Case Savers, for 8mm Stud, 14mm Outer Thread, 8 Pieces

EMPI Case Savers for 8mm VW Engine Studs

Volkswagen Fitment Guide

These EMPI Case Savers are designed for use in VW Type 1 (Beetle, Karmann Ghia, Thing), Type 2 (Bus), and Type 3 (Squareback, Fastback) aircooled engines. They are the industry standard for converting or repairing 8mm head stud applications in magnesium or aluminum cases, providing a significantly stronger thread surface than the original engine casting.

Pro Tech Tips for Installation

Precision Machining is Mandatory: Installation of these case savers is not a simple DIY bolt-on process. Your engine case must be completely disassembled and professionally machined. The case needs to be bored and tapped specifically to accept the 14mm x 2.00 outer thread of the saver to ensure proper alignment and stud geometry.

Use High-Strength Thread Locker: Because case savers are intended to be a permanent modification to the engine block, apply a high-strength (typically Red) thread-locking compound to the outer 14mm threads before installation. This prevents the insert from backing out of the case when you are tightening or removing the cylinder head studs later.

Verify Flush Seating: After installation, ensure the top of the case saver sits perfectly flush or slightly sub-flush with the engine case deck surface. If the saver protrudes even slightly, it will prevent the cylinder from seating correctly against the case, leading to critical cooling leaks, oil leaks, and potential engine failure.
