Hi all,
could you please help me to find out why and how to fix this... Thank you

the oil pressure light blinking at idle and at all RPM

Van description: 1989 tintop syncro, rebuilt 2.1 WBX with about 5K miles, a
lot of peripheral items were replaced at rebuild including the low and high
pressure senders. Mann oil filter, 10W40 dino oil in winter, 20W50 in
summer. 10cent (Chris Corkin) oil cooler with fan.

The Problem: The oil pressure light always blinks continuously when I turn
the ignition on and went away when I started the engine.... until about a
month ago... it blinks once, (not blinking continuously as before). My
mechanic said the blue oil pressure sender is bad... so I ordered a new one
and put it on. And now it blinks continuously, engine running or not at all
RPM, cold or warm engine... I check the sender wire, looking OK the white
plastic connector is OK too.

What else to check? Could the high oil pressure sender be bad too? Is it
safe to drive about 20 miles to the mechanic or get towed to him?

thanks in advance
