[quote=jeffrey;19891Do you run unleaded fuel? These valve trains were lubricated in part by Tetraethyl Lead, a gasoline additive (or survivor of Fractional Distillation).
And no longer readily available.

The absence of this can cause premature valve train wear in these engines.
"Premature" being a relative term in a 53 year old engine.

I've only had the car for about 3 months, so it hasn't been run much. I did put about a half a tank of unleaded in it, but then I put in some aftermarket lead substitute as well.
