You know you're having a bad day when...

[dnb]

you're at the rollers tuning a friend's car and on the last run of the day the coolant air-bleed screw parts company with the head, giving the car, the dyno and my laptop a good shower. It would have made good power on that run too

I suppose it's better to find these things out before the track day.
Sod it. I hate cars sometimes.
