Sea Foam Insertion Point

Spdrcer34 said:
I am saying that the FRONT cylinders will get fed, just as well as the REAR cylinders. If you introduce the SF into the MIDDLE/REAR of the intake, only the MIDDLE/REAR cylinders get fed. Period.

hehhe. You post as if I were questioning you. I happen to agree with you...I was only confused by your explanation. That happens to me though. :) But a simpler way to say it would be, that from the point of insertion, the mist will travel with the air. It can't go against the grain.

Regarding smoke: In contrast to al, I have never gotten too much smoke with Seafoam. Kind of interesting.

so where is the BEST place to put sea foam in a ohv???? pics will help.. :D


and on i side note has anyone put SF in there crankcase??? that means in the oil filler, right?? And for how long? 1 mile, 10miles, or 3000?

thanks
 






well i searched and found there phone number (not on the can). and they called back this morning. He said that i could leave SF in the oil till the next change up to 3,000. i am not sure if i will let it stay that long. But to get rid of varnish he said it should be gone in less then 100miles.
 






To each his own, but I don't believe in putting anything in the engine oil. If I were you I would change the oil pretty soon. Might as well, it's cheap insurance. Then you could rest easy knowing you had straight oil in there. Why have excess varnish etc floating around in there, or clogging your filter?

The BEST place to put Seafoam...hehe. Big thread about that here. I have an open mind about it. That is the $64000 question, it's the question I am trying to answer...last time I used SF I put it in thru the TB vac port. Prior to that, I had always used the BB line. In the past, my SF treatments lasted about 7,000 miles and then the truck needed another treatment. We'll see how long the new treatment lasts. (it's only been about 1000 miles) I know, it's not very scientific, but it's the best you'll get outside of a bonafide lab doing the testing.
 












This makes for interesting reading, but I am about as confused now as I was when I started reading the 1st post. It would be nice to know for sure where to put in the SeaFoam. I have head one should not put in through the Throttle Body? Yes/No ?
I would like to do the treatment on my daughters 96 XLT w/142,000 miles. I use it on my 200 hp V6 2 stroke outboard all the time, but I mix a can w/ 3/4 glallon of gas, (3 oz of TCW3 oil for lube) run it for about 15 minutes on a water hose for cooling purposes. Let it sit for about 1/2 hour and repeat the process until the small gas tank is empty. You don't want to do this on your cement driveway because it will covered with black carbon. It really does clean out the carbon build up. If it does that on an outboard, it should do the same thing on a 4 stroke auto engine.

well first we need to see a pic of your daughter, she is 18 right? ;)
 






Man these SF threads never die do they :confused: I'll second or third or fourth depending how many of these SF posts you've read...that what ever intake cleaner you chose to use it WILL ONLY travel with the direction of air flow...not against. Therefore if your feeding it through the BB, vac tree, or any other vac port on the backside of the upper intake, then your only reaching carbon deposits from that point on in the direction of flow. Your NOT doing anything for the majority of the upper intake, or throttle body. Now technically your still gonna get improvements...because you are cleaning a few of the upper ports , and the complete lower intake. But to me...this is like washing half the dishes and leaving the other half in the sink! Personally, I'm the **** type...if I'm gonna do it, I'm gonna do it right. I never half a$$ it on anything...especially my truck. On the OHV there is a small port tube on the bottomside of the TB right before it meets the upper intake, you can attach a small piece of hose and feed it directly into your TB... thereby cleaning your whole system. I believe someone also said they used the crankcase hose on the inlet tube...which would work just the same. FYI: Gumout has come out with a new TB/intake cleaner for fuel injected engines. It comes in a pressurized can w/ a feeding tube and cost about $3.00. You just open up your butterfly and spray the whole can through the TB while running the engine. I've switched to this...cause it's much easier than dealing with SF in liquid form, and the spray gets more evenly dispersed throughout the system. Cleaning chemicals are the same...just uses a better method IMO. Hope this helps !
 






ok to throw more confusion.. i have a carb on my toyota .. should i jsut dump it down the carb barrel? the priamry? or should i run it through the brake booster line also? or?
 






i would just dump it down the primary
 






SeaFoam has a spray out called DEEP CREEP, same formula as the bottle except in a spray can. I will have to look for it and try spraying through the throttle body.
 






I'd use the motor treatment over the spray. I use Deep Creep as a penetrant. Spraying in a little at a time seems pointless when you can let the engine suck a nice amount out of the can. As for the question in this thread.. I ran through my BB and barely got any smoke. Ran through the TB line and got A LOT. That tells me which way is better.
 






Huskyfan, how did you run the liquid through the throttle body? Which TBline, the one under the TB?
 






Yeah, the one under the TB.

How do explain the fact that there is a vacuum throughout the system and by incerting the Sea Foam through the brake booster vacuum line it enters the system?
 






I the vacuum line on the bottom of the throttle body a part of the OHV motor? There are NO vacuum lines on my '99 SOHC.
 






I'd think since the brake booster line isn't at the very front of the engine like the TB, it's not going to hit every chamber. Starting at the front of the engine just makes more sense than starting at the middle or end.
 






I go with Husky on this one.Putting the seafoam in thru the BB hose makes no sense as the airflow is front to back as we all realise.
Given the fact that all Cylinders are sucking air equally, What I am going to do is remove my mAC intake, drill and tap it for a brass fitting well after the MAS and a couple inchs before the Throttle plate and use that as the insertion point.
I think all Cyls will get and equal amt. of S.F with the added benifit of also cleaning the plate. JMHO

Airflow at WOT might support your contention, however, at idel there is very little airflow.

Al, with all respect, have you ever pissed into the wind? :eek:
