I drove and painfully kept a Nissan Murano, '03 VQ35DE with CVT on the road for 15 years until traded off.
Numerous valve bank position sensors later, and finally a situation where P0420 codes would appear, disappear, reappear...wax on and off without reason... was traded. The CVT was solid on it, but I didn't believe the manual or the "lock" on the tranny dipstick. She got dumps and refills every 30k on that CVT and was at the 200kMile mark when sold with original gearbox.
The most...
...salient...
...frustrating...
...OMG, put my privates in a vice moment...
That crank case oil dipstick was tough as bawlZ to sort out. As I've read in the past and in tech service manuals from Nissan themselves? The oil galleries as they drain also used the dipstick tube as a return path. So while engine was hot, but settled for 15 minutes was the time to check levels. But you had to dip, wipe, dipe, wipe, ad nauseum until you got a clear reading. It was double frustrating after a clean oil change.
