The top of the cylinders are covered by the cylinder head The 'Outer Shim Type System' allows for the replacement of the shims without the need to remove the camshaft The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout.

Additionally, the 3S-GTE engines were based on the 3S-GE designs The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head. A single timing belt drives the intake and exhaust camshaft. 0 L The cylinder heads are made of aluminium alloy. The intake manifold has four independent ports and benefits from inertia build up to improve engine torque at low and medium speeds. The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron. All 3S-GE engines had a displacement of 2. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components.
