After having driven 2000 miles in ffr3474 the oil pressure guage has developed a severe vibration.
the needle vibrates so hard that it is just a blur in the 50 to 70 range. It stay fairly steady with lower oil temps. Autometer vintage guages, mechanical. Has anyone had a guage problem or do I have a big problem coming?

I think I remember hearing that this is sometimes caused by air in the oil pressure line to the gauge. I'm not sure how to fix that or get rid of the air though.

You WILL have a problem if you don't stop the flutter, due to rapid wear of the gears inside.
You could install a guage snubber in the line, or even two or three in series if necessary.
The ones I've used are 1/4 FPT x 1/4 MPT.
