Engine runs smooth and engine has oil pressure and no leaks, I've put in a new oil sensor and had the oil changed and filter and the light still comes on and gauge reads 0, but at times the gauge will shoot up to 40psi then it will shoot to 0, at times but engine purrs with no knocking or anything it's driving me crazy cause I've got oil pressure and truck is running great
