Description

When your Case tractor starts showing blue smoke at startup or you notice the engine burning oil, worn valve guides are often the culprit. These little bronze sleeves keep your valves moving straight and true, but after thousands of hours of heat and wear, they develop play that lets oil seep into the combustion chamber. Fresh guides restore proper valve operation and get your engine running clean again.

What You’re Getting

Complete set of 8 guides—enough for both intake and exhaust valves on your 4-cylinder engine
Quality aftermarket construction that matches original specifications
Precision-machined bronze material that handles heat and wear like the factory parts
Direct replacement guides that press in without machine work in most cases
TISCO brand quality you can count on for reliable performance

Built for Real Farm Work

This guide set fits the 124 cubic inch, 126 cubic inch, and G148 gas engines found in various Case tractors from the era. These were solid, dependable powerplants that ran implements, loaders, and PTOs day after day. Whether you’re restoring a vintage machine or keeping a working tractor in service, these guides help maintain the engine’s integrity.

Made to Last

Valve guides take a beating from constant heat cycling and the friction of valves sliding up and down thousands of times per minute. These aftermarket guides use quality bronze alloy that conducts heat well and resists galling, giving you the durability you need for long service life.

Installation Notes

Most experienced mechanics can press these guides in with the right tools, though some engines may need light honing for proper valve stem clearance. If you’re doing a complete valve job, now’s the time to check valve seats and replace springs while everything’s apart. A good machine shop can handle the installation if you don’t have the tools.
