I was reading the procedure for Seafoaming our engines and I kept thinking in the back of my mind wouldn't this flood the engine? I realize people successfully do it all the time and I want to try, but how does pouring seafoam into the chambers not flood the engine? Can anyone explain? I want to decarbon the engine, but I afraid I'll mess it up and need a tow.

 

simple physics.

#1 your not pouring it down the engine your letting the engines vacuum pull it in.

#2 because the e-shaft sensor is unplugged the ecu has no idea where the rotors are positioned and as a result will not fire the engine. (can't remember if thats the fuel cut out or what but it's from the e-shaft sensor) since there is only the strength of the starter cranking the rotors and the law that water/liquid will not compress the strength of the starter will not pull more seafoam into the motor than can fill the space during the smallest phase compression. so essentially you could use i can per rotor and keep cranking, once it's full it wont crank anymore. But i suggest you don't do this.

#3 th seafoam will disolve the carbon inside the rotor housing and rotor face. i haven't seen the chemical make up of the seafoam so i can't say but i believe that it will evaporate eventially.

 

my friend and i did this and we spilt some on the header and when we started the engine the the header got hot it started smoking.... just burned off but funny to watch smoke coming threw the vents of his hood.

 

Liquid, in and of itself, actually improves the compression. People have used anything from engine oil, to ATF, to water, to windhield-washer to help unflood rotaries.


Lots of raw gas won't work because then the air/fuel mixture gets funked up. I'd guess the vapor pressure of SeaFoam is a lot less than that of gasoline. So that when you start cranking, a decent A/F mixture is pulled into the chamber, and the residual SeaFoam serves to build compression without disturbing the combustability of the mixture so much as to prevent a start.

ya, I don't know the makeup of Seafoam but by principle of how you fill the engine it won't be flooded. Esp since you are essential pumping out the old fuel and bringing in the seafoam. Now I think seafoam is combustible so that would ease the flooding issue as well. Now when we used to clean the old rotaries with ATF, that was a different story and required the pulling of the cat. Oh man the smoke that would pour out of the cars made the seafoam treatment look minuscule lol. That also used to foul the plugs up a big so had to clean them or replace them right after. But I have been curious if it would work the same as the Seafoam. I've watched cars with little to no compression come back after an ATF treatment, but I've seen the same with Seafoam.

 

maaaaan im so glad you said that...i got home and i thought i screwed up cause i did it today (first time) and my car was smoking n thought something was wrong cause the engine light was on too,...thing is.... i actually ran to get my hose and lightly sprayed under my hood.....
