OPS light on briefly @ startup

[RobE30]

When I first start my car the OPS light comes on (longer than its supposed to) then goes out. I'm planning on installing a new OPS to try to remedy the prob. Any other suggestions if that doesn't work? Also does anyone know anywhere I can get an adapter that screws into the stock OPS hole in the block and "T's" off to a M12x1.75(stock OPS thread I think) and a 1/8 NPT (size I need for my autometer OPS for my gauge)?

you need to check your oil pressure maybe it's a little low that's what it take alil while to go off.
