Internal Combustion Engine

Case Study # 218

1997 Corvette; 5.7 Liter Engine OHV V8. The equipment particle concetration (EPC) of 10,642 is much higher than expected; this is the FIRST time this equipment was tested and rated CRITICAL October, 2001.

Recommendation: Consider scheduling this equipment for maintenance action in the near future. Specifically abnormal medium alloy steel Severe Sliding wear indicating a wiped crankshaft journal bearing.

   

Analytical results show the presence of 330 micrometer (um) medium alloy steel Severe Sliding wear. Analysis also show the presence of 20um Copper Alloy (including Brass & Bronze) as well as 20um White Non-ferrous metal (Aluminum), which is of great concern. Test also show higher than expected concentration of Lubricant Degradation (Varnish & Lacquer) as well as Synthetic Fiber material. The fiber material appears to be from a blown oil filter. Testing also show a high concentration of Black Metal Oxides (Fe3O4). Black Metal Oxides form as the result of heat due to friction from either improper or inadequate lubrication. Use of a lubricant with too high of a viscosity is detrimental.

   

Upon opening of inspection  engine (V510588); the main crankshaft journal bearing was found to be wiped with significant striations.

Secondary Damage, was minimized. Repairs initiated & Downtime was minimized.
