I have finally crossed the threshold into the P3's after learning of an 08 XC70 for sale with 150k that has timing chain noise. I picked it up today and it is a beautiful car, but does have a bit of a rattle that seems to come and go. Prior owner had two garages diagnose it as such, and bailed due to the cost.
Unfortunately I don't have any experience with the 3.2L engine so I am flying blind. There are mixed opinions as to whether crack it open, or just run it. Since it is due for serpentine belt, couplers, tensioners and a water pump anyway I intend to open up the cover and inspect the chain and guides.
I would welcome any insights from anyone who has tackled this, along with any advice on tools or other parts I should have on hand. It has been awhile since I was elbows deep in an unfamiliar motor but it was too beautiful of a car to pass on.
