Okay, I wasnt able to type alot but heres my problem. I bought the car and the oil gage would sit past zero at idle. but when you are driving/reving the car, it will go up to 60psi. The guy who has owned the car sence 1993 said its always been like that. Well today I get around to changing the oil, (it needed it bad). When I started the car, the oild pres is sitting right on the zero mark now. and goes a little past 60 while driving/reving. Im thinking it could be an oil pump going bad or a cloged screen on the filter, but im scard that im not getting oil to my rotors. I dont want to blow my motor. =(

i doubt if that's your pump. it either works or it doesn't and in 21 years, i've never heard of one failing on a rotary. i'd bet your problem is electrical. start with the sending unit.

Are you using the stock gauge? I would hope not, those tend to be a little inaccurate. Get an aftermarket gauge and double check. Mine sits around 20 at 1000rpm, and goes to 85 at about 4000rpm.

Yeah it is the stock gage. Where can I locate the sending unit?

I thought about insailling an aftermarket oil gage, so I might do that really soon.

Stock sender is the 'mushroom' shaped part under the oil filter on the side of the block. Since you're hitting 60 psi, hopefully by 1500 rpm, then oil pimp is fine. If you go with an aftermarket gauge, you can flush cut the 'button' off of the 'mushroom', tap the 'stalk' for 3/8" NPT thread. I have no problem running the tubing into the cabin, make sure there are no kinks in it.

In my signature is the link for the factory service manuals. If you intend to do any work on your vehicle then you need to down load a copy for reference. Everything you need in in that FSM.

First thing that you do is clean the connector that attaches to the sender unit and make sure it is tight.
You may have a bad sender or even a bad gauge.

You have options here. You can perform a oil pressure test. You can just buy a new sender unit and see if the reading changes on the gauge.

You can buy the proper adapter to put in the block so that you can run an aftermarket gauge ( Napa sells the adapter).
It goes from 1/8 BSP to 1/8 NPT.
