Yes; I agree with your logic here. I can feel my motor go. It's limped 5-6 times in 10,000 miles with a replaced spark plug to which remedidated the issue but I can hear the car bog down some times but not often. I'm sure it's on its way. I will ring it out until it pops.

Car has just crossed 13,000 miles, with no track time and only 12-13 quarter mile runs. Drinks almost no oil, but it does smoke occasionally on startup. Very easy driving miles, as I almost always take the wife. And we both know how that ends up!
I think mine would be the test case for how much wear this engine takes from easy miles. Most of the time when i drive it for 2-3 hours i might jump on it a couple of times. This thing has been babied.

Seemed fine today, although power still seems a little less punchy. But the wife did say "oh ****" once or twice so it could be me. You know you guys will be the first to know if anything happens.

Just checked the replacement parts catalogue. Seems they changed the valvetrain parts two times:
- new heads, new valve springs, new camshafts starting from engine F 03048 (must have been in early 2015)
- new camshafts (intake and exhaust) starting from engine G 05373 (mid 2016?)

Yes, thats it. They introduced the new dlc coated camshafts with motor #05373 (they count the GT3/RS/R motors consecutively).
The parts are identical for MA175 (3.8) and MA176 (4.0) engines. The engines only differ in displacement (crankshaft, con-rods, pistons).
As we allready told some times before, the GT3 / RS / R motors are basically identical. The changes in running production were applied to MA175 and MA176.

Our PC does not even want to talk about any of this. But then we are banned from the racetrack on pain of cancellation of Motorplan in our country.

Mine is an F (MJ2015), produced in April 2015 and has the newer heads. From MJ2016/G the motor has an updated oil pump but thats not so important. The new dlc coated cams are used since mid 2016 from what we know.
The letters E/F/G/H refers only to the model year. The changes in the cylinder heads are not bound to model year but were done on the fly in spring 2015 and summer 2016.
You can find the motor number on the engine hood, on the sticker where you can also find the vin. (Sorry, I'm not a native english speaker).

So can you check that number 05373 to see if it is an "F"?

I would be really interested to know what your engine number is. Mine is the G model year, was built late in 2015 (like October or early November) and my number is just above 1000

Are you sure? Maybe you got the vin, not the motor number?
The motor numbers are sequential from E0000xxx1 to G05xxxx. They don't begin to count from zero every model year (otherwise there were more than 10.000 motors alive today 8-))).
(DLC cams since G05373. Your motor has the same head than mine, because its greater than F03048 (from Feb/Mar 2015) but below G05373 (from mid 2016))
