    Precipitous drop in oil pressure at idle

    LOL, close but no cigar ... But an oil Temp gauge might help. It's a guess but the only thing is the motor is getting hotter & hotter [what is the water temp gauge showing as oil pressure is dropping?] That's why a oil temp might show oil getting hot... less viscosity as it heats up...

Some aftermarket pans come with a lower baffle... you could just make the upper one. BUT no one will see it so I would buy a windage that bolts to the bottom of the block. MPG had a...
