Description

When your Oliver tractor starts missing or making that telltale valve tick, there’s a good chance one or more exhaust valves have had enough. These hard-working valves take the brunt of every combustion cycle, sealing tight thousands of times per minute while dealing with extreme heat and corrosive exhaust gases. This replacement exhaust valve gets your engine breathing properly again so you can get back to the work that pays the bills.

What You’re Getting

High-quality TISCO valve engineered to handle the heat and stress of exhaust duty
Precise dimensions ensure proper seating and compression for maximum power
Heat-treated stem and face materials resist warping and valve burning
Direct OEM replacement—no modifications needed for installation

Built for Real Farm Work

This valve fits Oliver tractors across their lineup, from utility models to larger row-crop machines. Whether you’re running a smaller Oliver for loader work and chores or one of the bigger models for field operations, proper valve sealing is critical for maintaining compression and keeping fuel costs reasonable.

Made to Last

Farm engines work hard, and exhaust valves take more punishment than any other engine component. This TISCO valve is built with materials specifically chosen to handle the constant heat cycling and corrosive exhaust environment. The hardened seat face maintains its seal even after thousands of hours, while the precision-ground stem ensures smooth operation in the valve guide.

Installation Notes

You’ll need basic valve job tools to install this properly—valve spring compressor, seat cutter or grinder, and a good torque wrench. Check valve-to-seat contact pattern and lap if necessary for a proper seal. Remember that exhaust valves run hotter than intake valves, so proper valve clearance adjustment is critical once everything’s back together.
