What would happen if I used MMO through the PCV?

The newer Hondas have an air injection port at the fuel injector, which may be another place to add "stuff". Although, I'd be more inclined to use LC for this rather than MMO. At least that way you can ask a real person for advice as opposed to a phone tech geek.
Bad idea. It would smoke like crazy. Its an oil. It is not a quickee flush product.
For "engine vacuum" type cleaning, use one of the FI cleaners, flush products, or their equivalents(competitors).
I've run seafoam, b12, kerosene, biodisel, ..... through a vacuum hose as a carbon remover. I'm betting that FP, any topend FI cleaner,.... would also work pretty well.
Remember that this will only clean what is downstream of the vacuum source. Do this on a cold engine since hot engine caused product evaporation will be an issue.
I wouldn't use Lucas UCL, Marvel Mystery oil, or LC in a vacuum decarboning.

I wouldn't bother doing it unless I had the engine up to operating temp. I want those pistons and valves as hot as possible. I would prefer to do the whole intake induced purge thing under load, if possible.
Now if you want to dump the stuff in and stall the engine (still hot) and let it sit over night ..I'd go with that maybe, but I think you would lose the shock effect of any agent introduced doing it on a cold engine.
Just my opinion.
Your engine will explode like a nuclear bomb, vaporizing you in the time it takes an electron to circle the nucleus of a hydrogen atom. . .
OK, maybe that won't happen, but all of these "induction-sucked" cleaning strategies get me thinking "hydrolock". I know that some of them work, but then again, I'm not sure when you creat a danger of destroying the engine by hydrolocking. MMO is a reasonably "thick" liquid and I'm thinking that if any substantial amount of it made it into one or more cylinders, you might have a problem. Or am I just misunderstanding this whole HL problem???

ekpolk ..you can't truly hydrolock an engine that way. I've done it doing a purge with ATF ..but not while the engine was running. I "induced" the ATF via the PCV line ...and then sat the ATF jug, with the hose still in it and submerged in the engine compartment with the engine off. While waiting my 20 minutes ...the ATF syphoned into the intake ..found an open valve ..and filled the cylinder. A .2 second crank of the engine ..and it was hydrolocked. I pulled the plugs and spun it around (nice mess) and all was good.
That's why all the cans of any type of purge say DO NOT CONTINUE TO POUR AFTER THE ENGINE STALLS.
I don't think that you can "induce" enough liquid via the PCV hose to hydrolock the engine given the large amount of air you're also pulling in through the horn. This is sorta like "ventury" induction.
I'm uncertain of how MMO would work here. The old MMO "inverse oilers" dripped MMO into the PCV line (dripped is a misnomer- it was drawn in -in very minute quantities) ..but I dunno of all that much at one time. I've used ATF ..and it did a very good job...but produces a massive white cloud ..as I suspect MMO would. ATF (at least the cheap stuff that I used) never left any residue ..but I dunno about MMO in that quantity.
I might try this when I'm in the mood ...maybe a 50/50 mix of ATF and MMO. I'll do it on my daughter's beater Taurus and see what happens.

I would think that the worst thing that could happen is that you may have to change the plugs or something if MMO leaves undue residue. ATF burns cleanly (again a massive white cloud).

Well, next time my daughter is back from college (if it's not too cold, I'll maybe try this (she'll be due for an oil change anyway). I'll let you know what happens.
