etc. From what you guys are saying, it sounds like Seafoam doesn't go in the crank-case anyway. So, I'm not sure if the risks are the same or not.

as far as i know seafoam doesnt have any lead in it...how would it ruin your cat?

I think the idea is that you'll just blast a bunch of unburned carbon though the exhaust system, which may mechanically clog the cat.

if you have sludge in your oil pan, then to remove that you need to change your oil more often... dont want to sound like a noob but im pretty sure there is a difference between oil sludge and carbon build up...oil passages are pretty small sludge is thick..i could see it maybe blocking it up but not neccesarily making it through the passages.. i put my seafoam through the vacuum hose from the fuel pressure regulatore back to the intake. that way it hits the valves and tops of pistons...and yes there is possibilty you have a lot of build up on top of your pistons and a pieces gets lodged in the exhaust valve as it closes...but over time...im sure the piece will a) wear away or b) eventually create its on seal in between the valve seat and the valve. i dont have much experience building engines but just my two cents... as far as i know. correct me if im wrong. like i said ive done it, my car runs better, so do many other members cars, change your oil after you do the shit and you should be ok. my car is an 85...if there is any buildup that could get clooged i think i would have a blown engine by now...my engine is mad old and im sure has a lot of build up...i can see it when i take my valve cover off its all over the place...but i figure hey i can a) keep the build up there or b) burn it up and see if my engine can take it...so far....i drive it a like 5,000 rpms at 90 mph in 4th gear (3.91lsd) and it seems to want to run there all day...

ps i drive my car daily

Well I'm convinced!

I purchased my first bottle of Seafoam yesterday at lunch and added it after work. First off, I straight up died of laughter leaving my office parking lot (where I put in my first 1/2 bottle through the vacuum hose of my M42). I work in a very affluent white town, and my car STOPPED TRAFFIC on the onramp to I-5 due to the HUGE cloud of smoke caused by accelerating. Haha! I was afraid I was going to be pulled over! I ended up putting the other half in later last night.

I've noticed a reduction in pings, stutters, and rough idle. My car has 126k on it and was in good running order before this, but my only complaints would have been somewhat rough cold-idle, with small stutters until it warmed up, and rough transistions between gears, especially 1st to 2nd. The idle is now clean and pure, no hesistation at all. My car shifts smoother through the gears and as others have mentioned it is much happier/smoother to pull through the rev range. I thought at first it may be a placebo affect but after putting on about 25 miles since then I can definitely notice a solid difference. Worth the $5.95 I paid for the can! I would have paid $25 for the same affect.

I imagine the more gunk you have the more noticeable of a difference you'll find, but if you find yourself having rough idles/transitions/shifts/decellerations, try some of this and I can almost garauntee a positive result. I will be using a can of this every other oil change now, or about once every 5-6,000 miles.

So how is everyone's cars running? To me it seems there is no downside to giving this stuff a try.
