adjusting valve clearance

If the manual says cold, it means stone cold, like first thing in the morning. How are you going to measure "slightly"?

(series engines tappets are 10 thou hot or cold, which I have never really understood. Surely it's one or the other?)

Don't risk it - do it next time you have a cold engine.

If you were really cunning, or bloody lucky, one bit that expanded "up" could be countered by another bit expanding "down".

on what?

the plate on the top of my 2¼ says "valve clearnaces 0.010 engine hot or cold".

just means that the expansion in the head and in the valve stems is the same. You can adjust it at any point.

It would help if we knew what engine you are talking about. If it is the Series 2/3 2.25 petrol or diesel, it can be set hot or cold or anywhere in between, as the expansion of the head and the valve gear compensate for each other. Although my experience is that there is about one thou increase in gap when hot. If this is not the engine you are talking about, then set as specified in the manual (some engines I have worked on specify "hot and running", which can get messy). JD

and rather silly. mind, the haynes series book says "cold", despite what the engine itself has on it.
