Hi all, hopefully a quick question here. I just replaced the oil pressure gauge on my 51 8N. On cold startup, it reads right around 20 PSI (give or take a couple), and the needle bounces/vibrates...never holds steady. The old gauge read about the same I believe, but it didn't bounce; it was steady. So my questions:
1- Do I have a faulty gauge, or would something else cause it to bounce?
2- What is the "range" for good/normal oil pressure? (10w30, clean and full oil (no gas/water in it), not sure when/if engine has been rebuilt; if it has it was a long time ago.)
Thanks in advance!
