Hey guys, new to the site and loving it. Really great diy section . I have a 02 tl-s and i followed the diy section on seafoaming the engine thur the vac line with 1/3 of a pint of seafoam. I turned off the car after the seafoam was all sucked up thur the vac line and left it off for about 5 mins.

When i started the car after 5 mins it started up right away ( i was thinking that was a good sign). I then went on a spirited drive for 15 mins with very little smoke coming out of the exhaust.

Here is where im puzzled i thought there was suppose to be like a hugh amount of smoke coming out of the exhaust but i had very miminal smoke for the 1st 2-3 mins and that was it. Is this normal?

Any respond is much appreciated. Thanks

Probably because you didnt use much seafoam. I always use 1 full can.

Ahh thanks for the reply. Did you think its safe to reseafoam again tommorow with a full can even tho i used 1/3 of a pint today?

did u make sure that the car war at operating temp? that might be your problem then. and use more seafoam if its the first time doing it

1. drive around for 15 minutes to get engine WARM
2. suck 1 FULL can of seafoam through vac line
3. turn car off for FIFTEEN minutes
4.

after you wait the 15-30 min after seafoaming and go for a drive...flashback to the spy hunter video game when you look in your rearview mirror

do NOT wait 30 minutes after foaming!!!!!- that will allow too much engine and exhaust cooling off time
You NEED heat in the CAT to generate smoke as oils in seafoam and heat react= smoke, so dont use that as a guide as to how much crud was in the engine

Please read the last few pages of the Seafoam DIY for the latest info-
Make sure you are using the MAIN vac PORT/Nipple on top of TB to Intake
Use of that smaller hose on fender is bogus info and does not feed all 6 cyls
Put it in slowly in small amounts- keep engine from stalling
Should take ~10 minutes to put in full can
Remember to clean the TB plate with carb cleaner or Deep Creep (seafoam in aerosol form)

Thanks for all the respond. Will try a full can of seafoam tommorow morning thur the vac line again but this time im gonna follow the tips listed in this post.

vac PORT-Nipple at the top of the TB to manifold connection is what you need to use

Use a small length of clear hose to watch how much is getting sucked up at a time- small amounts-
or buy seafoam in a spray can- sold as Deep Creep- awesome control over amount, and works to clean throttle cable springs and the TB plate

i always do an oil change a few days after i seafoam

despite the rumor of tons of seafoam getting into the oil during vac and gas method- its not a reality-based on engine building techniques

As long as you are going to change the oil- throw some seafoam in the crankcase oil and idle in driveway or drive 15-30 minutes
As an experiment I put a new filter on, added 1 can foam and drove 150 miles- then new oil and filter
Amazing amounts of crud in the oil filter
If seafoam was getting in there in quantity when I do the intake method- the oil filter would have a lot less crud than came out

In normal internal combustion engines like ours- there is a small amount of open room between the ends of the piston ring- its needed for temp expansion and contraction within differing metals
So as the expanding burning gasses push the piston downstroke, it forces a tiny amount of unburnt fuel, oil residue (thanks to PCV) and other combustion byproducts thru the few mm space,
Note it has to go thru a few sealing rings of different types-compression-oil control--there are usually 5 or so rings stacked on each piston
The openings are not lined up in a clean path-so as to reduce blowby

End result is there is always some of that normal operating crud getting into the oil, a speck of seafoam wont harm anything
