2.7T w/ 170K Miles...To Rebuild or Not?
 

Engine & Trans out of car for turbos, mounts, clutch, rear main seal, & trans seals. I'm wondering if now is the time to dig in deeper & replace rings, crank & rod bearings, & valve seals? Last compression test we did showed good levels on all cylinders, so it's not a necessity, although lots of miles on car.
Complete TB & waterpump changed at 140k, so will likely leave that be for now, as that seems an easy job compared to the engine pull.

Not upgrading anything just staying stock. This is not my toy, but is my son's daily driver, so I just want to keep it reliably running.

So any comments on if I should be going after engine internals at this time?

I think if it were me and I had no reason to open up the engine I would leave it, it is high mileage but treated right and maintained these engines can go a long time.
