It would be useful if people also included the build date of their car and that can help to potentially identify a batch of engines based on months rather than by year alone.

The Northstar engines had this problem a long time ago but remedied in 2000 by utilizing squeeze casting for their blocks.

Is there a way to identify build date and location??

Update infiniti said my oil test was clean which the dealer physically seen coolant and metal in the oil pan!

They are going to pressure test the car when it heats up to full temp to see if it's going into a cylinder.

Dealer still think they need to replace the engine so they jumpi g through hoops for me

Wow... that Copper is high, and Aluminum and Iron are higher than average.

Here's my Q's UOAs for comparison:

Your engine needs to be replaced. Otherwise, with the Copper as high as it is, which is plain bearing material, I see rod knock in your future.

According to infinti nothing is wrong. I argued about the bearing metal. They claim its normal.

Keep the OCI low (3k’ish) and do Blackstone oil analysis reports to show any patterns up/down to help calm nerves / raise alarm bells.

The oil only had a bit over 2k miles on it

So infiniti claims there's a turbo seal that's bad? They want to change the driver side turbo and they say that can leak coolant into the exhaust. Does coolant run through the turbos??? Anyone have a diagram they could find and share?

Also it was my engine coolant that is the is going somewhere not the heat exchanger.

I'm guessing you have an air-cooled engine oil cooler since you have a Luxe.

I thought only the sport versions had the air cooled.

Man thanks so much!! You're awesome! I have been searching the internet for hours! So apparently the HE tank just cools intake air?

I have alot to learn about this engine. Not a clue about the oil cooler. I haven't touched the car since I have had only about two months so far.

Dealer is still advocating for new engine.

He has a 2019 Q60. It's my understanding that all trims of the 2019 Q60 have air-cooled oil coolers, including the Luxe.
