Replacement O-Rings, for Bolt On Valve Covers, 4 Pack

EMPI Replacement O-Rings for Bolt-On Valve Covers - 4 Pack

Product Overview

The EMPI Replacement O-Rings (Part #4527) are essential components for maintaining a leak-free seal on your aircooled VW engine. Designed specifically for use with EMPI bolt-on finned aluminum valve covers, these high-quality rubber seals ensure that oil stays inside your engine where it belongs. Over time, heat and pressure can cause original seals to harden or crack; this four-pack provides enough replacements for multiple maintenance cycles or both sides of your engine.

VW Vehicle Fitment

These O-rings are designed for VW Aircooled Type 1, Type 2, and Type 3 engines equipped with EMPI bolt-on style valve covers. This includes:

• Volkswagen Beetle (All Years)
• Volkswagen Karmann Ghia
• Volkswagen Bus and Transporter (Type 2)
• Volkswagen Type 3 (Squareback, Fastback, Notchback)
• Dune Buggies, Sand Rails, and Baja Bugs using Type 1 upright engines

Pro Tech Tips for Installation

Tip 1: Lubricate Before Installation. Before seating the O-ring into the valve cover bolt hole, apply a light coating of clean engine oil or assembly lube. This prevents the rubber from binding, pinching, or tearing as you tighten the mounting bolt, ensuring a uniform seal.

Tip 2: Avoid Over-Tightening. Aluminum bolt-on valve covers do not require extreme torque. Tighten the center bolt until the O-ring is firmly compressed. Over-tightening can crush the O-ring or even warp the aluminum cover, which leads to the very leaks you are trying to prevent.

Tip 3: Perform a Heat Cycle Check. After installing new seals and running the engine to operating temperature, let the engine cool down and check the bolts again. Thermal expansion can cause components to shift; a quick check ensures the O-rings have seated correctly and remain snug.
