We only had to replace maybe 1/3 of the valves. I guess what matters is what type of chain failure happens.

In one case the chain broke and froze all the cams so only whatever valves were too far in at that point would be a problem and the engine killed so wouldn't keep spinning to cause more damage.


Yep it was a catastrophic failure. The PO said he drove for at least a tanks worth of fuel once he heard the noise. The chain eventually chewed up enough of the lower timing cover to completely come off the U guide and fall off the crank sprocket. It all back together now and running really strong though.
