Detailed Description

Victor Reinz 11-10348-01 is engineered for exhaust manifold sealing where heat cycling and flange movement can challenge gasket integrity. The fiber-and-metal construction is selected to handle the demanding environment at the exhaust port while maintaining a stable seal. Victor Reinz has long supplied manifold gaskets to original equipment manufacturers, and this part reflects that OE-oriented approach across many Buick, Chevrolet, Oldsmobile, and Pontiac applications.

Use this gasket set when servicing exhaust leaks on 1988-1995 Buick LeSabre, 1991-1995 Buick Park Avenue, 1990-1995 Buick Regal, 1988-1993 Buick Riviera, and related GM models listed in the fitment data. The part number 11-10348-01 is also a useful reference when matching replacement exhaust manifold gaskets for these vehicles.

What It Can Help Fix

• Exhaust leaks at the manifold-to-head sealing surface
• Ticking or puffing noises from a leaking manifold gasket
• Loss of exhaust sealing after heat cycling
• Flange sealing issues during manifold service
• Replacement needs on aging Buick, Oldsmobile, Pontiac, and Chevrolet exhaust systems

Installation Notes and Tips

Inspect the exhaust manifold and cylinder head sealing surfaces before installation. Remove carbon buildup, corrosion, and old gasket material so the new gasket can seat evenly. Verify bolt-hole alignment and fastener condition, and follow the vehicle service manual for torque sequence and tightening specifications. Check for exhaust leaks after startup and again after the engine reaches operating temperature.

Quality Assurance

Victor Reinz supplies exhaust manifold gaskets to original equipment vehicle manufacturers, and this part is built to meet OE specifications across a wide range of applications. The 11-10348-01 part number is backed by that OE-focused manufacturing heritage for service work on classic and later-model GM vehicles.
