Interesting thing happened on a 250 mile drive through the mountain twisties last Sunday. After taking a particularly long and tight turn very fast(can't remember if it was a right or a left), the rev limiter came in just prior to the second cam switchover, prompting a quizzical 'What the Hell' to emanate from my lips.
I'm wondering if there was momentary oil starvation caused by the oil being forced to one side of the sump, beyond the pickup's reach, thus causing the ECU to shut down the second cam range, forcing an inspection. I looked it up in the manual, found nothing that indicated this would happen. I read an earlier post on this forum that said there was a fuse for the VVTL-i system, so I decided to inspect that. I pulled the fuse, but before I could see it's status I dropped it behind the engine. D'OH!
Fortunately, the am/pm mini mart had the right fuse, so I popped it in and was on my way, VVTL-i now operating normally. I won't see that fuse until my next oil change, so I'm just wondering what you guys think.
Is the sump in this engine not baffled? This would have to be a major issue for track cars.
