I was under the impression that the infamous 'tick' started with the elimination of the iron sleeves, but apparently not. Now, the 'tick' is not normal, in the sense that engines shouldn't do that noise. It's obviously a tolerance issue. But why doesn't Ford say what it is??? And more importantly, why it hasn't been fixed? Even if it's not detrimental to the engine, it's extremely annoying, and even embarrassing. I don't get that attitude. Having said that, I took the risk trading my like-new 2018 F-150 Platinum with the 3.5EB (that's when the V8s were having issues left and right), for a 2019 Bullitt with an August 2019 build date, to clear the tensioner TSB. It just turned 1K miles today, and so far engine sounds great. But hope it stays that way ?. Hey guys, on a similar note, do any of you know what the heck is the other infamous engine noise prevalent on these engines: The 2K-rpm rattle??? This one apparently all engines have it, but you have to turn stereo off and quiet the exhaust to hear it, so some folks say they don't. I was one of them until I did those 2 things, and BAM! The annoying noise as there. At least it's drowned with one or both of those 2 things turned on, so not a huge deal. But still want to know what it is. Some say cavitation from the engine-driven HPFP. Others that it's the cam phasers. Hopefully somebody has an answer ?. Thank you.

The D4 tranny is just about perfect for a street car, especially coupled to the 3.73 Torsen, which my Bullitt has. Track rations make no sense on a Mustang, at least up to PP1 IMO. Maybe PP2s and Shelbys. Glad Ford changed them for the better :). It makes the car great on trips, with a usable 5th.
