Description
This listing is for a remanufactured cylinder head compatible with the 4.0 L DOHC V6 1GR-FE engine used in Toyota vehicles such as the Tacoma and 4Runner. This head includes the secondary air injection provisions and is rebuilt to OEM-level quality — ideal for replacing a worn, cracked or warped head, or restoring your engine after a failure.
Rebuild Process & Quality Assurance
-
Complete disassembly and hot-tank cleaning to remove all old deposits and contaminants. After cleaning, the casting is pressure tested to confirm structural integrity and ensure there are no hidden cracks or leaks.
-
Valve stem seals replaced; any worn valve guides replaced as needed to restore correct sealing and valve alignment.
-
A precision multi-angle valve job is performed, followed by vacuum testing (or equivalent sealing test) to guarantee airtight sealing and proper compression across all cylinders.
-
Deck surface is milled using high-precision tooling for a smooth, factory-quality finish — essential for proper head-gasket sealing and longevity.
-
Final cleaning, inspection, measurement, and re-assembly are completed under strict quality control standards.
