Found a video clip of the F80 M3. I called it an M4 in my original post because in my brain an M4 should have 4 doors and the M3 was originally a 2 door. Thanks for rustling my jimmies with your wonky naming structure BMW

Interesting, not where I thought the off occurred when you mentioned it. Looks like compared to the prior lap he was into the rumbles on exit from T7, got on the gas while on the rumbles and hooked to the right onto the tire wall.
Text mentions he had the traction control off. Wonder if he had done this from the outset or just for this session. Typically keep the nannies on for folks starting out.

Just noticed the instructor waving! Hahaha!

Yes I didnt notice this right away either. I remember him waving but figured it was just at a corner worker he knew. The instructor was great. Hope to bump into him again in the future.
The amount of 70+ year olds out on track was promising. Makes me feel like there may be plenty of time left in life to play

Seeing all of these old dudes at the track has made me decide that I want to be a driving instructor when I retire.

Picked up a new daily driver. I will miss the Datsun but the fuel economy was painful and I was ready for something new that had better utility for kid things and bike things.
Time to wash the M and put it away until a freak November warmup happens or Spring comes.
the winter to-do list:
-check/adjust valves
-check vanos bolts
-clean throttles
-replace throttle and cam sensors while the plenum is off
-replace belt tensioner pulleys that have gotten noisy in the last few weeks
-rotate tires side to side
-bleed brakes and clutch
-change oil
-glue C-pillar fabrics
-install the new Injen S54 intake coming out in December
-underdrive pulleys?
- code the brake pad warning light off??
-look for tiny oil leak which is probably the PS reservoir.

Valve cover is off to check VANOS exhaust hub tabs , check cam bolts, and valve clearances.
I had to see what I am dealing with first before ordering parts. If an exhaust hub tab is broken its no less than $400 to get back in the game with a used one on Ebay, usually people opt to spend about $600 on a cyro treated hub and another $150 on a modified oil pump disk that prevents future failure.
Everything checks out good so far.
Broken tab shown below for reference (Not mine thankfully). The tab can dislodge, cause timing to jump and cause unexpected meetings between valves and pistons.

The internet is full of forum posts of people with vanos hub failures, cam bolt failures, and rod bearing failures on engines with as low as ~36k miles as well as original engines over 100k without an issue.
General rule of thumb is to consider replacing rod bearings at 100k or sooner depending on use. Cam bolts are good once replaced, loctite applied, and torqued correctly. VANOS seals deteriorate fairly often. I hear that performance improvements can be felt in replacement where the seals were only a few years old.
I feel fortunate that this car is a 2005 as it seems to help the odds with some of the issues a bit. Unfortunately these S54 issues last well into the final years of Z4M production and the bulletproofing onky happens in the aftermarket world. That said, plenty of important improvements have been made after 2003.5 including the oil pump pickup screen (known to fatigue and cause oil starvation) as well as rod bearing and rod bolt diameter changes (11mm to 10mm) and bearing clearance changes.
