Oil pressure help

What is the oil pressure suppose to be at while at idle?

How far below 30? Of course that's all useless if you haven't verified it with a mechanical oil pressure gauge.

The FSM and Haynes contain oil pressures at various RPMs.

The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.

But really, the stock gauge is not very accurate at this point because the senders are getting old and tend to fail.
