Engine rotation on an engine stand
 

I'm going to mount my 3.0 on my engine stand in order to work on changing hoses & lines, oil leaks, heat exchanger removal etc.

My question is: will I screw anything up with the CIS if I'm rotating the engine sideways & upside down with the fuel injection system still attached on top? I'm thinking about the potential sensitivity of the fuel distributor and the sensor plate assembly.

No.
