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.
