My motor leads a hard life.
It is my first 911 motor build and other than machine work and the heads, I dodit all meself.
It gets driven little, then with minimal warmup we're off to AX. It is seldom up to full operating temp for the first few runs.....I gotta find a better way to do that. Then it gets to bounce off the rev limiter as we search for gud shift points. Then (maybe) the 7300 chip goes in.
As part of the winter project, adjusting the valves was part of the sequence. It ran all season on one adjustment done about this time last year.
All 12 of the valves were .001 loose......amazing. No rocker shaft creep, lovely even wear on the cams.
I got the cam break in right, if nothing else.
