12A dropping oil pressure
I've never been on a forum and couldnt get the archive search to work, it said failed search for a couple of seconds and the I got a different thread.
120K miles, all original engine from 84. Always had 20-30 lbs pressure at idle and 60 at 3000rpm. Last drive I have 30lbs that did go to 60 and this AM nearly 0 after unattended warmup (how stupid), then up to 50 and dropped to 30 within 1 mile. I think I have a great mechanic but would like to learn a little on my own, but don't know enough about engines to start to guess. Wish I could figure out the search engine for the archives. Thanks for any help.

On my previous RX, an '82, I got a consistant 5kg/cm2 when crusing and 6.5 to 7 kg/cm2 when accelerating/revving hard. At idle, it tended to hover at 2kg/cm2. I don't know how that works out to psi, but there you go. My current '79 doesn't have a oil pressure gauge, so I guess I'll have to trust that everything is working smoothly under there.

Dirty sending unit
The last oil change was done by a guy that let the oil run out of the filter and over the oil pressure sending unit right below it. I cleaned the connection and all is well.
