Default XB Failed Cosumption Test

My 2010 XB just failed the oil consumption test. The dealer is ordering parts. They recommended that I do the following parts also at a lower hour labor rate since they will have the engine apart. I can do all or some of their recommended parts. Any thought on these?
Timing chain
timing chain tensioner
8 countershaft bearings
2 camshaft bearings
oil pump

Absolutely non of those should need replacing on your engine unless you are well over 150,000 or they have wear on them due to oil starvation. Did they inspect them and show you the wear or are they just recommending it? BTW the timing chains have no scheduled replacement mileage and should be good for the life of the car. What mileage do you have on the car?

Pretty sure the camshaft bearings are a matched set with the cylinder head - so they are not replaceable - without replacing the entire cylinder head.

My recommendation - PASS
