Winterize 1998 5.0 Gi

its not so much the EFI (but that does play into it, depends where the sensors are located) its more the design of the intake manifold. some of them have "pockets" that the fogging oil can collect in, and then when high enough RPMs are reached it can all get into a cylinder at once and bend a rod.

I can see the problem of spraying a Mass Air Flow Sensor, an Air Temp Sensor, an O2 sensor, and a catalytic converter, but not all marine FI engines have those.

What a 2 ounce glob of oil being pocketed, then suddenly all released? Sounds like a real crappy design for an intake runner.
