Case Study # 88 |
|
1994 Pontiac Grand Prix 3.1
Liter V-6 Engine. Although the
equipment particle concetration (EPC) of 5,020 is within acceptable
limits; this is the FIRST time this equipment was
tested and rated
CRITICAL September, 1999.
Recommendation: Consider scheduling this equipment for
maintenance action. Specifically white non-ferrous metal Severe Sliding wear indicating
incipient piston & cylinder failure mode. |

Analytical results show the
presence of 60 micrometer (um) non-ferrous metal particles. These
large non-ferrous metal particles appear to be debris from the piston.
This whit non-ferrous metal is most likely Aluminum.
Additionally, this large debris is of sufficient size to cause a metal
to metal interference with close tolerance and clearance components.
Analysis shows the generation of 35um Rolling Contact (bearing) wear.
This Rolling Contact wear is composed of a medium alloy steel. Testing
also show the presence of 20um white non-ferrous metal wear. The size,
shape and composition of these particles are of great concern. |

Upon opening of inspection engine; the
two-(2) pistons were found with severe striations.
Secondary Damage, was minimized. Repairs were effected in a timely
