The 318 valve stem seals seem to wear out regularly and the oil
consumption goes up. Valve stem seals, the Carter BBD, and ballast
resistor were the only problems I had with the 318 in my '77 B200 van.
(Too frequent use of Heet kept eating up the seals in the BBD.)
Currently rebuilding a 318-3 from a '69 Dodge M300 motorhome chassis
.... brand-new heads with top quality aftermarket valve seals.
