Intake/Exhaust Valves internal failure on 2004 Volvo XC70

Engine began running rough. Loss of power. Hesitating. Check engine light came on. Dealer says the Intake and Exhaust Valves burnt out, an internal failure. May also need a new cylinder head. Dealer says could cost $8,700. What gives? This was my 20 year investment! How is it the engine blew up/needs to be rebuilt? Anyone else experience this?

I think that engine uses valve buckets of varying thickness to adjust the valve clearances, if the same dealer has been servicing the car all the time ask them if the valves burned because the clearance was never checked or adjusted, or at what mileage Volvo recommend checking clearances? Ask if there was anything you could have done to prevent this or have they sen this before? Look on Volvo specif websites and see if any one has seen this problem.

They said there was nothing I did and nothing they could've foreseen. I will look on Volvo specific websites. Thank you for your reply. I have a big decision to make. Pay to fix it or get a new Volvo. Of course the dealer would love to sell me a new volvo.
