Hello the car in question is a 09 6.0 hybrid. The oil pressure at regular driving is around 60 and does fluctuate up and DC own depending on the driving but just casual cruising is always at the 60ish mark. It also sometimes makes a very hard to describe almost metalic grind to a stop when it turns off (the sound seemed to come from the intake manifold throttle body area when I put my ear to it), I use to hear what I'm assuming to be the lifters when it would first start, the rpms would also climb sometimes when driving so I replaced the TB last night, and have also replaced thr driver valve cover because it was burning oil fast and there was a PSA on the fix. Idk if all these could be related or not, we use 5w-30 in it. I also posted in the regular drivetrain. Sorry if double isnt aloud but with different oil line routing I didn't know if it could be hybrid specific
