What's new

23' Lz0 - loud bang while driving and metallic chirping / sqeaking at ilde?

New motor was approved under warranty. They didnt explain the problem, just cylinder 1 spun a bearing and did catastrophic damage. With the front seal being done around 2k miles ago, my theory is this:

Rtv pushed into the pan. Was picked up by screen on pickup tube. Oil was restricted, volume was not the same, but not enough to throw low oil pressure code.

Motor went through a few heat cycles where the bearing(s) got hot.

When it finally let go, there as load or higher rpms that finally made the volume restriction become too much and the bearing finally let go.

Not sure what else it could be...have a hard time wanting to belive this thing just let go. I have 10/32nds left on the ORIGINAL DURATRACS. The original tires outlasted the motor...

Good luck guys.

It's possible. It's also possible that things weren't machined properly from the get go and took this long to cause catastrophic damage. Maybe whoever did your oil change didn't fill it properly as many dealers have done.

It's also possible that your new engine will go out soon too.
 

They have the mark up figured out.
They are trying to squeeze too much efficiency of these motors in my opinion. At some point, between efficiency, power, and reliability, one has to go.
Bingo! Your post sums it all up! Only thing you are missing is $100,000 price tag comment
