Step 1: remove #1 coil/plug and position #1 cylinder at tdc on the compression stroke.

Step 2: Remove upper half of engine mount, and anything else that might get in the way of step 3

Step 3: Remove tensioner inspection cover.

Step3: Compress and lock tensioner, then remove it.

Step 4: Using a 19mm socket, rotate the crankshaft counterclockwise until you hear the chain skip a tooth.

Step 5: Re-install everything and verify correct ignition timing and vacuum reading

This only applies if you skipped timing upon initial cranking, and only if it skipped on the crank sprocket, but I believe that's where it skips everytime.

 

how can we know 100% if our timing skipped a tooth?

 

Either check the base timing at idle with a scanner/logger or use a timing light.
