FAQ
Q: How do I confirm this valve guide fits my 4Y engine? A: Verify the part number stamped on your old valve guide. It should read 11122-71020 or 11126-71020. If you are unsure, measure the outer diameter and length of your original guide and compare it to the OEM size specifications for the 4Y diesel engine.
Q: What is the recommended installation procedure for this valve guide? A: Installation should be performed by a qualified diesel mechanic. The cylinder head must be thoroughly cleaned. The old guide is typically pressed out, and the new guide is pressed in to the correct height (protrusion) as specified in the Toyota 4Y service manual. Always ream the guide to the correct valve stem clearance after installation.
Q: What is the typical lead time for international orders? A: For stock items like this valve guide, orders are typically processed within 1-3 business days.
