gunsaholic,
It's my understanding that the manufacturers changed to hardened steel valves and seats after they switched to unleaded gas. My only question is, why didn't the cheap SOBs do it sooner. I recently sold a 97 Dodge Caravan with 287,000 miles on it and it never needed a valve job. A far cry from the crap (I mean cars) Detroit used to build.
