Thanks for jumping on the forums. The audience is small at the moment, but we will hopefully get more folks who can offer technical thoughts. I am not as familiar with the V6 but on the B230FT turbo there is a plug near the front of the motor, under the side of the water pump, that is for oil pressure. I’m sure also long as the prop is fully seated into the block with exposure to the oil you would be fine. Where would you add the gauge if the dash would’t lend itself to another indicator?
