Guess what I broke?

Let's hope this is the first and only episode of "Guess what I broke on the Yaris today!"

Drove to one of our local autocross sites to instruct at the BMW teen driver car control clinic.  Got there early and the course setup was already done, so I took the opportunity to do some acceleration runs in a pleasantly controlled environment (and with a favorable temperature... probably around 65 degrees).  Did several runs, and found that 0-60 is repeatable at about 8.6 seconds, with a best of 8.4.  Cool!  Way better than I expected.  Quarter mile time was about 16.7, which isn't bad at all considering the best I ever got out of my '96 Miata was 16.1.  So, I'm happy about that.

Played a little bit doing some test runs on the course, and did a few demo runs for the students, then parked the car for the rest of the day.

So... what broke?  Well, I noticed a rattle on the way home.  Quickly pinned it down as being the tach.  At first, I thought it was the mounting of the tach, or maybe even just the flimsy top of the dash somehow rattling.  But... no.  The tach is broken internally!  The whole mechanism is loose inside.  It still works, but that rattle will drive me nuts and I'd have to kill Jeff before the end of next week.  That would be sad, so I guess I need to fix it.  Unfortunately, I don't have time to order a new one, so I guess I'll take it out and see if I can take it apart and tighten whatever is loose.

It's always the aftermarket stuff that breaks.  Always.

Oh, and did you know a Yaris gets a healthy 2nd gear scratch when doing a full-throttle acceleration run... even with grippy tires?  Yep.  Every time.  Hmmm... do you think the clutch is covered under warranty?
