Teething problems

Jul 19, 2011 update on ditchdigger's 1971 Fiat 850 Berlina

One week into the new motor the #4 exhaust valve kept going out of adjustment. By the time I ran out of threads on the adjuster I realized something was very, VERY wrong. The lifter and the lobe on the cam were gone.

Why? No idea, The other used cam and lifter are fine 2 weeks and an amazing amount of abuse later
