Hard start when hot

Truck has been acting weird ever sense i installed bigger injectors.
It starts beautifully in the mornings, but if i drive it 30+ minutes turn the truck off and try to restart it takes a good 10 seconds for it to get going. When it cranks its the motor is firing but it takes a while for it to catch.

My guess is weak hpop sense the glow plugs aren't on when the truck is hot?
I should mention that the truck does have just under 400,000km and has a crazy amount of blow by coming out of both valve covers, so could it possibly be low compression?

What oil are you using? Is it due for a change?
It's definitely an ICP related issue. Could be the IPR, hpop, one injector just not quite seated right, or the oil itself

Rotella T, Just changed 700km's ago.
I do have an AE scanner, what kind of numbers should i be looking at?
I guess i could unplug the ICP connector while running, and if there is no change that would tell me that the sensor is bad?

To be clear, I don't think the ICP sensor is necessarily the issue. Just something to do with the high pressure oil system.
I'd imagine that it's just taking that whole 10seconds to build 500icp to start.
The oil is thinner when it's nice and hot, and is able to sneak through whatever tolerances easier.

It's a hard one to chase down.
About 6 weeks and many miles after I installed my injectors I had an oring blow out. It was installer error.
