Blackcoog, Have you fully read the thread entitled, "Correct Throttle Hang Mod"?? I have done my research. It names one thing in perticular that is bad to our Duratecs, but it also is questionable.
"If the engine's Plan B is removed, it resorts to Plan C: Sucking oil & crankcase vapors into the combustion chamber past the valves and rings in an effort to fill the cylinders on the intake stroke. Without an air source, a vacuum is created, and nature abhores a vacuum. So oil sucks in through the PCV valve, valve seals, and rings. The result is a fouled intake (when we already have a fouling problem to begin with), and worn rings, seals, and seats. "
That is a direct quote. Notice the words " with out an air source". That is assuming that there is no air source going to the intake when the throttle is let off when all this sucking of oil vapors and crap happens. But with the throttle hang mod done correctly there is an air source. It may be smaller or less than factory, but there is still air going in. Please go through the thread and read it from top to bottom. Pay careful attention to what DanG, PuckPuck, and FastCougar have to say. They are all reputable moderators and know what they are talking about. Do this and then if you want to come back on and tell me that I have mistaken, go right ahead.
Peace
