How long does the valve seal job last? Do the new seals last for the remaining life of the engine like other vehicles? What about the other associated gaskets, vanos seals, etc? After a valve seal job at ~80-100k miles, should we expect another round of upper engine seal/gasket replacement at 150k miles (the work that A B Able Truck recommends)?

I am wondering whether the valve seal replacement work (and all other associated gaskets, etc) improves the reliability/maintenance of the N62 engine to a level of low worry (aside from the usual cooling system woes). And if so, for how long? I know "low worry" is a relative term, but hopefully you get the point of the question.

Maybe long enough until the transmission fails?
