Seafoam!

For those of you who don't know what Seafoam is, it's just a motor cleaner like MCCC. It comes in a can at any auto-parts store, and you suck it in through a vacuum line (BOV-to-intake mani) and it cleans just about everything! That includes the valve tops, combustion chamber, ect, mainly clearing any carbon build-up that has accumulated over the years. It's supposed to help with idle and overall performance of your vehicle.

I JUST finished doing the whole seafoam this afternoon. Since I was already doing an oil change, I decided to run the Seafoam through because you're supposed to change the oil right after you use it. I've read about how much smoke it shoots out through the exhaust (from the carbon burning) and I must say, that is a LOT of smoke! My neighbor (who is a car nut, drives a C6 vette too) came over while I was doing it and said, "uhh, what'd you do this time?" haha. After I explained it to him, he realized it was just like another cleaner like MCCC.

As far as the difference in performance after using it (my car has 130k on the odo, keep in mind), I have noticed a slight increase in part-throttle response as well as a MUCH smoother idle. I've always thought I had a good idle until I did this and realized what it should idle like .

Seafoam gets an A++ in my book!

And for those of you who want to know more about it, there is a HUGE thread about it on dsmtuners.com, just search for Seafoam and the thread title is "Seafoam Works!".

Just thought I'd let you all know about it in case you've never heard of it. :)



P.S. I am starting the 14b install tomorrow morning! :iceslolan

thanks, i'd never heard of it, good info.

Did you change out your spark plugs when you did it?

Awesome, the car should be running well! I hope the 14b install goes smoothly for you tomorrow...

Keep us posted and get 'er done so you can take the new ride for a spin ;)

I swear by that stuff. It's great to run a can in your crankcase about 500 miles before your oil change. Fixed my lifter tick, and you should see the oil filter elements of some of the cars I have done that to.

Yea good luck on the 14b install tomorrow....hope everything goes well and you dont get too agitated doing it.

Are you sure this seafoam isnt detrimental to the car since it is going inside components? Also, can you elaborate a little more on exactly how it works and how you use it?

Did you change out your spark plugs when you did it?


Yes, I picked up a new set of NGK's while I was out getting all the supplies for this weekend's install. I had $40 with me, and the total before the plugs were added was like $32.xx. After the plugs were added it was $39.64, talk about luck :lol:

And yes, I will be giving a nice in-depth review of the install, the porting, and the difference in power compared to the t25. :)



EDIT>> I just saw metalhead's post, so here goes... Stuff like Seafoam has been around for a long time. Some people use straight water (which takes a bit longer), some use MCCC (Mopar Combustion Chamber Cleaner, I think), and some use other shit I can't really remember. Over time, carbon deposits will build up on the walls of the combustion chamber, and possibly other places too. This can cause "hot spots" that can increase the chance of detonation (knock). Seafoam's job is to clean all of this out to give you a more "healthy" and smoother running vehicle.

It's a very simple process, and don't even worry about hydrolock because it takes a LOT more than what you are putting in to hydrolock a motor! There are many different methods as to how to add it: add some to the gas tank via gas cap, through a vacuum line somewhere along the intake path, or straight into the crankcase via oil cap. I used the most common way, using the BOV vacuum line that runs to the intake manifold. I unplugged the vacuum line on the side that connect to the BOV, stuck it down into the can of Seafoam, started the car up and had my brother sit in the car and keep the revs up (this is because the car will try SO hard to die on you!). As soon as the car started up, the smoke came pouring out :biggrin: . Continue this until you've used the entire can and then turn the car off. Wait about 10-15 mintues (at least) and then start her back up. After this you need to take it for a very SPIRITED drive! I romped on mine right after, and you'll know when you've done it enough because the smoke will pretty much cease to roll out of the muffler. That's really all there is to it! It's best to do this right before you are due for an oil change, because you MUST change the oil and spark plugs after you use this stuff. The reason is because it can leak down past the rings and mix with the oil (not too great of a lubricant, that Seafoam ;) ).

If there's anything else you need to know about it, just let me know. OR you can go here and read through all 7 or so pages about it... http://www.dsmtuners.com/forums/showthread.php?t=123649&highlight=seafoam

Yeah, I dont think these things are meant to be MIXED with oil. They're pretty hardcore cleaners. I've done something similar in the past, just poured some Marvels Mystery Oil in the sparkplug holes while the motor was still hot, and let it sit over night. Tons of black smoke out the ehxuast on the way to work ;) Didnt bother changing the oil after, since MMO is an oil. Thats something that I add to my oil a few hundred miles before an oil change. After using it on the old 73 Nova, and then pulling the valve cover and being absolutely amazed, I've been using it ever since ;) I also add it to my gas every now and again. Use it in the diesel too. But this is something different from the MCCC and Seafoam. Those a re bigtime cleaners, and there is a whole long procedure that goes with them. The MMO is more of a maintenenace type thing you can do monthly or similar after you've douched it good with the other stuff.

And good luck with the 14b install ;)

Seafoam should only be used on higher mileage cars, FYI.

I have heard of plenty of people mixing seafoam with their oil. I believe it says on the can that you can. I personally have never done it. I just use seafoam in the gas tank.

I've used seafoam also and never really had any GREAT improvements... done the vac line, gas additive(LUCAS gas add is better), and even cleans tools up pretty good..... but I have not used it in the oil for my turbo..... There are a few oil "thinner" products you add to oil to remove build-up/gunk and some of them say not to use with turbo's.
Anyone hear anything like this? Will this application be detrimental to the health of the turbo oil seals?
I did the vac line trick and my lifter tick is pretty much gone at start-up.... but for some reason I am losing oil...not on ground....SO I am curious to if it might have done something to the valve seals or the like!?!?
I still give SEAFOAM a 2thumbs up.......

gahhhhh, ok i just bought all the stuff, so now i have no damn idea where my vacuum hose is, or if i even have one :confused: help??

There are a dozen of them, on every motor ;) If this is any indication of your technical knowledge, or lack thereof (which is perfectly fine!), I would highly suggest you follow the link posted above that should have a lot more detailed info on how exactly to do this. Spend the time to learn now, or spend the money fo fix mistakes later :) (Look, another sig quote... I'm full of this shit :D)

i'm only 17 so i'm no genius, yet. i was just kind of paranoid because i was looking at that dsmtuners.com thread and they all have turbo dsm's. so none of those pictures and whatever they have would work for me.

ok, i found some vacuum hoses, and well, they ain't vacuuming up the seafoam. and yea i'm pretty sure they are the right hoses because i have one of those repair manual books and they have a diagram of my engine and so on. so will ptting the seafoam in my crankcase work just as well?

Did you rev your car up to 2500rpm? I think thats what you have to do.

let the car idle. vacaum is higher with the throttle closed. at work we usually hook to the brake booster hose but then you need to have a adapter to go from the big brake hose to a small hose to put in the can.

i took off my boost gauge tap at the tb and with a long vacume line i put it in the can and did it thats way.ill tell you one thing you will find exhaust leaks quick and it did help in a few ways.

Did you rev your car up to 2500rpm? I think thats what you have to do.

i only had it up to about 2000, i tried 2 different vacuum hoses and neither one were a go, so i was going to try the brake booster line but i couldn't the bitch come out enough so it can go into the wider mouth bottle i put the seafoam in. i'm guessing pouring the stuff right down the tube would be a major no-no too right? maybe if i did it little by litte it'b be alright, but i'm not taking any chances.

and everyone keeps saying you have to rev it to get it through cause the engine will try to die, which it sounded like it might of but i never really gave it the chance to.

if it stalls that means you're feeding it in too fast. let it idle and let it suck it up slowly.

ok, i'll try it, what about the whole brake booster line then? i cant get it to come out far enough, so should i slowly poor it down the tube? or get that adapter that you said you used?

Could you possibly use the PCV valve hose going into the intake manifold?

think i tried that one too. doesn't matter now tho, i just dumped it in my crankcase. so i'll let that run through and change the oil within the next 100 miles.

Dude... I don't think you are supposed to drive with it in your oil!!! You better check.... It basically thins out your oil which in turn disolves some of the oil sludge build up.....throughout the engine....

If you did try it through the PCV valve it would have been sucked right into the intake manifold!!! Unless you have a turbo and you have boost applied the intake manifold ALWAYS has a vacuum in it while running!!!!
As for it in your oil.... I put a can in right before an oil change with engine at normal operating temperature and let it run/idle for about 10 minutes, let it sit/off for about 5 mins and then drained it... well this is on old cars I had.... I still don't know if it is safe for the turbo seals and such but yeah...........

You CAN put it in your oil, but on a 2 liter engine I run in a half can about 500 miles away from an oil change. I don't like the idea of it being in there for a long time.
