Toyota Car Parts - 3S-GE Engines

The intake manifold has four independent ports and benefits from inertia build up to improve engine torque at low and medium speeds At the bottom of the cylinder block is an oil pan which stores the oil A single timing belt drives the intake and exhaust camshaft Compression rings 1 and 2 prevent exhaust leakage from the combustion chamber while the oil ring works to clear oil off the cylinder walls, preventing excessive oil from entering the combustion chamber Built into the cylinder block are coolant channels, which cool the block which houses the pistons This is sometimes referred to as a 'non-interference' engine The spark plug is located in the center of the combustion chamber. To adjust the valve clearance, adjust the shims above the valve lifters This prevents oil from being shifted away from the oil pump suction pipe There are four generations of the 3S-GE, which were used in the Toyota Celica, MR2, Toyota Caldina, Toyota Altezza and Lexus IS200 The cylinder heads are made of aluminium alloy. The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head. A baffle is used to ensure that there is sufficient oil available in the oil pan, as the oil moves around the reservoir during movement of the vehicle An indentation is incorporated into the piston head to prevent the pistons from hitting the valves, should the timing belt break (this is not true of the 3S-GE BEAMS motor). The ignition order of the cylinders is in the 1-3-4-2 order. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components. The 'Outer Shim Type System' allows for the replacement of the shims without the need to remove the camshaft. Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt.
