Description

When your Case or Case IH is starting hard, running rough, or burning oil, worn valve guides might be the culprit. These little but crucial parts keep your intake and exhaust valves aligned and sealed properly so your engine can breathe the way it’s supposed to. If the guides are worn out, valves wobble around and let oil slip past where it shouldn’t go—problems that’ll hurt your power and cost you fuel.

Precision-machined guides that keep valves properly aligned for smooth operation
Durable construction that handles the heat and pressure of diesel engine operation
Direct replacement for factory parts—no modifications or special tools needed
Sold individually so you can replace just what’s needed or do a complete overhaul

Built for Real Farm Work

These valve guides fit the CDC-B series non-emission diesel engines that power many Case and Case IH tractors. Whether you’re running a 4-cylinder 3.9L in a utility tractor or the 6-cylinder version in a bigger row-crop machine, these engines see plenty of hours pulling implements, running hydraulics, and handling heavy loads around the farm.

Made to Last

TISCO has a reputation for making aftermarket parts that hold up to farm conditions, and these valve guides are no exception. They’re manufactured to handle the constant heat cycles and combustion pressures your diesel engine dishes out, season after season.

Good to Know

Installing valve guides is precision work that usually requires machine shop equipment to press them in properly. Most folks take their head to a shop for this job since proper guide installation is critical for good valve sealing and long engine life. The 4-cylinder engines use 8 guides total, while the 6-cylinder engines need 12.
