Occasional Oil Pressure Light for 2-3 seconds in my 318. Should I panic?

Just an FYI about the confusion about the difference betwee 1/4" clearance and 1/4" interference.
Definition:
What is the difference between a clearance fit and an interference fit?


"Clearance fit: In this type shaft diameter is always less than hole diameter, enabling two parts to move when assembled. Interference Fit: In this type shaft diameter is always greater than hole. In this case there is always overlapping of matting parts. It is type of tight fit."
Translation: interference- it touches, clearance- it doesn't.
