I would put a gauge on the engine first to verify it's reporting correctly. The oil pressure relief valve could also be stuck causing this problem. I would check that. If that isn't it, then I would go to the oil pump. It could also be a bad crank/rod/balance shaft bearing leaking off your pressure. I'm not really sure if there is a place to put a gauge on the engine before the relief valve or not..maybe someone else knows that.

I don't think we can stress enough the importance of not running an engine long with low oil pressure or knowing the condition of the timing/balance shaft belts. If these belts break, then you will have some major engine damage. To replace the oil pump you will have to remove these belts, so that's a great time to replace them....along with the rollers, water pump and front oil seals as already mentioned.

Should be a fun project for you and check out clarks-garage.com and 924.org for more information on your car.

Good Luck.
