I'm wondering if the combustion process is what makes Seafoam work...

you understand how a rotary engine works right?
Yep, i know - I'm in no way an expert on rotary's, or pistons for that matter lol, but its not rocketscience either. Im helping my coworker rebuild his 3rd gen.

I also suggested that seafoam was bad for an engine's seals - based on what i found with my piston engine.

Was only submitting some food for thought on my personal experiences with seafoam. Seafoam doesnt know if its a rotary or not - they both have oil seals and bearings, and if seafoam can screw up one type, there's no reason why it cant screw up the other.

Unless you put carbon seals in there...they are metal. Steel I believe.

Not really...
Understanding how things work is the only way you can determine if A is bad for B

if i was going to seafoam a motor, i'd leave only leave it in for a couple hours at most and then clean the system out completely. but most likely i'd never do it in the first place
Plus, the side seals are rubber - and exposing them to what is effectively a solvent is likely to cause them to swell. Which will initially cause better sealing. Then, increased wear from being swollen will couple with them shrinking again over time as they "dry out" to leave them in poorer shape than before.

I'm with those who say that if you want to Seafoam, change the oil right away.

honestly anything that it hasn't gotten off by now isn't gonna come off, soaking the rubber parts in your motor in solvent for this long will be really bad, please take it out, look at what everyone is saying

I got over 300 on it now. I am replacing the filter and oil tonight.

I have to say. I have nothing, but good things to say about SEAFOAM.

Thanks for all the advice.

I am going to try a MMO mixture tonight.

I put Seafoam in my oil for 200 miles on a N/A S4 Stock motor. That was 2k miles ago. I have no complaints. A friend of mine who drives my car asked what I did differently to it(had a stronger pull), so it must not be a placebo effect because he didn't know anything about it.
