STC fitting

      Of all the issues that plague the 6.0L Power Stroke, which is its biggest problem?

 Torque-to-yield head bolts, EGR cooler, oil cooler, EGR valve, stuck turbo vanes, injector stiction, FICM failure, or high-pressure oil leaks? It seems that high-pressure oil leaks are never-ending for some 6.0L owners. Even once some have performed the STC (snap-to-connect) fitting update from Ford (on the high-pressure oil pump, '05-'07), they get a crank-no start and begin chasing dummy plug, injector, and even oil rail O-ring failures—none of which are easy fixes.

 In the January issue, we'll go beyond the "usual" head bolt, EGR, and oil cooler failures, and will be highlighting all the 6.0L's miscellaneous, yet common, problems.
