Annnnnd, we're back. Massive Lifter Knock in my 5BW

[ATL_Bwing]

Well, here we are again. Had the oil changed in my 5BW on Friday at a Cadillac dealership (yes, same as previous dealership and the joyride issue. Lesson definitely learned). Drove the car Saturday, no issues. Drove the car again today, did a pre-trip inspection and checked the oil, clean and no issues. Drove ~25 miles to a meet up and when I got off the freeway I noticed a massive lifter tick. The car did not display any warning lights...check engine, low oil, none at all. But I immediately shut it down to be safe, waited an hour and checked the oil. Levels were fine so I fired it up, tick immediately returned and I noticed my oil pressure was spiking. I had it towed to Cadillac and am waiting for their diagnosis tomorrow AM. Inspected the undercarriage of the car when it was on the flatbed, and my garage when I got home, no signs of leaks or drips.

In doing my own research, all signs point to a mistake by the service team...either wrong oil weight, over-filled oil, or filter issue. Fingers crossed no long-term damage was done to the engine. What are your thoughts? And what should I be leery of when the dealer calls me tomorrow with their update?

Appreciate your thoughts and perspectives.

Check your invoice for the oil and filter part numbers that they used. You can google them to see if they used the correct ones.

Spiked oil pressure suggests a restriction somewhere--my guess is in the filter--which caused oil starvation.

Definitely sounds like they either double-gasketted the oil filter or used the wrong filter causing that pressure spike and starving your lifters.

My lifter tick just popped up out of nowhere one morning. No CEL, misfire or loss of performance. Took it to the dealership, and after the full teardown the lifter failure bent a rod and tanked the engine.

Engine was replaced with no issues from GM.

I just got my new 5 BW and reading this makes me sad. I came from a Genesis G70 and the one thing I really liked about service at Genesis was their all glass service center. I would sit and eyeball the tech the entire time doing my oil. Now I have to go back to some lube tech servicing my car in the back and then keeping my fingers crossed they did their job right. SMH.

Don’t worry… someone on this thread said it best — if there’s an issue, you’ll get a brand new engine with a new warranty period.

I’m on my 3rd V (2013, 2016, now 2023). My 2016 LT4 had 74000 miles on it when I traded it in. Not a single problem with the engine.

I’m staying with GM V8’s due to the long history of RELIABLE GM V8’s. Unfortunately COVID and supply chain appear to have messed it all up.

In summary, I was worried too, but in the small chance anything happens, you’ll get a free new engine and reset the clock.

Any update on this? Was it a blown motor due to manufacturer defect or dealer mess up?
