What did you do to your TJ today?

I have been toying around with some intake ideas for a while. Back and forth with using the OEM, Windstar and aftermarket cold air. I ran across a free Banks intake today (broken housing) so I installed it and played around a little. Still not sure, but I could change so tubes, add a better filter and this is getting closer.
I have dipped the front in water more than once and filled the OEM filter housing. That's my drive to relocate this filter.
This position in the photo is directly under the hood vent.
Could possibly go a 1-2" shorter filter and tuck in more, but I think this would clear. I'll keep playing around.

It’s cool you got that vent there to try to take advantage of, although I wonder if you would capture engine bay heat escaping vs cool air entering with out some addition all shrouding…. Just a thought. Paper filter for better filtration but then back to shrouds to keep it dry from the rain… I am a sucker for open air filters just for the sound alone look forward to final rendition- zip ties are okay 😂
 
It's been a while since I last posted anything. Last month Ol Blue had a front brake decide to start dragging, so I decided it was time for a brake job and replaced all 4 calipers, pads and rotors along with the brake hoses. It actually went better than I thought it would.

Now that the brakes seem to be sorted out, the engine felt like the present was a good time start up with a new set of rattles and squeals on start up. It'd settle down as it warmed up, but something was definitely unhappy. Part of it sounded like the exhaust rattling, some kind of light squealing along with the usual valve ticking. That squealing had me concerned about the OPDA and an the one on the 4.0 was looking fairly ancient so I ordered a new Crown unit and figured should be a quick swapout. And then the trouble started. Seems that the holddown bolt was tightened by King Kong. Couldn't get a rachet or impact on it and my old distributor wrench wouldn't stay on the nut. I didn't have a 6 point box wrench, so I ordered a fancy one from Amazon. It came in the mail today, so first chance I got, I popped the hood and it worked like a charm. The OPDA came right out.

The old OPDA had this sticker on the backside of it facing the block. It doesn't say anything about Mopar on it, just LDI, Inc whoever they are.

Then it was time for Round 2. The darn sensor was glued into the OPDA housing and I couldn't get it to budge. I took it down the vise in the ship and was trying to gently tap it back and forth with a hammer with the occasional twist with channel locks and the darn sensor broke in two. So it looks like I get to see how long the Crown sensor will last while I try to find an OEM or suitable replacement. I ran out of time putting it back together so hopefully I'll be able to sneak out there and finish the job tomorrow.

I also found this sticker on the firewall above the control module that I'd never paid any attention before. Makes me wonder what kind of issues Ol Blue was having back when the original owner had it and it was "New Blue". That date on it is from 2005 and Ol Blue was built in Sep 2004.

I've owned it since 2018.

How did the gear on the OPDA look? Get a look down at the camshaft gear?

OEM is best as many find issues creep up with the Crown sensors. But you're doing what we'd all do - use what you have and start looking for a OEM in the interim.

The OPDA gear looked great as did what I could see of the cam gear.

Check your IAT’s with that setup. I think you will find it is not pulling in the cool air you think it is - especially when moving.

That LDI, Inc decal is the OEM OPDA. My ‘06 has the same decal on it.

I am not really aiming for cold air. I am aiming to stop taking in water when I dip the nose into water holes. I am sacrificing one thing for another. Water being the greater of the 2 evils.

But I will likely check IAT out of curiosity.

The actual choice in hood vent location came to me from reading the linked post.

You'll need some sort of shield to keep water from coming in via the vent (ie: rain, washing, or water washing over the hood.

Ya, I'm not 100% on placement. Ordered a few tubes and another filter to I will play with the angle a little. I am hopeful to move the filter from under the vent. I have had the hood vents on for 3 years now and I am not looking to move them, but I can add some sort of deflector should the filter end up under the hole. In the end it may not work. Just tossing around ideas.
 
Disassembled interior under-dash wire harness. Troubleshooting RHD HVAC blower fan. The fan is underhood, behind the battery on RHD jeep. An interesting note; figured out the jeep service manual schematic refers to the HVAC housing as a single component called "heater control." Also note the actual blower wiring is not shown. You get to sort that out using the circuit numbers. Handy since the blower feed (ground through control unit and resistors) changes color at C205 (lt. green) connector under dash.

Think about a cowl intake with an Windstar filter. Several threads here about it...

I have seen that and its in the wheel house. I just want to toss around a few other ideas before jumping into the cowling. I have tossed around a few ideas with the Windstar filter under the hood and I may try them out depending on how this goes.
