There's another thread here or in another forum (I think it was here due to Sean's aircraft background) where I talked about installing a pre-start "priming" oil pump as aircraft engines do, pulling the oil from either the drain plug location or putting a through-hole in the oil pan sump, then using this port to pre-oil. I almost did that but I don't plan on keeping this truck so long to make it worth the cost. A CA or southern truck, it might be a consideration, You can adapt an oil pump that is used for differential oil cooling to a heat exchanger that is used in the racing industry.
I think that would be awesome, have it set up so it primes with the key forward for ten seconds or so then crank.
There are a couple of ways of doing it, with a pump from the sump or using an accumulator to store pressurized oil until the next start. With our engines generating about 70psi on the first cold start, the accumulator would charge up very well and be ready for the next start. Hot restarts and running the pressure would be lower, running getting into the 45-50psi range. But either is doable.
This could have been a consideration if you were planning on long years, long miles of service, 300k miles or more. It appears the cams and lifters can be the weak links at about 275k depending on how you deal with oil integrity. The back galleries are the last to get full volume and pressure, and although any, any lobes can have issues, there is an uptick or at least the belief the rear four have the worst record.
I'm still on the fence if I want to do this just to show it.
Back in the day when I hotrodded Buick and AMC Javelins and AMX we used to run a oil line inside the lifter galley from the front to back of the cam.to aid in oil getting to the back lifters. Might be a good for thought on the 6.0 but I never thought of it till now.

You could tap into the rear oil galleys and hard line it around to the front of the engine. This damn thing has so many extra hoses now it looks like a bowl of spaghetti on top of the engine.
I think just using good oil is the simplest method and would have a good effect. Along with that, understanding the effects a bad oil cooler has on oil integrity and with the fuel dilution we have with idling.
It's not conclusive that the back lobes/lifters have the highest rate.
I’m waiting for 1990 F-350 to pop up on my thread and start talking trash and telling us we do everything the hard way, 6.0’s are junk and we are idiots for not taking our trucks to a Ford dealership for work.
It’s a M14x1.5 thread and you need a 3/4” or 19mm socket to remove it. I bought an aluminum fitting with a 3/8” barb so I can slip a piece of power steering hose on it. After priming I put the test port fitting back in. Of course they couldn’t have used a standard quick release fitting, it’s some special fitting that only God and Ford techs have access to.
