Thanks for the suggestions.
I take it that for the pressure to be low the ball in the pressure relief would have to be held off it's seat or the spring has broken.
I'll try taking it out once the weather warms up a little but what's the best way to check and clean the seating. (I'm assuming it won't be easy to see, especially with the engine in the car). Do you think liberally squirting WD40 into the hole after removing the spring and ball would help achieve this?
I suppose it would also be sensible to get a new spring and ball anyway.
John.
