I bought my 2006 Rubicon Unlimited with 80k and found out later that it had an engine replacement done at 60K by PO. I don't have any info on what was done or why. Do you think this part would have gotten replaced with the engine swap? I think it was a long block from Jasper. Hate to pull it just to check it.

First, is it a LDI part? If so, it is the factory design, whether or not it was replaced when the engine was.

Only way to know the condition is to pull it.

On those last pics from 2006 sport, is that considered that bad? I'm no mechanic but for 85K miles, I'd expect a little wear. That doesn't look that bad to me. Hell I'll be super happy to get 85K on the original part.

There should be a smooth shiny spot on the gear in the center. That one is too long and it is rough.

My '92's distributor gear didn't have that much wear at 200K plus.

I replaced my '06's at 115K when the cam sensor went. It had some wear, but not as bad as the pic above.

Yep, Way too much wear for only 85k. As soon as I threw the P0016 code I ordered that part because I knew that the gear was probably worn down to the point where if I didnt replace soon it was gonna do more harm than good.

I dunno how much better the Dorman part is, but anything will be better than what I have right now. And i might send my old one to the guy in here (can't remember name) to do the mod for it as a backup.

Try spinning the shaft. I bet it’s tight. Excessive drag will eat up the gear like that.

Anybody remember this from page 1?

The hope is to limit this thread to only a few pages of actual information regarding how to handle this problem

So I got the Dorman unit today. Lined up the holes before I installed but I forgot about the TDC deal and installed it. So I kept it in there and aligned engine to TDC. Can I take the OPDA back out and align the holes again? Because the bottom hole is on the left and the top hole is direct opposite on the right.



Edit. Never mind. I got it haha

Okay so everything is installed. No CEL on warm up but when I go to gas it, like revving it, it hesitates and acts like it's going to or it has cut off. Assuming that's my timing.

Given the problems reported here & elsewhere with some of the Dorman sensors I would put the old sensor in (check the sensor-to-wheel clearance against the Dorman one) & see if that fixes it.

No I'm an idiot and double checked too much and what I thought was TDC was 180 degrees off of TDC. don't know why I didn't think of before


I'm embarrassed as all hell but **** it

You are just enough out of cam / crank sync that the computer puts it into limp mode. Limp mode will do just that (cuts at 3k rpm). The exact thing happened to me when I installed my Dorman. I took it to my buddy who has a Snapon scan tool that can read cam to crank difference. We adjusted it until the difference was zero. Fixed my problem. The Jeep FSM talks about this procedure. The dealer uses the DRB factory tool to do this for them.

I used the original sensor in my Dorman. The Dorman one was intermittent.
