Detailed Description

The MPR-304 push rod is part of Melling's engine valve train component lineup and is intended for standard replacement use where correct length, diameter, and tip style matter. This part measures 9.1 inches in length with a 0.343-inch diameter, 0.344-inch ball ends, and a drilled tube design. Melling recommends replacing push rods during service to maintain proper valve train geometry and performance. This part cross-references Monroe Shocks & Struts (e.g., 74-6304, PR-304) for the same application.

For Cadillac engine service, the MPR-304 supports the original-style push rod layout used in 1967 Cadillac Calais, Cadillac Commercial Chassis, Cadillac DeVille, Cadillac Eldorado, and Cadillac Fleetwood applications. The MPR-304 part number is also useful when matching interchange references during engine rebuild or maintenance work.

What It Helps Address

• Incorrect valve train geometry caused by worn or bent push rods.
• Noisy or inconsistent valvetrain operation from damaged components.
• Loss of proper lifter-to-rocker contact in serviceable engines.
• Replacement needs during top-end engine repair or rebuild work.

Installation Notes and Tips

Verify push rod length, diameter, and tip style before installation. Check for straightness and confirm the drilled design matches the engine's oiling requirements. Use the MPR-304 only in applications listed in the fitment data, and compare the original part number when servicing Cadillac engine components.
