FAQ

Q: How do I know if this valve guide fits my engine?
A: This part number 129101-16354 is specifically designed for the Yanmar 4TN100 diesel engine. Please check your engine’s model plate to confirm it is a 4TN100. If your engine is a different model (e.g., 4TNE98 or 4TNV98), this part will not fit.

Q: What are the signs of a worn valve guide?
A: Common symptoms include excessive blue smoke from the exhaust (indicating oil burning), poor engine idle, reduced compression, and valve train noise. Replacing the valve guide during a cylinder head rebuild is standard practice to prevent these issues.

Q: Is installation of this valve guide a simple replacement?
A: Installation requires removing the cylinder head, pressing out the old guide, and pressing in the new one. It often requires a valve guide driver tool and a reamer to ensure the correct stem-to-guide clearance. We recommend having the work performed by a qualified diesel mechanic to ensure proper fit and avoid valve stem binding.
