I just noticed that my car has a 96+ timing cover on it with the CPS hole plugged. This makes sense as a few years ago when I was doing my cam install I found there was the crank reluctor wheel in front of the timing gear. I removed the reluctor wheel and ran the car until now and never had any problems.
So measuring the hub i get 3.5" or really damn close to it. The long hub is 3.519" so I guess this means I've been running the wrong hub for the last 20k miles.
So my question is do I really need the longer hub? or can I just put it back together like it is? Does the hub hold the crank timing gear in place?
I guess the easiest way to fix the problem would be just reinstall the crank reluctor wheel.
I just remeasured the hub more carefully, looks like it is the longer hub. Its right at 3.6". I also checked and the timing gear is fully seated onto the crank, it cant go back any further. So I think I'm good.
