One of my race shop techs went to work at Porsche
Over a few beverages he told me all 991.1 gt3 engines (including RS and R) have this problem and steer clear..and he knows his stuff
They cut the oil filter on every one that comes in, each one is a little worse each time
We used to coat the rod bearings in race motors with the same stuff. It lengthens the part life but it will eventually fail. Just a band aid
Porsche warranties the gt3 because they were forced to
Enjoy the car while under warranty..then punt it
I wouldn't own any 991.1 gt3 variant out of warranty..even RS or R
Local race shop had a guy buy a bubble wrapped .1rs a few months back..it Thru a rod at 900 miles on track. Porsche is being a ***** about warranty engine since it was not broke in to spec

Funny enough, I've read alot and people say that the '16 RS havent reported similar failures..but If i tend to agree with Izzone...

But these days i do not know if I want to own any modern car out of warranty. - just getting to expensive to fix them.I f I really like a car and can get an extended 2 year deal at a fair price- than I would extend and enjoy a few more years before trading out.

RS failures are rare because that engine does not rev to 9000 rpm!
big difference to what happens to an engine at 9000 vs 8500 rpm.
It looks like this 991 generation gt3 is going to go into history books as the most fragile gt car.

On the .2 motor they
Changed valve train to solid lifters to fix FF issue
Bottom end cross drilled the crank to fix bottom end oiling
It's not if a .1 motor fail, it's when

I am curious at what RPM range is the FF getting the least amount of oil lubrication.

Trakcar or Kobalt tracked 991.1 RS a lot without engine issues to my knowledge so far.

Wouldn't surprise me if it's at lower RPM's when the oil pressure is the least. Maybe when the cars are driven harder they survive better/longer because of higher pressure? (I did not stay at a Holiday Inn Express last night and neither am I an engineer, this is a complete guess...)

This actually makes sense. We didn't meet with PAG until August 2017, so the permanent fix wasn't in until after that, and there were engines in inventory to go through. So the 3rd engine you had replaced in June 2016 was prior to the new engine fixes. Now if the 4th engine goes, that could be a problem because it should have all the fixes in it.
Good luck!
