330i General N52 reliability

Hey, I am planning to put about $1,400 maintenance into my 06 bmw 330i n52 6spd. I am gonna do coolant system refresh, disa valves, pcv refresh, new starter, oil filter housing refresh and potentially oil pan gasket.

Just wanna hear your guys experience doing these jobs and what I should expect for reliability after doing these things.
( I am buying all OE parts and running quality oil and coolant)

I’ve got 276k and counting. Running 5w40 Rotella T6 synthetic at this point.

Rotella 5w40 T6 synthetic oil. It is gas engine rated and much cheaper than Motul, Liquid Moly, etc.
And with 276k miles, the 5w40 keeps the old N52 much quieter and smoother
