I drove for 20 miles to let the engine warmup before starting the procedure. To apply deep creep, I opened the vac port and attached my own tube to it and started spraying seafoam slowly from the other end. The process went on for over 10 minutes for 8 oz of the stuff. The white smoke started coming out slowly when I was halfway through the can.

After 15 min waiting period, I did 4000 rpm for 3-4 min ONLY and then multiple throttle pushes up into vtec for another 15 minutes. May be thats the reason for the CEL issue. Anyway, I plan to do this again after 1-2k miles and will make sure that I do the 4k rpm run for over 10 min to make the engine super hot.

Thanks for the all the help.

after letting it sit and going for a drive how long will it smoke before its stops

01tl4tl

usually it smokes bad a few minutes then gets light- with big puffs on throttle romps
Its gone before you head home

To the person who only took 2 minutes to suck the can up- try reading!!!
Even the can has directions!
I cant tell you how many times in this 1 thread its been stated- slow sip sip sip
or use the deep creep spray can- light sprays- wait-spritz spritz--
10- minutes OR MORE, to get in 8-12 to 16 oz of seafoam is a good rate

Its hi detergent oils that need to cling to crud and dissolve it- then it goes for the hot foot hi rpm hi heat hi exhaust flow drive and blows the crud out

MUCH of the original smoke is the oils hitting the cat- which is why you want everything hot- to burn them off with the crud

If you are unhappy and blame the product and not your poor useage of it- take it back to the store for a full refund- no hassles!!
Otherwise get a can for the gas tank- 1 can to 1/2 tank
and 1 can deep creep for slow install of product to engine
Make sure you are removing the plastic engine cover to reach the proper vac port- Anything else is the wrong one!!!!

Noobs using seafoam liquid in vac port --should pour into plastic bottle to observe the suction action of the engine with liquid and slow it down to sip sip sip

CAB NY

cool it should take 10 minutes to put in the whole can also do you put a can in the gas tank 1/4 full at the same time

totaledTL

and the seafoam sagas continue....

01tl4tl

I use :

1 can in 1/2, one HALF tank of gas. So its 2 ounces seafoam per gallon of gas in the tank= half tank is approx 8 gallons.

You can run it harder dose , but better to add more when refueling to give it more time- rather than stronger dose-- to do its job on the injectors and valves

Everyone has seen the Shell 5000 mile test, tv commercials- the crud is real!!!

i seafoam the vac lines today and it already seem like it runs alot smoother. im about to put a can in the gas now. will i notices anything if i put it in the gas? and what about the oil.

01tl4tl

I suggest putting it in the gas before the vac port drive- so its gettng cleaner dosed fuel during the fun run!
You will feel a better running engine over the next week or 2 as it goes thru the gas and blows out more crud- gas mileage should improve

You wont notice much change in running from the oil, but it helps the engine
Make sure you change it right away-

thinhthan

so should i redo the seafoam again and put it in the gas and the vac lines this time? i was thinking about doing it in the oil to since i need a oil change

maxxxboost

Good read
doing to dump 16oz of Seafoam in my car tomorrow. Good timing, it's at 1/2 tank of gas.

01tl4tl

get a can of Deep Creep too- seafoam in a spray can like paint
Makes the vac method easy to do- no hose and stuff required
If not found- get regular sefoam and do it slow sip sip sip method of hose and can

The inside of the intake, valves- piston tops, is loaded with carbon and unburned byproducts that a re bad for airflow-fuel flow and combustion.
Everyone over 30,000 miles will benefit from this- when its done right especially!

maxxxboost

So i was all pumped and ready to get this done. Well, turns out that the only place that i could find this product was at Lordco *Kingsway location for all you members in Vancouver*. (Lordco is like a NAPA)

Problem, they only had Seafoam- Deep Creep ($11.99Cad +/- )
Problem, they ran out and said they'll be getting more tomorrow.

I decided to use a whole can of Honda Carb Cleaner and did my throtle body.

Question, if i do decide to do the Deep Creep for the intake valves. Will it be too much since i did the carb cleaner?

Please give me some insigh Seafoam Gurus!

03aspec

lol... lordco is poo stay away from that place.. hit up napa! i bought 2 cans of regular seafoam and 1 can of deep creep from napa, they had plenty in stock.

01tl4tl

while carb cleaner is fine to use on the TB throttle/air plate inside the TB (make sure to clean that) its instant flammabilty means its not syaing in the intake long enough to do much DEEP cleaning--surface cleaning is one thing, but cars have layers and layers of crud built up on the important parts.

Everyone has seen the tv commercial showing crud on valves after 5000 miles.
Seafoam- being hi-detergent oils- will burn thru (can be used as starting fluid!)
but it sticks to stuff and dissolves the crud- turning it to goo during the 15 minute waiting/percolate time--- which then gets blown out the exhaust with the
4000 rpm 2nd gear 15 minute run - 3rd gear if speed laws allow ~
That will make lots of heat and melt and blow out crud.

The extra runs from low rpm with full throttle to vtec are making sure that while its hot- you run lots of treated gas thru the injectors- and intake valves and piston tops
to ensure a good job.

If you did it funky the first time- its ok to repeat now.
Normally- 1st timers should repeat in a month or about 2000 miles- to get the remainder out and then set for a year
Ok to use as fuel cleaner every 5000 miles if you want, before trips...etc

i just used the deep creep through the throttle body today and i must say that i am impressed!! i can notice the idle is much better. now the car would be perfect if i could afford to get new motor mounts!!

CAB NY

good instructions everything worked fine just feeling the heat during the 10-15 minutes to suck in the sea foam

maxxxboost

LOL

I'm not familiar with Napa.
Where is Napa located? I need to pick up some regular Seafoam.

Hum... ok.... time to deep ceep the heck out of my car next weekend.

01tl4tl

I forgot to mention-
when using deep creep/seafoam for intake vac port method-and its 10-15 minutes install time:
WHEN the engine cooling fan comes on- step back from the car-
so as to avoid the blast of hot air!!
Its fine to let the car idle for a minute without adding more seafoam- its allowing it to process better actually!

03aspec

lol.. depends on what part of van your in..

CAB NY

if you keep your oil changed on time is there a need to add to the oil

fsttyms1

Define on time????

And it never hurts. Just wait to add it till its time to change the oil.

CAB NY

3-5k miles

i need to change mine this week and what is the correct way to add it how soon before the change (how many miles) how long to leave it in before the change

nsx04

so i did seafoam today. Bought myself a can of that spray stuff (deep creep) and I didn't get any smoke out of the tail pipe at all.

I'll describe what i did here:

Drove car to Napa (about a 5 min drive, i made sure i warmed up the engien by runnign some WOT starts and teh temp gauge was well in its working range)
Bought the Can of deep creep
Drove the car some more around the block to make sure it's really warm.
Shut engine off and took apart the plastic cover and took out the vac line as described by the new method.
Then i started the engine, and began feeding the deep creep stuff into the vac line, doing the squirt squirt wait method (went on for around 13 minutes and i think i have half of the can in, not too sure as it's hard to judge how much was left in the aerosol can. And i assure there were spray by holding the can upside down and squirt)
Then i stopped doing it and shut down engien and connected back the vac hose, closed hood and waited for 15 min.
After 15 min i started her up and there wasn't much hesitation with the start, except the car bogged and felt rough while its idling, but it never died out. waited maybe 10 secs and the car felt smooth and stabilized and i drove out, holding 2nd gear driving for a min at 2000rpm. I proceeded to the highway where i did pulls from 3000 rpm to 5600 rpm, and occasionally dipping into 3rd gear. (and still no smoke at this point) i did that for a good 15 min and there were never smokes out the tail (i attest to it because i literally see no smoke in the back window and side mirrors while i was driving)

But the car seems to run very smooth now. a little smoother than before when its in vtec and idle. Reason why i did seafoam was because my parents forgot to change the oil for about 10000km and when i came back to check up on car, the dipstick was pitch black. So i did the oil change, and now the oil is back to normal colour, but the car doesn't feel fast (changing oil did nothing to improve) so i'm like..well maybe i'm just paranoid. but then i was chased by a rolla XRS, we did a pull from 50mph to 80, and to my surprise i did not catch up! in fact we were actually travelling at the same pace! I was like WTF! I walk G35 sedans, and my friend's 4g eclipse GT would walk me from roll, why would i be on par with this XRS, and these cars struggles to run RSX-S? And i assure you i had VSA off, and i had the lever in 2nd gear and i did not mess up anything. So i guess i was right about the car being slow. My car has XS header and a CAI.

I had checked the intake actuator and it does work.

Anyway, i'm just surprised that i didn't get any smokes after seafoam....I'm sure i had followed the steps right because i was up studying this the night before....Anyone have insight on this? And o....the car feels smoother, but i still don't think it's got power back yet......this really stinks....I suspect I had not put in enough seafoam? i dunno....

Try following the warm up directions properly,
be ready to do seafoam as soon as you stop- not fiddling with the engine cover
Then use the entire can!!!!- shake the can to tell how much is left- its very simple~
No reason to hold upside down- the can sprays the same in every direction!!

first timers really need the entire can in to get effective cleaning
Smoke is relative to cat temp- no smoke? not effective temps being used!
and you dont always see anything in the mirrors unless you get a big blast at first
again- using the entire can will produce that result and then some~

When the oil is black-
you need to put a new filter on- add seafoam liquid to engine oil and drive up to 100 miles to clean the glaze and sludge off everything.
Then change the oil and filter when engine warm.

Maybe you are ready for new spark plugs- driving hard like you do puts wear on parts
New plugs at 70k miles for normal drivers- sooner for racers

did you clean the TB plate as directed too?

I just did the seafoam experiment on my '02 TL....just the vac line & gas tank because I got an oil change just last week.

The vacuum line I used is the one that was previously posted below. I took off the old tube, put on my own and dipped the other end in the seafoam can. First time I did it, the engine stalled. Then I got the hang of giving it some air so that it doesn't stall. I messed up because I put 3/4 the bottle in there when I only intended to put in half. After putting it in the vacuum line, I cut the car off and it was knocking like crazy with a little smoke til it finally cut off.

Then I put the rest in the gas tank and waited about 15 minutes. I started right up but had to keep giving it some air so that it wouldn't stall. Then it sounded smoother & I didn't need to open throttle anymore.

Then the smoke came. It was wonderful. My gas tank light was already on so I did my "free-spirited" drive on the highway....averaging about 3500 rpms in third/fourth gear. Then did a couple of flooring from 30mph ->70mph sweeps. I was still goin easy because I just got my "new" transmission two weeks ago and have only put on about 500 miles since.

End result: I can't tell when the engine is on anymore; definite improvement in noise reduction & smoother idling. I never really drove the car crazy prior to seafoaming so I really was "discovering" how great the car is in terms of performance for the first time....it was awesome; I like this car!

PS: CEL did come on. It went off after about 15 miles or so.

I just picked up my first can of Seafoam. What line should I use?

newperson

iTrader: (2)

You should know this...you started the thread.

01tl4tl

careful using the liquid seafoam in the vac port with the hose and dip and sip method~
Its easy to get too much in at once!!- you want a controlled 10+ minutes of time the stuff is going in
Using seafoam in its aerosol can sold as Deep Creep makes the job really easy

Following the directions on warm up drive AND especially the after drive, that I have posted-- will result in max effectiveness for your dollar, or 7 bucks as it were~

Thanks, newperson. I was really confused with the 10 pages of stuff to go through.

That's still 70 posts!

The problem is the DIYs on here are like 50 pages long because they get cluttered with comments. A DIY write-up is something where within the first couple of posts, a person reading it for the first time has a good picture of what to do. And no offense to you 01tl4tl 'cause I value all the great info & contributions you make to this forum, but sometimes I have to reread some of your posts to fully understand.

01tl4tl

the mods asked me to condense all the knowledge down to correct pics and instructions and make a new DIY with directions only.

If they were going to pay me, I would get right on that....until then -

01tl4tl

as long as you understand the vac port location, and put the deep creep in there- realllly slow
and liquid seafoam in the gas tank...you are good to go
No matter how much someone strays from the instructons-- they still get results.

kragen has liquid foam on sale this week sept 28.

I just got my 99TL and wanted to do a Seafoam soon. From reading, this is what I should do:

1) Pour a WHOLE CAN (16 OZ) of Seafoam into a 1/4 Gas tank of the Car
2) Take off the engine cover
3) Warm up the car by taking a 10-15 Min. Drive
4) Disconnect the intake vacuum hose and install 5/16"tubing in its place
5) Start the car
6) Now put the 5/16'' Tubing into Seafoam that was emptied out into a plasitc bottle to see the contents.
7) 1 Whole can goes into the Vacuum Hose spot
8) Drive it for about 10-15 mins again

IS this procedure correct? I also had some other questions:

1) I've read people putting the seafoam in the gas tank first then the Vacuum Hose and vice versa, does it matter?
2) To disconnect the vacuum tube, do you simply just pull it out? and to reconnect it, just push it back in?
3) I should barely hover the 5/16" tubing above the seafoam to let it take the seafoam slowly correct?
4) Once the seafoam is done, do I have to let the car idle for a bit, or do I just take it for a spin immediately?
5) I heard that the CEL will probably come on, How long will it take for it to go away or do I have to reset it myself?

Any other tips to make this process go smoothly. I will attempt this soon and just wanted to get my noob questions out of the way.

Thanks

also, what is this deep crank, and is it necessary? How would I work it into the procedure described above?

Deep Creep is Seafoam in an aerosol spray can. It just makes it easier to apply and you can spray down the TB plate and throttle cables to relieve a sticky throttle.

Deep crank-
