That's my patented cam profile designed to guarantee that you won't be buying as much gas. The lifter roller was not seized but was a bit wobbley. Yes, Mobil One was involved. I'd changed out to conventional
oil, maybe 1000 miles ago. Hmmm, too late? New Lunati cam and lifters in the mail, as well as stainless steel roller rockers, since I've lost faith in aluminum rockers. (I keep thinking about how aluminum degrades with age). BTW, This was the same valve that wiped out an aluminum rocker, right after I'd bought the car. Parts are due in Tuesday or Wednesday so should be able to make the Coronado Trail run.
