Toyota Car Parts - 3S-GTE Engines

To adjust the valve clearance, adjust the shims above the valve lifters (shim over bucket system) Depending on where the engine was intended to be sold the exhaust turbine is either ceramic (JDM) or steel (USDM) The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps The third-generation engine uses the Toyota CT20b dual-entry turbo, and the fourth uses a proprietary CT20b turbocharger whose exhaust housing is actually cast into the cylinder exhaust manifold, rather than the normal practice of a separate exhaust housing after the cylinder exhaust manifold and it can only be used on the 4th Gen 3sgte head and not backwards compatible like the CT20b of the 3rd Gen 3sgte. The cam journals are lubricated by oiler port located in the middle of the camshaft Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation The third generation uses a normal 4-runner intake manifold Piston pins holding the pistons in place are locked by snap rings 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 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. 8:1 depending on generation 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 An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron The first two generations of 3S-GTE engines are equipped with TVIS. The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components. The turbochargers used in the 3S-GTE engines are Toyota designs. The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm. This prevents oil from being shifted away from the oil pump suction pipe
