Distributor Gasket

The ALLSTAR PERFORMANCE Distributor Base Gasket (ALL 87250) is a composite gasket engineered for Chevy V6 and V8 engines requiring precise sealing at the distributor mounting surface. This critical component prevents vacuum leaks and coolant seepage at the distributor base, maintaining proper ignition timing and engine reliability. Sold individually, this gasket is a direct replacement for original equipment and ensures OEM-specification fitment on compatible Chevrolet applications.

Composite gasket construction offers durability and stability across typical engine operating temperatures without the brittleness of older cork or the cost premium of multi-layer steel designs. The gasket's compact footprint (3.15 x 3.9 inches) and minimal thickness (0.55 inches) fit standard distributor bases on Chevy V6 and small-block V8 engines. Proper sealing at this junction prevents vacuum leaks that can cause rough idle, hesitation, and timing control issues—problems that degrade drivability and fuel economy if left unaddressed. Installation requires removal of the distributor cap and rotor, making this an ideal choice for routine maintenance or rebuilds where the original gasket shows compression set or leakage.

This gasket suits engine builders, restoration shops, and DIY mechanics performing distributor service or full ignition system overhauls on classic and vintage Chevy V6 and V8 platforms. Whether restoring a first-generation Camaro, street rod, or classic truck, this ALLSTAR PERFORMANCE component restores the seal integrity that original gaskets lose over decades of thermal cycling. Keeping a spare on hand prevents downtime when gasket failure is suspected during diagnostics.
