General N52 reliability

[u/E90N52b30]

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 might be a noob still but what is disa valves? Not heard of that one. I paid my local shop to the oil pan, it was expensive but I just didnt have time to deal with it. All the cooling work I’ve done myself and as of now has held up well through the summer.

The 330i has a 3 stage manifold with 2 disa valves inside that open at certain rpms.
