Description
When your International Harvester tractor starts losing power, running rough, or burning oil, the culprit is often worn exhaust valves that aren’t sealing properly. These valves take a beating from the constant heat and combustion gases, and when they start leaking, your engine’s performance goes downhill fast. Fresh exhaust valves restore proper compression and get your tractor running like it should.
What You’re Getting
- Set of 4 exhaust valves – exactly what your 4-cylinder engine needs for a complete refresh
- TISCO quality construction that handles the heat and pressure of hard farm work
- Precise machining for proper seating and long-lasting performance
- Direct replacement that fits your existing valve guides and seats
Built for Real Farm Work
These valves are designed for International Harvester’s reliable 4-cylinder gas engines that power many of the workhorses still earning their keep on farms today. Whether your tractor’s pulling implements, running a PTO, or handling loader duties around the farmyard, these engines need valves that can handle the constant cycling and high temperatures of agricultural work.
Made to Last
TISCO builds these valves to handle the demands of farm life – temperature swings from cold morning starts to full-load field work under the summer sun. The hardened steel construction resists warping and burning, while the precision-ground sealing surfaces ensure proper compression for years to come.
Good to Know
Exhaust valve replacement requires removing the cylinder head, so it’s typically part of a larger engine overhaul. While you’re in there, check your valve guides and seats – worn guides will kill new valves quickly. Make sure to torque everything to spec and use a proper valve grinding compound if needed to ensure perfect seating.
