i feel compelled to mention that: I've noticed the same on mine. The oil leaks slowly from the dizzy and onto the pneumatic lines and, more critically, the coolant line that join the bypass line around the back of the engine. Causing the rubber to swell and over time become weak, leading to premature failure. Eventually splitting and letting your coolant out. That or the pneumatic lines slip off and you get an air leak. If it was an easy fix id definitely fix mine but honestly CBF pulling the dizzy, for now i just keep a close eye on the components beneath it.
