I was hoping the oil change at its last service would help, but it hasn't.
How easy is it for someone to check the lifters and bearings? Is it a case of only knowing once they're all stripped out?
What are people's thoughts on switching away from Volvo's recommendation of 0W30 to 0W40?
I read on another forum that sometimes the lifters can just be sticky, and it's worth trying a decent oil additive like LiquiMoly first to see if that helps.

I was reading up a large suppliers site who described in detail all sorts of top end faults and for almost all faults they recommend flushing the engine oil as well as changing parts. Top end oiling problems cause so many faults!
I'm going to liquimoly flush mine first and go from there.
Agree a write up on this job would be great!
