Read a few articles & watched a few youtubes on the VANOS. Sounds like an interesting avenue to explore, and I would like to get some readings.

Sounds like the VANOS is especially sensitive to oil viscosity. I admit I am way behind on my oil change schedule, and I could see that possibly affecting it. Yes, I know, I know. But, I was in an awful accident last year, spent a week in the hospital, and literally almost died. Thank God I didn't, but I got behind on a lot of things and I'm still trying to catch up. I do run Castrol Titanium 5W30 full synthetic though, and normally change annually or at 20K. It's been way over a year but the wife really doesn't put that many miles on it, so I really haven't been that concerned about it.

Give me my reprimand about the oil, and no doubt I need to go ahead and refresh it and the filter, but I do have a little trouble imagining that the VANOS would affect only Bank 2.
