What Does a Main Girdle Saddle Plug Do?

The main girdle saddle plug is used in the crankshaft girdle to:

• Seal unused or open passages
• Maintain proper oil control
• Ensure structural integrity of the bottom end

In high-performance builds, even small components like this play a key role in long-term durability.

When Upgrading to Type S or S2000 Oil Pumps for Enhanced Oil Delivery, These Jets Might Need Attention.” “Even as certain oil jets are threaded into the crankshaft main girdle, others are merely pressed in and, when got rid of, expose an unthreaded hole. This product provides a solution for sealing off the non-threaded orifice.”

Why This Component Matters

In engine building, small parts can make a big difference. This plug helps:

• Prevent oil leaks
• Maintain internal engine pressure balance
• Ensure proper assembly of the crank girdle
• Improve long-term engine reliability

Even as certain oil jets are threaded into the crankshaft main girdle, others are merely pressed in and, when got rid of, expose an unthreaded hole. This product provides a solution for sealing off the non-threaded orifice.

Ideal For:

• Engine rebuilds
• High-performance K-series builds
• Turbocharged setups
• Track and race engines
• DIY and professional engine builders

Applications: All K20A K24A
On account of the extraordinary thread pitch of the fastener, the bolt used for securing the saddle plug is bigger and Might necessitate adjustments to the windage tray.

Installation Notes

• Installed within the crankshaft girdle assembly
• Ensure proper fitment and sealing during install
• Typically installed during engine teardown/rebuild
• Follow torque and assembly specs

Performance Benefits of the K series girdle plug

While small, this component contributes to:

• Improved oil system integrity
• Reduced risk of leaks
• Better overall engine reliability
• Proper bottom-end assembly

Frequently Asked Questions

Is this necessary for a rebuild?

Yes, replacing small sealing components is recommended during any engine rebuild.

Does this increase horsepower?

No, but it supports reliability and proper engine function.

Is installation difficult?

It requires engine disassembly, so it’s best suited for experienced builders.

Conclusion

The crankshaft main girdle saddle plug is a small but critical component for any K20 or K24 engine build. Designed for precision fit and durability, it ensures proper sealing and contributes to a reliable, long-lasting engine.
