[QUOTE="Richard L, post: 939128, member: 52972"] Years ago (1960's and early 1970's), Ford had a very bad reputation for building their engines with only a few small oil drain back holes in the cylinder heads. At higher RMP's oil would get pumped up into the head and could not drain back to the oil pan fast enough. The oil pump could not pick up enough oil so the lifters and bearings would get starved for oil. Over time it was very common for the lifters to clatter on startup, the rocker covers to start to leak and valve seals to fail. Any sludge or coking of the oil would dramaticly accelerate the demise of the engine. Ford has resolved those issues, and I hope they have not gone back to those same old design problems in their newer engines? ...Rich [/QUOTE]
