Volvo D13 long crank when warm + coolant tank building pressure. Injector cups?

Hey everyone, running a 2018 Volvo VNL with a D13. Lately, it's been taking a long time to crank and start, especially after sitting for a bit when warm. I also noticed the coolant expansion tank is building a lot of pressure, and the coolant looks a bit darker than usual.

​Does this sound like failed copper injector sleeves leaking combustion gas into the fuel/coolant lines? For anyone who has done this job recently, did you go back with copper or switch to the stainless steel cups? Thanks!
