White smoke indicates the appointment of a new Pope - p'raps the cars getting ahead of events...

NEW BOY.....if you wish to check your compressions and do not
have a compression tester then you can get a good idea by using
the starting handle (you should have one). With the ignition OFF,
and car in neutral you should insert the handle and turn the engine
over. As you compress the air in each cylinder you will hear the
faint hiss as the compression escapes wherever it can. All four
cylinders should offer roughly the same resistance to the turn of
the handle so,if one or more are noticeably easier then you might
well have a problem. This does not,of course, give you any sort
of pressure reading, just a comparison of all four cylinders.

Good point - the starting handle test ! New float needle valves are just that - the seat is not replaceable that I know of ! How long does this white smoke last - it's normal for a few miles with a cold engine - take it out for a good hammering - now does it still have white smoke ??

I replaced mine on my HIF44. It just unscrews (unbolts?) with the correct small box spanner although I think I used an open-ended spanner on mine.
