Ok

I have 86 rx-7 Euro model, (engine more like 85, distributor no cats ...). I hve problem that car is burning a lot of oil like 1 quart per 100 miles. But car still puls strong and there is no sign of engine malfunction. it smokes as i strat car and if i hold it on high rpm and let go of gas pedal. Then sometimes it doesnt smoke but strange thing is when i am monitoring oil pressure gauge somethimes is going up to almost to the max limit and another time is on half way beetwen 4-6 kg-cm3 on 5.000 rpm.

I need advise what could be worng and if there are internal problems shouldnt there be visible power loss since car is doing easily 110mph in 3gear uphill at 7.500 rpm.

Als there is strange beeping sound in cabin somethimes starting like i didnot turn off lights ????'

Please help
