Seafoam treatment

This has probably been done a bunch of times before, but I decided to do the seafoam treatment last night. Man did it smoke like crazy, I let it idle for a while til most of the smoke was gone, then backed it out to get the rest out, I didn't even really get it on it, but I left a gigantic cloud of smoke down street. I imagine the neighborhood hated me at that point...

Anyway I can't tell if it made anything better or not, at first idle felt smooth, it at least sounds smoother. It seems like I have a little bit more go, and at full throttle it seemed like it ran to 6000 RPM way faster than it ever has, it actually surprised me. I may run some more through my intake as I've heard that as once you clean it out the seafoam will smoke less and less?

Also one thing I was wondering for my next oil change which would you guys recommend for my hydraulic lifters. Adding Seafoam to my oil and running it around a bit or ATF?

I dont know about hydro lifters but i ran it in my N47 head and it worked great.
and it helped me figure out what was really wrong with my car.

P.S. i pissed off my neighbors with it too! haha

Did you let the engine set for a few minutes with the seafoam in the system before you started it up again? Lots of people dont know thats the right way to do it.

Every time you add seafoam to your engine, it will smoke regardless of how many treatments you do. It will smoke less the more treatments you do, but it will always smoke a little because the engine is burning the seafoam.

It will make it run smoother when you put it in the intake by removing some of the oils from the intake, and burning carbon deposits off the pistons. If your lifters aren't making any noise currently I wouldn't bother putting any oil attitives in the engine. But I guess a little seafoam couldn't hurt.

Yeah, I feed it through a vacuum hose off the intake and it'll pretty much want to stall instantly. I'll hold the throttle open more to get a bunch in there. I let the car stall and then I'll let it sit for a while. I'll usually do it before I go out to eat or something, so the car sits until I get back. Yeah it was a huge thick cloud, you could barely see down the street, and then from the cloud a bike rider emerged. I felt bad for the guy.

seafoam smokes ALOT when burnt ALWAYS if it gets less smokey tis because theres less carbon deposits on your valves and maybe even piston tops. thats it. but it wont be all that noticeable since that stuff burns and smokes out black.

Hmm, I ran the seafoam treatment once more through my car. Smoked alot still, but it was way less than before. Anyway full throttle getting on the freeway at stock boost felt like the tires were ready to break traction. It was pretty wild.

Now I don't know if I'm nuts or not, but it seemed like going 70mph my Tach was reading a hair over 3500(3-speed auto) where before I swear my RPMs were higher.

Seafoam every 3 thousand miles or so seems sufficent for me. I did it after i first bought the car and the performace increase was rediculous. In the test drive it felt like a corolla then after a fresh tank of gas ( the gas was a year old in the car) a new fuel filter, and some seafoam for the injectors it started feeling like a Z. Love the stuff.

Any reason not to use Seafoam? Seriously, could there be any negative effects?

I should be there the end of Nov. The project I'm working on ships around Oct so we should be installing it in Nov.

Seriously though, I need to pick some up for this weekend. After that at every oil change? Keeps it all working smooth? My does need a wake up, it's been sluggish and doesn't start to really pull until 3k on the tach.

Sorry about the old thread. But, I have run Seafoam in numerous vehicles. The vacuum port in the intake for the triple weber carbs seems to feed only from one cylinder. Is there an easy way to evenly distribute the sea foam in all cylinders?

Did you guys miss me? hahaha

Yeah, standard triple weber setup, 40 DCOE's. With filter units that cover both throttle bodies per carb.

I had a mishap today. Starting a new thread. haha. But, I really want to run seafoam now. (read other thread)

You are supposed to kill the engine with it. Let it sit, and then run it. I think I will try and do this three times for each set of carbs. Not going to be easy. But, it should be fun. I was thinking of some tube gravity feed system... Fill 6 tubes with sea foam, aim them down the throttle bodies, and then release the fluid. Kinda like holding your thumb over a straw filled with soda. Not that any man here uses a straw to drink with. I am sure you are all to manly to be sucking through a straw like a little girl scout. haha
