Toyota Car Parts - 3S-GTE Engines

The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron 8:1 depending on generation The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights The first two generations of 3S-GTE engines are equipped with TVIS 5:1 or 8 To adjust the valve clearance, adjust the shims above the valve lifters (shim over bucket system) The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout Piston pins holding the pistons in place are locked by snap rings The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm Various aftermarket solutions exist all of which require replacing the intake headers or manifold 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 Its cylinders are numbered 1-2-3-4, cylinder number 1 is beside the timing belt. This allows for the replacement of the shims without the need to remove the camshaft The third generation uses a normal 4-runner intake manifold A distributor based system is used to fire the cylinders in a 1-3-4-2 order. This prevents oil from being shifted away from the oil pump suction pipe A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps. The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. At the bottom of the cylinder block is an oil pan which stores the oil There are four generations of this engine, which started manufacture in 1986, and continues to the current day. The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head. An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves. The compression ration is 8. Spark plugs are located in the middle of the combustion chambers. The turbochargers used in the 3S-GTE engines are Toyota designs. It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina.
