oil pressure

my oil pressure gauge when i first start the car is normal it moves around alot at first but after awhile it goes to 0 and stays on 0 or a little above. it uses no oil between oil changes. and leaks no oil. it runs great except for the boost problem that noone seems to be able to help me with. this is a 1993 twin turbo it has 113000 but i have papers from previous owner where the turbos and engine was rebuilt at 60000 but anyone can make papers. didnt care cause i got the car at a good price.

you have a problem if your rotary doesnt burn oil..

its never low and clean as a whistle but i also change it every 2000 miles.

yea that is deffinately strange... can't think of anything that could cause it right now...

could it just be a bad gauge

Sending unit - No ?? Ground it out and see if it works.

I'd check the sending unit, then the gauge. I doubt its the front o-ring, if it were, the engine wouldnt have lasted as long as it has.

Hook up a mechanical gauge briefly to make sure
