Head tightening procedure and torque specs: ![]() The stock size of fuel injectors is 276 cm 2 per minute. The intake duration is 226° and the exhaust duration is 226°. The intake camshafts are driven by a belt and the exhaust camshafts are driven by gears off the intake camshafts. The 5MZ-FE engine has double overhead camshafts DOHC design with four valves per cylinder (two intake and two exhaust valves). The cylinder head is made of aluminum alloy. Main bearing cap bolts tightening procedure and torque specs:Īfter securing bearing cap bolts, make sure crankshaft turns smoothly by hand. Number of piston rings (compression / oil): The cylinder bore is 93.5 mm (3.68 in) and the piston stroke is 82.0 mm (3.23 in). Each piston is equipped with two compressions and one oil control rings. The engine used forged, sintered connecting rods and aluminum pistons with full-floating type piston pins. Crankshaft main journal diameter is 64.000 mm (2.52 in) and crankpin diameter is 55.000 mm (2.16 in) ![]() ![]() The crankshaft is integrated with 5 counterbalance weights, for the LandCruiser Prado (90-Series) the crankshaft has nine counterbalance weights and a dual-mode damper. The 5VZ-FE engine has a cast-iron crankshaft. The crankshaft is supported by 4 bearings. This engine’s firing order is 1–2–3–4–5–6. The 5VZ-FE engine has deep-skirt cast-iron cylinder block in a V arrangement at a bank angle of 60°.
