Oil pressure

Mk1 caddy 1.6 carb

Started her up for first time properly today.
I have noticed that with ignition I have oil pressure light and when I start up the light comes on dull at first then gets brighter. Any thoughts on this please.

That is at idle?

With just ignition - no light
Idle - dim light
Rev up to 2500-3k - light gets brighter

Need to know the bar rating of the oil and temp.

I would suspect that the light with out the Buzzer is from the can on the side of the head.  If you a buzzer then I would suspect the white sender on the oil filter flange.

Could also be bad grounds, but well first things first.

If you are thinking of replacing the Senders, on the can on the side of the head that is the low pressure at idle and the oil pressure gauge sender.  There are cheap ones out there, and they don't work…. the usual price for one that works is anywhere from 40-75 dollars.
