Damn I got a pretty good oil leak from this ICP relocation kit. It appears to be leaking somewhere around the ICP sensor or the adapter fitting that mates the ICP sensor to the hose. I’m going to take it apart and use some thread sealer and PTFE tape. Hopefully that will plug it up.

It's typically at the ICP to adapter, using the bonded seal instead of the captured o-ring seal cavity that's OE. It's why I need to buy the port tool and make the adaptor work with the original design.

I got about 10 miles on the engine so far. I was able to get some nice load on it early on to aid in the ring seating. The engine seems to run smoother with this camshaft it’s hard to explain and it seems to also spool a little faster. I did not notice any piston slap or excessive noise. Sounds like it it did before just a little smoother. I’m sure new injector also help that.
My HPO system seems happy. Hot idle around 20-21% IPR I was at around 24 before. This 6.4 starter is nice. Engine fired off in about 1.5-2 seconds.

Charged up my system after vacuuming for 3-4 hours. No leaks detected. I added about 64-66 ounces of Freon spec is 4.25 The ambient weather was a little cooler so I couldn’t get a good heat load on the system. It was about 68-71f during my recharge.
Tomorrow during the day it should hit about 83 I’ll recheck my pressures. The high side seemed a little low to me but the air coming out the vents was cold. I’ll get some numbers tomorrow but I’d guess low-mid 40s on my discharge temps

Good to hear it wasn't that ring. Which would mean I don't need to port the fitting.
Another thing you could try if you have thread leaks is Loctite 567. I've used it on hydraulic fittings for decades with excellent results. It's rated as low strength, but it seems stronger than that.

Got her on the highway today. Put about 50 miles on it. Varying the rpm and load. Running good. I suspect the oil temperatures will drop a little bit once the engine break in is done. Running the standard delo Dino oil for the initial 1000 miles then will switch back over to a full synthetic. No complaints engine runs smooth. Hot starts in about 1.5-2 seconds. Hopefully all remains well.

Some observations from today. Truck is building boost much faster and overall I have gained some boost up top at WOT. I now seem to be able to hit 24-25 psi. Before 20-21 was all I could make WOT unloaded. The cam feels like it lost a small amount of off the throttle bottom end but picks right up at 1200 rpm and pulls smoother. It’s little less twitchy than it was before.

Well this sucks! My tried died out by my house about 2 miles down the road. I put 120 miles on it so far and it was going real good. It just flat out died while accelerating. The turbo barked and I said oh we blew a hose off. Nope. Oil level is good. My ICP is only going to 250 psi and my IPR maxes out 85 during cranking.
The high pressure oil system was mostly rebuilt minus the HPOP. New hoses, stand pipes, the flexible oil lines to the rails, oil rail nipple cup seals. Sucks!!! I don’t see any external oil leaks on the engine.
did my HPOP die?
did I develop a massive leak?
