How to turn engine over by hand

[Boony405hp]

Dave - you dont have to worry about losing TDC when turning it over - the ECU picks up the correct cylinder sequence off the tone wheel - Still....it doesnt hurt to mark tdc when you find it....in case you ever want to degree a cam...

Which tone wheel is this specifically Mal? ie. where is it located?

Theres one attached to the crank - and one on the cam - we call it the reluctor wheel or trigger wheel

Like Rat Patrol Said,

It is attached to the crank INSIDE the block. The reluctor wheel sensor bolts to the block. You can see the ring in this picture. It is to the right and on the outside of the bloc you can see where the hall effect sensor is bolted.

The one pictured in Rat Patrol's post is the Cam Shaft Position sensor. Both the Camshaft and Crankshaft position sensors are hall effect devices that run off of 5 volts. FYI. your motor will run without the camshaft sensor being hooked up. But it won't run without the crankshaft sensor.
