I'm confused by all this talk of bleeding the oil pressure gauge. In 25 years of Austin 7 bodgery, I have never found it necessary.
A while ago, I had a gauge that pulsed on low revs and quivered as the revs climbed. It was suggested that the lack of an air bubble was causing the wobble as the air has a damping effect. As the pressure rises, the air will be compressed anyway.
If it responds to tapping, I'd be more inclined to think it was a little bit of crud on the tiny mechanism that drives the needle.
Just my tuppence worth.
Oh and if anyone has a drip from their gauge, I still have some tiny leather washers for the end of the tube.
