Hello, Bob: Not a bad idea, but I wonder how much the pressure differential would affect the apparent oil level. There is bound to be a difference depending on the crankcase pressure. Regards, John "Seahorse" >By modifying the dipstick tube to extend down into the crankcase below the top turbulent oil level, one can eliminate the splashing effect and check the oil with the dipstick as is normal. No need for a Murphy gauge that may void a warranty.
