Toyota Car Parts - 3S-GTE Engines

The cam journals are lubricated by oiler port located in the middle of the camshaft The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head Its cylinders are numbered 1-2-3-4, cylinder number 1 is beside the timing belt The third generation uses a normal 4-runner intake manifold Piston pins holding the pistons in place are locked by snap rings 5:1 or 8 Spark plugs are located in the middle of the combustion chambers Compression ring 1 and 2, prevents gas leakages from the combustion chamber while the oil ring works to clear oil off the cylinder walls, preventing any excessive oil from entering the combustion chamber The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. 8:1 depending on generation The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout. To adjust the valve clearance, adjust the shims above the valve lifters (shim over bucket system) On the first two generations the intake manifold has 8 independent ports and benefits from the inertia build up to improve engine torque at low and medium speeds The turbochargers used in the 3S-GTE engines are Toyota designs. A distributor based system is used to fire the cylinders in a 1-3-4-2 order. The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components. The 1st and 3rd Celica generation intake charge was cooled by a Water to Air intercooler while the 2nd, 3rd MR2, and 4th generation relied on an Air to Air system. At the bottom of the cylinder block is an oil pan which stores the oil The 3S-GTE is an in-line 4-cylinder 1998cc engine from Toyota, based on the 3S-GE with reduced compression ratio and addition of a turbocharger. An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves. A panel is used to ensure that there are sufficient oil available in the oil pan, as the oil moves around the reservoir during movement of the vehicle The first two generations of 3S-GTE engines are equipped with TVIS. Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation.
