When your tractor starts burning oil or losing power, worn valve guides are often the culprit. These little components have a big job—they keep your intake and exhaust valves aligned and sealed tight so your engine runs the way it should. When they wear out, you’ll notice blue smoke at startup, oil consumption, and that annoying ticking sound that says your engine isn’t happy.
What You’re Getting
- Precision-machined guide that keeps valves properly aligned for optimal sealing
- Durable construction designed to handle the heat and stress of engine operation
- Direct replacement part that fits like the original—no modifications needed
- Quality materials that resist wear and provide long service life
Built for Real Farm Work
This valve guide is engineered for International Harvester engines that power everything from utility tractors to row-crop machines. Whether you’re running a Farmall doing hay work or a bigger tractor pulling implements through tough ground, proper valve guide fit is critical for maintaining compression and keeping oil where it belongs.
Made to Last
TISCO builds these guides to handle the demanding conditions inside your engine. The materials are chosen to resist wear from constant valve movement while standing up to combustion heat and pressure cycles that would destroy inferior parts.
Installation Notes
These guides require proper installation with the right tools—you’ll need a valve guide driver and should check valve stem clearances after installation. If you’re rebuilding the whole top end, it’s smart to replace all the guides at once. A machine shop can handle the installation if you don’t have the specialized tools.
