Just put new valves in my (11) Subi. There was nothing wrong with the old valves (74,000 miles). Busted timing belt is what caused the valves to burn out.
Burn out? Since it is a non-interference engine when the timing belt went the valves were smashed and bent to hell when the piston reached top dead center. I just hope it didn't mess up the pistons. This is an example of the damage when driving at a low rpm for only a few seconds. Nothing like metal on metal slamming into one another a couple dozen times. I would honestly sell the thing asap and say the heads were just rebuilt...since they were.
Hammer, this is an issue for most Volvo too. I got mine changed early and a two year guarantee. I will probably do it again in 2 years even though it isn't due for another 75k miles just to be safe. Rather spend $700 in preventative maintenance to have the belt changed than thousands for motor rebuilds.
