Hey Bill!
We did not get hit as hard as Texas, but it did effectively shut down virtually everything in the Memphis area.
UPS, USPS and FedEx stopped running for almost an entire week. Even Amazon was not delivering from their local warehouses!
It is a sunny 70 degrees today, so hopefully all that mess is behind us.
Sounds like y'all are having a great time out in AZ, enjoying the warm weather and some great roads.
With the oil filter relo and the oil cooler, there is No drop in oil pressure and No delay in pressure building. When I say no, I mean less than 1/2 of a PSI at the most, and less than 200 milliseconds difference in pressure building.
This is one of the first things we tested, extensively, when we were designing these parts.
Hopefully they checked the hoses for any kinks or pinches...highly unlikely they exist, but always a possibility, and that should be checked if it has not been.
No offense, especially if you like the guys at the shop, but it sounds like they're just guessing and replacing parts. Which may or may not be a bad thing if it is not costing you anything.
Whenever I am troubleshooting I always go by process of elimination, starting with the easiest and least expensive first.
Your Tri Glide is a '16, so the most common source of a clicking noise are the Rockers. Not hearing it, can't say for sure that is it. But it is far and away the most common. And it can start when new or after many miles. The solution is simple and inexpensive. Rocker Lockers, which you can see
HERE.
They have started down the lubrication path...first thing to check is the actual oil pressure, it is either good or not, and either comes up to pressure quickly (1-2 seconds) or not. If the pressure is good, (and it is not the rocker shafts) then it is time to listen with a stethoscope to see if the part of the engine making the clicking can be located. Then see if there is some blockage in the oil passageways feeding that area.
If there are no blockages (oh, and check to make sure the oil filter is not somehow the factor), then it may be time to start looking at hard parts, of which there are many that could cause a clicking noise.
That is where an Experienced Mechanic (not a Tech parts replacer) really comes into play, isolating the area and having the experience to know the difference between a rod knock, a partially collapsed lifter, a bad cam chest bearing etc.
But I would check the rockers first, there are 500 Twin Cams that click because of that for every one that clicks from something else.
Have fun out in AZ. Hope our paths cross again soon.
