That, coupled with the unmistakable smell of MMO being present in the gunk everywhere in the head (and that gunk being the same consistency throughout), suggests to me that there was some reaction between MMO and a prior additive, between MMO and the oil/gas, or it is not always safe for long term use.
AGAIN, I am just sharing an anecdote. I use various additives that seem to me to work, and I avoid the vast majority. While I personally think that MMO is one of the products which here on BITOG gets way too much praise with almost no objective data to support its use, I admit that I keep a few jugs of it around because there are times (always in small engines, 2-stroke, or older/American engines) that it seems to make it run just a bit better.
Coincidentally, I have had great results using Seafoam in some known sludge-fest engines, especially the Toyota 5SFE, in combination with RP or PU/PP oil. It also cleaned the throttle body plate/housing, PCV system, and intake manifold. Yet, many people here don't like it.
Seeing as there's very little hard science in any of this, in fact it's mostly psychology (when we expect to see or feel a difference, especially if we are invested in the outcome, we see a difference whether it's there or not), I think we can agree that MOST OF THE TIME, there is LITTLE TO NO BENEFIT from anything outside the best possible oil combined with the best possible gasoline...
IMO you have given a fair and balanced account and it seems MMO was the primary additive used.
Of course this doesn't mean MMO caused the problem. It could have been another additives fault for being there at the same time as MMO.
But of course this just underlines the manufacturers reason to void warranties if additives are used. You don't know what will happen when you use additives. Engines and engine oils were not designed or tested with them.
Be careful about being fair and balanced about MMO though. There are a lot of people who get very defensive and consider any doubt a form of attack.
