Summary Verdict
The 2000 Chevrolet P30 is a capable platform, but its age and commercial use mean certain components are prone to wear and failure. The gasoline Vortec V8 engines can suffer from intake manifold gasket leaks and, in some cases, cracked cylinder heads. The 6.5L diesel is more susceptible to cracked heads and injector pump issues. Transmissions, particularly the 4L80-E, can develop torque converter or solenoid problems. Suspension components like leaf springs and ball joints are common wear items. Electrical connections and alternators are also areas to monitor. While rust can be a concern, especially in certain climates, most issues are repairable with proper maintenance and timely intervention. Overall, with diligent upkeep, the P30 can remain a reliable work vehicle.
