Adherence to the specified temperatures make it completely unnecessary to define the temperature subjectively.

Additionally, the referenced spec was for any temp above 45 degrees C. (The 617.95 Engine Manual lists 60 degrees C as the temp associated with the higher clearance specifications.)

I was sitting around reading the 617.95 engine manual last night... and I have not converted the C to F...
but is there a possibility that NONE of the recommendations are for an engine which has recently been RUN....
but are for engines at rest in various temperature CLIMATES...
Think about it before you answer.... as I have another fact from the book which makes me think this might be possible....... ( all this is speculation waiting for my conversion from C to F in the thought process )....

much much easier to go from one cam up to the next. 3 -4 short turns on the ratchet ( 27 mm socket on crankbolt) and the next valve is lined up. look at the intake manifold to see if it's in or out.
after setting clearance verify that a larger sized feeler gauge doesn't go in too.

There is a spec for extreme cold ambient operating conditions. The other specs apply to the engine temp at the time of adjustment, not to the operating environment.

Allergies + migraine.

I always get the best/most consistent and durable valve adjustment after the engine has cooled to ambient overnight.

I don't see why it would make a difference whether you adjust hot or cold ALA YOU USE the RIGHT specs for the temp. at which you're working.

A cold motor is a cold motor.

A hot motor not running is constantly dropping in temp therefore the proper valve gapping is always changing.

The proper way is cold. Think about it.
