Description

When your engine starts running rough, burning oil, or losing power, worn exhaust valves could be the culprit. These hardworking parts deal with the hottest, nastiest combustion gases every time your engine fires. When they start to leak or stick, you’ll notice it in everything from higher oil consumption to that telltale blue smoke on startup. This TISCO replacement valve gets your Case IH running clean and strong again.

What You’re Getting

Heat-treated construction that handles the extreme temperatures of diesel combustion
Precision-machined valve head and stem for proper sealing and smooth operation
Drop-in replacement designed to OEM specifications
Durable materials that resist warping and cracking under thermal stress

Built for Real Farm Work

This exhaust valve fits the CDC-B series diesel engines found in many Case IH tractors from the era. These non-emission 4-cylinder 3.9L and 6-cylinder engines were workhorses that powered everything from utility tractors to row-crop machines. Whether you’re running hay equipment, cultivating, or doing loader work, proper valve sealing keeps your engine running efficiently and prevents costly damage down the road.

Made to Last

Farm engines work hard in dusty, demanding conditions, and exhaust valves take the worst of it. This TISCO valve is built with materials that handle the constant heat cycling and corrosive exhaust gases without premature failure. The precision machining ensures proper valve guide fit and consistent sealing for thousands of hours of reliable operation.

Installation Notes

This is a straightforward replacement during engine overhaul or valve job work. Make sure to check valve guides and seats during installation – worn guides will cause premature valve failure. If you’re doing multiple cylinders, it’s smart to replace all exhaust valves at once to maintain even compression and performance across the engine.
