SK991.2

Saw this thread looking to see if there was any trend in blown motors.. we have 2 GT4RS , both with less than break in miles, with engine failure due to LOSS of oil pressure.

Diminished value?? I couldn't get top dollar for my 991.1 GT3 because it didn't have a replacement motor as the original was running fine. Go figure!

You have two 4rs with minimal miles and both have blown motors?

There have been quite a few incidences of this now.

Oil Pump failure which leads to starvation and then kaboom. Not just isolated to 4RS, examples of 992 GT3/RS failures also.

I had the same issue about two weeks ago and started two threads to see what the experiences have been with any similar issues. I have a friend who was trained at the factory and he told me he has a friend that bought a 1200 mile 4RS from a California dealer and had the same oil pressure issue. This is all too coincidental with the factory warnings about the use of the C40 GT oil.
My oil was changed at the first yearly service in October of 2023 at about 2100 miles. I sent an oil sample to Blackstone for analysis. It came back clean except for a note about high iron and aluminum numbers but also said this was normal in the first oil change after break-in. I also insisted that the servicing dealer print the engine data report. That was clean also with no over revs. My oil pressure issue happened at about 2300 miles, 200 miles later!!
My GT4RS was flat bedded to a Northern NJ dealership who is still waiting for word from PAG as to when they will have a new engine. It looks like I am in a long wait. I have decided that I will contact PCNA if I do not hear anything in a reasonable amount of time. I have owned Porsches for 55 years and all this is not the "old Porsche AG".

Not so cut and dried. With the 991.1 GT3, the values rose with engine replacements (as it meant you had some improvements). And if you have higher miles, a zero-mile (identical) replacement would raise the value as well. In this case, I would say it would be close to no difference (to slightly less than original value). Porsche motors are easily changed and it's not a big deal.

ipse dixit

That's not really a fair comparison.

With the 991.1 GT3, a new engine (esp. a G engine) meant that supposedly it was an "improved" engine (over the E and F iterations) where the finger follower issue was remedied. In other words, with the 991.1 GT3, you're actually getting a different (improved?) engine.

Here, you're getting the same engine, just a new one. But it's still the same engine.

What's your production month? Dec 2023？I am afraid there are more similar cases coming.

I believe it was September 2022. I received it at the end of October.

Surprised to hear this. If it’s the same engine as the 993 gt3, I’m surprised we’re not hearing more of this issues on both the 4rs and gt3

I think you meant 992👍

As a guess how many of this engine type have been report here on RL?

Would be interested as well, sounds more common than I had originally thought.

Now we have two new similar cases from China, both cars were delivered in around May this year. Not oil pump problem. Dealer sent report and data to Germany and waiting for reply, asking for a new engine. The old engine is not disassembled yet, no one has an idea about what went wrong.

Care to disclose where your data is coming from?
