Maybe this isn't the right place to post this, but can cold weather driving help with cleaning the valves on a direct injection engine? Emptied my catch can the other day, and just like every time this winter it's filled with what looks like a lot of water. Summer was different, it appeared to be mostly oil. The school of thought is that water can clean carbon deposits - at least that's what I always heard...how we used to pour a little water down the carb and it'd clean the carbon off those pistons.
I'm running Pennzoil Platinum 0w20 in my truck, it calls for the 0w20. I installed a catch can because I was concerned about the amount of oil that seemed to be tracking into my intake (truck only had 10,000 miles at the time). I have 26,000 miles now.
But when I'm emptying this can and I see that mixture of water and oil...and when I see that white smoke blowing out of the tail pipe all the way through my 40 mile commute (it's been real cold up here) I think...is the PCV introducing a fair amount of water into that intake, onto the valves...and is it actually doing more good than harm? And believe me there's a fair amount of water...enough to freeze the contents in the can solid (it's been bellow 10 degrees every morning this week....-3 on Tuesday).
I know I'm reading into this a bit too much. And I know direct injection has gotten into my head. Lol.
