https://www.m3post.com/forums/showpo...&postcount=967 - spun bearings, elevated pb on 2 reports! High copper on final one. Comments not shown for report prior to spun bearings. 54k miles.
To clarify, the report I got a few hundred miles before the spun bearings stated I have much more elevated levels of lead. Once the engine started making some ratcheting noise, I got another test that showed very high levels of copper.
The replacement engine had 25K miles (vehicle had 54K), I replaced with VAC extra clearance bearings before installation.
Here's the latest report attached from end of August - with an additional 47K miles.
Funny that they think Aluminum bearings are installed in the engine.
This is driving daily including the difficult Michigan weather, parked outside.
