RE: Finally got my R/T
epegasus i think they mean the newer engines the 4.6 & 5.0 only not the older ones. There have been many documented failures in both engines one of them being the plastic manifold cracking causing other subsequent failures. Any engine can have a failure but i think reoccurring ones of the same type would throw up a red flag to potential buyers. As for the older fords I own a 1968 mercury with a 302 & it has been run hard without any issues.
