Yes that is correct. As you turn the housing the direction of rotation you are retarding it. Turning the distributor shaft counter clockwise will do more of the same.
One tooth refers to the number of teeth on the distributor gear. I don't know the exact amount but there are 12 or 14 teeth so you would rotate 1/12 or 1/14 (or one of however many teeth are on the distributor) of a rotation.

Pro tip: When you turn the distributor back one tooth turn the oil pump driveshaft the same amount. If you don't you may run your box of foul language empty before the distributor seats on the manifold.:D

I never touch the oil pump drive gear. Lay the distributor in there far enough for the distributor gear to engage the cam gear and bump the starter. The distributor will fall right into place when the oil pump shaft slot lines up with the distributor drive tang. Way easier than trying to fight it with a long flat blade screw driver.

I have a 98 5.7 vortec.

I installed a new distributor today.

Using torque scanner I added a pid for cmp offset. The best I could get it set to was 5.8

From what I've been able to find I should turn the distributer clockwise to compensate for a positive reading.

I turn it clockwise as far as it will go and the best reading I get is the 5.8.

Do I need to pull the distributor back out ?

I read that I need to pull it back out and turn the rotor counterclockwise 1 tooth. Is this correct and how far is " 1 tooth"?

Im in a similar boat. When u mention torwue scan is that the phone app? If so how did u set up the pid? I havent been able to find any info on it.

I apologize for the thread jack.

Try the early for escapes. Especially the 4wd ones. Gotta take front axle out n i think subframe loose. Needless tk say i farmed that job out to someone more advanced.... And less lazy.

Or just about any FWF Nissan 3.5L. First step, evacuate the a/c. 2nd step, remove the a/c compressor. Then you can get to the alternator mounted under it. Luckily the alternator usually lasts the lifetime of the car on those.
