Oil Pan Gasket - Olds V8 330-455

The Oil Pan Gasket for Olds V8 330-455 by Milodon is an essential component for anyone maintaining or rebuilding a classic Oldsmobile big-block engine. This two-piece rubber gasket kit addresses one of the most common leak points in V8 powerplants—the oil pan seal. Whether you're restoring a muscle car, performing routine maintenance, or diagnosing persistent oil seepage, a quality replacement gasket is non-negotiable for keeping your engine bay clean and your oil system performing as designed.

Milodon's two-piece design distributes sealing pressure evenly across both sides of the pan mounting surface, reducing the risk of warping and resealing failure. The reusable rubber formulation withstands thermal cycling and modest oil temperatures without hardening or cracking—a critical advantage over single-use gaskets that degrade after one installation cycle. The 26-inch length and compact cross-section accommodate the full pan flange geometry of Oldsmobile's 330 and 455 cubic-inch V8 blocks, ensuring complete coverage and proper compression during torque-down. Compact packaging (6 x 0.5 x 26 inches, 0.42 lbs) makes this kit easy to stock and handle during engine work.

Technicians and engine builders targeting Oldsmobile muscle cars—4-4-2, Cutlass, Toronado, and full-size models from the 1960s through 1980s—will find this gasket indispensable for a leak-free, long-term seal. Installation requires basic pan removal and surface prep; old gasket material must be cleaned thoroughly to maximize sealing effectiveness. Proper torque sequence and even bolt tension are essential for optimal results. This reusable gasket design makes it cost-effective for both one-time repairs and professional shop use.
