Gary, I've looked into catch cans for my daily driver but the full kit with adapter plate etc is around $400. A water/methanol injection system is a bit radical for me. Mine's a turbo that I drive hard at times and I change the
oil every 6 months. I'm going to start dumping a $15 can of Subaru UEC (upper engine cleaner) into one of the vaccum hoses and run it for a short while prior to every
oil change. This is what a couple of the dealers have offered as a preventative measure when I've asked about the problem. Except they want $130 for the "job".
Apparently Toyota is now using an additional injector to squirt fuel into the intake runner on their direct injection engines, in the hope that it will solve the problem. Sounds like a good idea to me.
