ok so i was dropping in a k&n filter today when i noticed something that looks like a resonator right?


i don't want to run the engine without this since there is an open hole now at the bottom which will suck in unfiltered air.


does removing this make any engine sound difference? and nothing i can do about that resonator hole?

as for seafoam, i was wondering if it is safe to get 1/3 through PCV valve, 1/3 through crankcase and 1/3 though gas tank. also is the PCV way really necessary? can't i just do 2/3 gas tank 1/3 crankcase? and do i need an oil change after?

as for map sensor, is it the shiny metal pin near the throttle body? cant i clean it with q-tip and alcohol?

thanks in advance.

Yea that funky looking thing is an extra resonator for the TL-P cars. You can safely remove it, but I would cover it up somehow. Plastic bag oughta do it.

pickler

can i just wrap it with some clear tape, won't melt? and does it change sound or is there another resonator or something.

pickler

actually i decided not to remove resonator because it diminished throttle response after a test. someone on bimmerfest told me that resonators can help keep a reserved amount of air to improve throttle response as well as mute intake sounds.

randomthought

That is one resonator. Other one is behind the driver side foglight. Can remove that with no problems, unless you don't want to hear the engine at WOT.

Dunno about the throttle response, but I think others have removed it and capped it with pvc. Just be done with the resonators and get a CAI.

Yea i removed the resonator and it doesnt change throttle response or anything, at least for me it didnt. Also, like randomthought said i love that i can hear the engine at WOT as opposed to keeping it muted with the resonator there. Its all up to you though.

This is one of many.

There should have been NO diminished throttle response. And the guy that told you that is wrong. They are for sound only. If that were the case EVERY one with a CAI would be complaining of bad throttle response.

no on seafoam thru pcv!! unless you remove it and clean seperate,
not while engine is running!!! no on brake booster for seafoam too!!

yes on seafoam in gas: 1 can to just under half tank- do that twice and its better than vac port and gas
that 1/3 can each place is 50 year old marketing!

The oil/crankcase is done right before your oil change

TB air plate gets cleaned with carb cleaner/rag,,
why are you messing with a map sensor?

can seafoam master vac port at tb- or just do 2 tanks of gas- thats better and safer

considering the resonator is AFTER the filtered box.. i dont think your car is sucking in any "unfiltered air"

Karanx7

There's 2 resonators on the TL-P. One is between the TB and the filter box, and one is after. If he were to remove that resonator without capping it, he would be sucking in unfiltered air for sure.

no idea there was one down there...

just cap it with pvc..

KatabaticSaint

I did this a while ago and hated it. I capped it with a rubber insert fit beautifully and I thought i was in for a treat but it hummed alot at idle soooo annoying and it felt kinda sluggish. bUt I might just be paranoid however the sound at about 6k was niceee

pickler

ok thanks everyone for resonator info I'll need to remove the bumper so I'll do that later.

why are you saying not thru PCV valve? everyone is doing it, including 2 DIY here. I already did the Seafoam and your scaring me lol. 170ml thru pcv, 50ml crankcase and rest in the tank.

You're supposed to use the vac line but if it seems ok, whatever, just use vac line next time.

01tl4tl

pcv is a small shaker device on rear line above valve cover
you dont put seafoam thru that- never seen a diy saying too
you should clean it by itself- based on clogging on a few ziners cars

maybe we are calling parts different names

we do use the MASTER vac port at the TB- a metal tube/line comes out from the manifold is where seafoam goes in
thats a great place= that feeds all 6 cyls
Or spray thru the TB mouth- thats fine and gets the air plate clean

either one is a good way to introduce it, for direct immediate cleaning of intake valves and pistons

or do the gas tank method 2 times and you are good to go

Noobs to seafoam should repeat vac or gas after a month or so - then good for a year

that vid shows someone who is ignoring the startup and drive instructions on here,,
at least the newest one titled `seafoam diy for for 03` with the good info

there is an old diy using a small vac line on fenderwell that was found not to feed all cyls, after it had been the diy for years!

01tl4tl

once again, cleaning dose in gas is 2 ounces seafoam per 1 gal gas
thats about 1 can to just under a half tank of gas

in oil- 1/2 can in the oil- drive 30 minutes/miles and change with oil warm
you can drive more if you want

vac port- 1/2 - 3/4 can is about all it will take and still be running~
seafoam tech support says more than half can in intake is not doing any extra cleaning

pickler

this is the DIY
https://acurazine.com/forums/2g-tl-1999-2003-98/diy-seafoam-03-tl-s-638176/

I followed it word by word. used a tube I made to slowly suck Seafoam through the metal valve/nipple. I went on spirited drive after for 15min hitting vtec and keeping overdrive off D3.

I also have regane PEA based FI cleaner haven't poured in yet until low on gas.

KatabaticSaint

That is the Master Vac Port not the Pcv you're good no worries.

pickler

thanks

01tl4tl

so we are good then?

sip sip is ok- but try Deep Creep/aerosol seafoam for better control and way less effort

remember to clean the TB air plate and lube the throttle return springs

01tl4tl

ck the max allowed dilution ratio on can- ck against makers website,,like seafoam says 1/3 can in gas but fails to mention thats a 5 gal tank~

pickler

oh ya it definitely was a sip sip took me forever to get a cup of it into the engine. i wasn't sure how deep creep works thats why i just went with good old seafoam.

and i heard lot of good things about regane fuel injector cleaner, which i will put in the gas tank next week when gas tank will be empty. so im not too worried about the seafoam in the tank. 2-3 cans of seafoam in the gas tank to make any difference or just 1 bottle of regane.

01tl4tl

I dont know regane strength but can state that 1 can seafoam in 8 gal-just under half tank does an awesome job= you feel results quickly

Seafoam support guy says twice with the 1 can in half tank = 2 oz per gal cleaning dose,, beats manifold vac port method!
gas gets all the fuel system lines injectors etc- many tiny places fuel needs to go thru that get clogged... from the crud they put in fuel!
of course it gets the intake valves and piston tops- as thats its destination~

01tl4tl

sip sip should take about 10 minutes for most of the can,,1/2 to 3/4 can is plenty
Only differance in deep creep is its 100% seafoam -but a 2 ounces less in can

which appears to be result of cans running out of propellant before the end--when dispensed slowly like we do,,hit it hard and fast with seafoams 2000 rpm method and max blasting,,lots of smoke- lots of instant cleaning, lots of fun on the afterdrive~ and the can last the entire time

ck www.seafoamsales.com multiple tech sections for many ways to use seafoam

at idle isnt the best for us,,a combo of slow and fast rpm and product amounts is

fsttyms1

See my link above. If you remove the 2nd one you HAVE to plug it. Many have done it, some used hockey pucks to do so. There will be a HUM with it removed. Some like it some dont but you WILL get a lot throatier intake sound with it removed.

KatabaticSaint

Yeah I bought a 3 inch rubber end cap for three bucks used the metal clamp off old resonator and it fit real well, I liked the sound at wot but the hum was awful I drove for a day wit it off rolled into a parking garage and it was deafening i hated it. It's worth a try to just see how it sounds though.

KatabaticSaint

Btw fsttyms1 do you know how it was originally the 2nd res i think i put it in backwards or does it matter?

pickler

well regane is PEA based and thats the shit for cleaning the injectors, i don't think seafoam contains PEA.

whatever makes you happy man

Hey guys kinda late and all, but I always thought the U shaped tube was to catch any water that might have gotten into the intake and catch it.
b/c when i took mine out a bunch of water came out of it

01tl4tl

stop washing the engine with the pressure washer
or the car went thru some heavy duty puddles?
stock airbox-resonator up to there?
how was the filter?

fsttyms1

It is NOT designed to catch water. If water is in there STOP driving thru deep water or pressure washing the intake/engine. Or check o make sure all connections on intake are tight.

Gabru678

iTrader: (1)

yea I only drove through a puddle that deep once. the engine did get a bit waterlogged
But then I removed the resonator that weekend so that might be why there was water there that time.

Hmm I didn't know washing the engine with a powerwasher could even get in there.
THE MORE YOU KNOW!!

and the filter was fine BTW

01tl4tl

water gets in the worst spots with a pressure washer
Use fine mist spray from low pressure/garden hose and your choice of cleaner,,gunk,whatever

As I understand it, the logic is simply this.

If you do the Seafoam thru the vac port, it's a quick process. If you think of cleaning parts with a spray cleaner it only gets some of the build up off. Now if you soak the parts in a diluted solution it will get more of the build up off. So Seafoam in the tank will work on eliminating the build up more completely as it is "cleaning" the entire fuel system until that tank of gas has run out. This is also why those who don't add it as part of a regular maintenace program will likely need to do it two times.

Hope this helps.

thats pretty close- blaster thru vac port gets instant results,,on what it reaches, no kidding! can tell the differance on after drive

while thru the gas tank gets critical areas never reached by vac port- so you really need both, or gas method twice for the nervous will take care of all of it
over a slower time

all noobs to seafoam are suggested to repeat in 1-2kmiles, to finish off the job,,
there can be a learning curve to application..
and some residual crud from 10 years of driving before you found out about this stuff,,, then its good for a year

Optional: can in tank midyear/at oil change time to `maitenance dose` it

tier 1 gas helps too- has extra cleaners built in

pickler

i have always used good 91 octane gas in my car, shell v-power 0% ethanol. anyway after half a can of seafoam in the vac and half in gas tank i did not feel any difference. there was smoke for about 5 minutes though.

01tl4tl

lucky you no ethanol!! but you have to live in Canada to get it~

seafoam in gas what dilution, 1 oz or 2 oz per gal,,cleaning dose is 1 can to just under half tank

half can in full tank isnt going to cut it
smoke is relative to heat in cat and oil in seafoam
you may need to clean the TB air plate still

did your overall mpg /lpk go up a little?
noobs need to repeat after a month for best results then good for a year- and follow the diy

brnm8brn

so far the only thing i like about living in OKC is the 100% gas no ethanol option here as well
