I like MMO but don't think I've used it as a soak. I get great, measurable results using it as an UCL added to gas.
I have used SeaFoam a few times, I've made my own "homebrew" seafoam from a recipe I found on the web also (white gas (camp stove fuel), acetone, kerosene I think). Last time I think I used Chemtool B-12. Because it's a progressive problem, I can't say what was more effective with any real certainty.
Vehicles with this issue usually have a corresponding varnish issue as they sometimes get low on oil and then the oil runs hotter with the attendant consequences. I run a kerosene flush every oil change. It helps clean things up, too. Between those and running a quality synthetic (I like M1 10w-30 HM), the usage trend is downward slowly.
If the heads could come off of this vehicle w/o pulling the engine, I'd have done that a year or two ago. I'd pull the heads, take out the pistons, de-carbon them and the rings and grooves. Then your drill additional drain holes in the grooves and skirts, put it together and the problem is gone for good. At 1qt/1,200 mi with the trend downward, I'll stick with this proceedure vs. pulling the engine from the vehicle to get at the pistons.
