How to turn engine over by hand

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

Hey Rat, just finished doing a compression test on my 2011 Dodge Charger R/T with the 5.7L Hemi V8.

All cylinders except cylinder one were very close to 160 psi with the throttle body fully opened, and all of the cylinders having one spark plug removed.

However, cylinder 1 is showing 0 psi. So I am getting ready to do a leak down test on cylinder 1. I was plannning just to use the old school method with a ballon to find the compression stroke, and then find the exact top using something long down into the cylinder while manually turning the motor over.

Is there an easier way to find TDC? Also, is there an easy way to make sure I am still TDC as I move from cylinder to cylinder if I plan on testing all of them? May not be a bad idea to do it since it’s basically all set and ready to go.

Seems like you know much more about this than I do. Any information you can provide would greatly help.

Thanks in advance
