OK, here are some more accurate checks on the problem:
Steady tick over at 800rpm.
Slight blue colour to exhaust. If run in garage it soon becomes
uninhabitable (as does the kitchen and the whole of the rest of the
house 'cos there is an interconnecting door which isn't fume proof) -
not popular with "her indoors".
No revs change when I remove oil filler cap. very slight, I mean only
just detectable with the help of imagination, positive pressure at oil
filler cap.
Steady stream of air from end of disconnected crank vent hose, can
feel it against my face, but no colour in it - i.e not blue even when
directed across white paper.
When I blip throttle there is a good belch of exhaust, quite blue but
also whitish cloud. (but it is not steam!) Oily smell.
Definately consuming oil, about 1/2 pint per 300 miles I would guess.
Remember, rebore, new pistons and rings 3000 miles ago.
Reconditioned head with new valves and valve guides this weekend
