Product Information Cylinder Head
1. Product Overview
The Toyota 22R (carbureted) and 22RE (EFI) are part of the iconic R-series gasoline engines. These 2.4L SOHC inline-4 engines were built for durability, simplicity, and ease of maintenance, and are well-known across global markets for use in pickup trucks, SUVs, and utility vehicles.
The cylinder head is made of aluminum alloy, featuring 8 valves with mechanical rocker arms and camshaft driven by a timing chain. They are often rebuilt or replaced due to overheating, warping, or valve train wear.
