WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
Inspect the 5 crankshaft bearing journals (1) and 4 connecting rod bearing journals (2) for wear:
- Grooves or scoring
- Scratches
- Pitting or imbedded bearing material
Inspect crankshaft bearings for craters or pockets. Flattened sections on the bearing halves also indicate fatigue.
Inspect the crankshaft bearings for excessive scoring or discoloration.
- Inspect the crankshaft bearings for dirt or debris imbedded into the bearing material.
- NOTE:
If the lower half of the bearing is worn or damaged, both upper and lower halves should be replaced.
Generally, if the lower half is suitable for use, the upper half should also be suitable for use.
Inspect the crankshaft bearings for improper seating indicated by bright, polished sections of the bearing.
