Using a cylinder gauge, measure the cylinder bore diameter Thrust a t positions A, B and C in the thrust axial directions. STD mark "3" STD mark "2" STD mark "3" , I f the diameter is greater than maximum, rebore all four cylinders. I f necessary, replace the cylinder block.
The mark is stamped on the top of the piston. Distance: 2L-T Piston diameter: 3L - STD mark "1" See page EM c Subtract the piston diameter measurement from the cylinder bore diameter measurement. Standard oil clearance: 0. I f the oil clearance is greater than maximum, replace all four pistons and rebore all four cylinders.

This allows a proportional in- to the engine are either turbocharger type using crease in thefuel that can be burned and hence exhaust gas to turn the turbine or supercharger raises the potential power output. When the prescribed air pressure, the flow of exhaust gas turbine wheel revolves, the impeller wheel which is by-passes the turbine, controlling turbine wheel located on the same shaft also revolves, compres- revolutions and turbocharged air pressure.
This sing the intake air which has passed through the air by-pass valve which controls the quantity of ex- cleaner. When expelled from the compressor hous- haust gas flowing to the turbine is called the waste ing the compressed air i s supplied to the cylinders: gate valve. When the charged air pressure exceeds When the engine speed increases, the exhaust gas the prescribed pressure, the actuator operates, the volume increases and the turbine wheel revolutions waste gate valve opens and part of the exhaust gas increase approx.
This causes a drop in the turbocharged air pressure grows greater and engine turbine revolution rate and controls the charged air output increases. Idle the engine for 20 - seconds, depending on the severity of the driving con- dition.
Avoid sudden racing or acceleration immediately after starting a cold engine. I f the turbocharger is defective and must be replaced, first check for the cause of the defect in reference to the fol- lowing items and replace parts i f necessary: Engine oil level and quality Conditions under which the turbocharger was used Oil lines leading to the turbocharger No!
Do not drop it or bang it against any- thing or grasp it by easily-deformed parts, such as the actuator or rod, when moving it. Before removing the turbocharger, plug the intake and exhaust ports and oil inlet to prevent entry of dirt or other foreign material. I f replacing the turbocharger, check for accumulation of sludge particles in the oil pipes and, i f necessary, replace the oil pipes. Completely remove the gasket adhered to the lubrication oil pipe flange and turbocharger oil flange.
If replacing bolts or nuts, do so only with the specified new ones to guard against breakage or deformation. If replacing the turbocharger, put 20 cc 1. If overhauling or replacing the engine, cut the fuel supply after reassembly and crank the engine for 30 seconds to distribute oil throughout the engine. Allow the engine to idle for 60 seconds. I f the engine is running with the air cleaner, case cover and , hose removed, entry of foreign particles will damage the wheels which run at extremely high speed.

Thanks for valve clearances as is 1st check of valve clearances.. Oxygen controls the cancer. Contact As. Home Toyota Toyota 2L. Dear visitors, this site is not a trading platform, an official dealer or a spare parts supplier, so we do not have any price lists or spare parts catalogs.
We are an information portal and provide the technical specifications of gasoline and diesel engines. Pls I need more experience of how to converted diesel engine to petrol of hillux 2tr. Will the 2L-II directly replace a 22R motor in a toyota pickup without modifications? Does anyone have a bellhousing that can adapt the 2L to an AF transmission?
