Hi everyone, so while doing my last oil change I noticed what looked like the "glitter of death" in my oil. So I decided to investigate and removed my oil pan. This is what I found.
Obviously bearing material so I started pulling the rod caps.
Starting with #3:
#2:
#1:
And #4:
None of them look too great but definitely not the culprit for the metal I found. More likely just suffered oil contamination as a byproduct of the metal circulating around.
Here's the main caps staring with the girdle farthest from the timing belt side:
Center main cap:
This thing is HAMMERED. And obviously the one that failed.
Girdle closest to timing belt:
None of what I find makes me very happy, but onward and upward. Looks like its time for a rebuild. I guess my question is what is the most probable cause of main bearing failure? Oil starvation? Oil contamination? Fuel wash? This motor has just over 100k on it and was stock for almost all of that. Basically I don't want to spend the money to do a rebuild only to have the same issues occur. Any input would be greatly appreciated.
