Rod Knock at 4K miles.

[mjk1897]

Just passed 4k miles on my 23 ST a few days ago and started hearing a tapping/knocking when coming off throttle, started it the next morning and heard a consistent knock from the bottom end. Had it towed to the dealer and they told me it needs a new long block assembly and both turbos replaced (thankfully under warranty) and I was wondering if anyone had anything similar?

Dang I hate to hear that. What is the build date on your 23?
Mine is 11/23. I hope I don’t run into an engine issue.

It is very very uncommon for the actual engine to have problems on our cars. There was just a recall for bad valves on some of our cars so that could be it, very uncommon problem though.

I wish it was a valve issue, might get my car back sooner. according to the dealer both the oil and filter were full of bearing material. apparently after the engine is removed the long block is being sent back for failure analysis. the dealer said they hadn't encountered anything like this with one of the 3.0 engines before but I just wanted to see if they were being honest or trying to make it seem like a fluke. but everything else I've seen makes it seem like it really is a fluke.

The build date is on the door jamb sticker too.

Jut got an update from the dealer, when they drained the oil there was less than 2qts in the pan. the tech I talked to said they did not find any evidence of any oil leaks so its most likely an oil consumption issue caused either by defective rings or turbo oil seals. Oil consumption leads to low oil, low oil leads to low oil pressure, leads to a spun bearing.

I've seen so many post about people having issues with low oil and no warning! I'm checking my oil level every time if fill up now just to be safe!

Thanks for the update. When was the last time you checked your oil level?
Also build date on your ST.

I checked the oil at about 2k miles before a road trip and the level was right in the center of the range. didn't check it again after that.

Sounds plausible. Turbo oil seals are known to leak but have the telltail white smoke on startup.
