I grew up in Los Angeles, and for many years the L.A. Times ran V-6 GMC Steel Tilts on LP. I wonder if that's the newspaper that had the issues! Von's Grocery also ran V-6 H7500 series tractors on LP. I have a lot of experience with CNG conversions on modern engines and not much is needed beyond hard valves and seats, as CNG is a 'dry' fuel. Never had any issues with the V-6's PCV system, though on light trucks there are only 2 valves. Never had a valve spring issues either, I wonder if the newspaper in question was trying to use old worn out valve springs on their rebuilds. Interesting article, thanks for posting!
