Quick question about SeaFoam and vacuum ports
 

I am planning on doing the seafoam treatment and was wondering what vacuum ports would supply both rotors equally. It looks like the brake booster line would supply the rear rotor more than the front, but I don't know. Would it be better to pour it down the primaries equally? I looked at a bunch of threads and didn't see anything pertaining to this.

My plan is to get some vacuum line and a T fitting, hooking two lines to vacuum ports and then the one line going to the seafoam bottle so the it can be sucked into the engine and go to both rotors at the same rate. Unless of course the brake booster line would supply both rotors equally, then that would make things a lot easier! :nod:

Thank you in advance.

Brake booster, no, primaries, yes. Other than mixed with fuel, primary ports are THE best option.

Seafoam eats up oil control rings and seals. Turns em' into rubba'.

B.S.

Seafoam softens and helps remove carbon, not rubber. If an engine starts blowing oil after a treatment, the oil rings were shot to begin with and the carbon buildup was doing the sealing.

That's what I was thinking. If that is the case then I know where a running 13b is that I am going to rebuild and swap in. I want to do a large street port on it. That would give me an excuse to get it done sooner!

Hey, I'm not going to argue. Lol.

Seafoam is great stuff, and rotaries especially love it. However, do yourself a favor and just dump it into your gas tank. I've been using the stuff for several years now, and have tried every method of introduction, and the gas tank provides the best results with the lowest possibility of creating issues for you.

Decided not to seafoam the RX-7. I will pour a bottle in the tank this weekend when I will have a chance to really get out and drive it like I stole it. Plus it still has a 1/2 tank of fuel. I need to burn some of that off before I put the seafoam in there. Thanks for all the pointers and help on this subject.

On a side note, I did seafoam my 95 buckfifty tonight. Hell of a smoke show and damn did it make one helluva difference in every aspect of the way it runs/drives! The truck has spent most of its life idling or putting around town by the previous owner, when I bought it it would only rev to around 4300rpm before what sounded like floating the valves. And not much power. Now it pulls strong to 5500rpm! I kinda figured it was pretty carboned up. Truck is a 302 5-speed, reg cab and short bed with only 113k on the clock.

As soon as you put the Seafoam into the tank and start driving, you will feel the difference. And it will continue to improve as you drive it. Let us know how it works out for you. :)

Will do. Looking forward to it. I have a half tank of fuel. Two cans should do it, right?

Run the tank down to 1/4 and use 1 can. No need to go over board.

The problem is that I only drive the car maybe one day a week. It would take a couple of weeks to get it down that far. The seafoam bottle says approx. one ounce per gallon is average. So one bottle to 8 gallons of gas would be 2 ounces per gallon. That should be enough to start the cleaning process. I will probably run that down to a 1/16th and then fill it up to 1/4 and throw another bottle in to really get it clean! Thanks for all the input.
