The GM 6.2L L87 recall is pumas unam vs club américa more than just an oil change.
In this video, we’re doing a technical deep dive into the L87 oiling system to understand why these bearings mobland are failing. I broke out this old 4.8L crankshaft to give you a clear visual of the oil path; it helps explain that if debris is hiding out in the crank during manufacturing, it's already over.
We're looking past the "0W-40 band-aid" to see the mechanical reality of these failures and what the recall findings actually mean for owners.
Key Topics:
gunther • The Crankshaft Oiling Path.
• How manufacturing debris leads to instant bearing failure.
• The "Hydrodynamic Wedge" and why it fails in the L87.
