So this weekend, all the water went out the tailpipe.
It took the driver 3 laps to notice this
(he's been sacked)
but the only thing I found wrong was that the exhaust valves were making
their own reliefs in the pistons (!!!)
The engine builder's been sacked, too.
I didn't have a very good straight edge tonight
(I sacked myself)
but the head is surprisingly un- warped. Based on a bit of aluminum angle I had lying around.
