Got the gear from Advance Adapters. Hope to do the install this weekend.
What do you do between meetings? Clean and paint the things.
Here is what the intake looks like now. This motor will look so good the day it gets i stalled. Then of course it will get years of oil leaks all over it and will look like every other Jeep. But you need to start clean, right?
I need to start doing this. If I took my parts to work my projects would get done alot faster. ?
Question. I am now wondering if I put the wrong dust shield on between the bellhousing and the transmission. The one I put on worked and the holes lined up. But I found another one in the parts pile this morning and I cannot recall which came drom the 4.0 and which came from the 4.2. And I am really thinking I put the one from the 4.2 on last weekend. Would it matter? I assume the hole for the starter should be in the same place.
Second question, I believe that the computer needs a pre-cat O2 sensor, correct? Can I have a bung welded into the exhaust manifold? Or does it need to be in the pipe after the manifold? My Sniper had it in the exhaust manifold, so I would think that would work, right?
Thanks. I remember from the sniper i stall that it needed to point as straight down as possible, so on the exhaust manifold that may be more difficult than the headers I used to run. But I will mock it up and see. I am not sure I want to run the post cat O2 sensor , u less I HAVE to.Yes, that sensor is the entirety of the A/F ratio feed to the ECU, to my understanding. The other O2 sensor after the cat is purely for emissions to check the performance of the cat.
The idea with the O2 sensor is to get all of the exhaust included so that the system isn't acting on just one cylinder, but the average of all six. So as long as you're after the collectors, you should be ok. Looking at the location of that sensor in the stock application should help with location. Just remember to put the sensor in so that the tip is pointing down as much as possible (so the tip doesn't collect condensation).
I am not sure I want to run the post cat O2 sensor , u less I HAVE to.
If you use the 4.0 flywheel, use the 4.0 starter. If you use the 4.2 flywheel, use the 4.2 starter.
My red Scrambler has a 4.0, but with 4.2 flywheel/clutch/starter/bellhousing.
I also used all 4.2 accessories/brackets on the front end.
It all works fine, but kind of crazy. Especially since I have a 4.0 transmission, the AX15 ?
Took a quick break from work to see about attaching the transfer case to the transmission. Something is not letting them mate. The outer diameter of the output shaft is about 2 and 1/8”. The inner diameter of the seal on the transmission is about the same. They should slight right together. I cannot tell if the seal is what is keeping it from going all of the way in or not, but it appears to leave a gap of about 3/8”.
Any ideas?
