Toyota 3VZ-FE 3.0L Engine Specs, Problems, Reliability. Toyota began the production of 3.0 liter 3VZ-FE engine in 1987 as the new engine for Toyota 4Runner. This engine was set up in other off-road Toyota designs in the future. The engine is similar to its predecessor the 2VZ engine, but the more substantial displacement is not the one difference.
The cast iron cylinder block looks the same, but it is taller by 20 mm (the height is 223 mm). The angle in between cylinders in V-shape configuration of the block is 60 deg. Inside the block, there is new forged crankshaft with 9 counterweights and 82 mm stroke.
The early variation of this engine 3VZ-E has SOHC aluminum cylinder heads and original pistons. The compression ratio of these engines is just 9.0:1. The redeveloped version and more performance engine the 3VZ-FE was produced from 1992 to 1997. The 3VZ-FE got aluminum DOHC heads with the increased diameter of the intake valves to 34 mm from 33 mm. The engine doesn’t have hydraulic lifters. The shape of consumption valves likewise was changed. 27.3 mm is the diameter of the exhaust valves. There are numbers for changing valve spaces: 0.25-0.35 mm consumption, 0.15-0.25 mm exhaust.
3VZ camshaft specs: period – 230 consumption 230 exhaust, 12 deg overlap, 7.85 mm intake lift (or.31″), 7.6 mm exhaust lift (or.30″). Timing belt drives the consumption cameras. The exhaust webcam is driven by intake camshaft through equipment in the middle of the cylinder head. The engine has variable geometry intake manifold called ACIS by Toyota. The exhaust system likewise was tuned and optimized.
The engine was designed to be set up with 15 deg angle to utilize it in many applications. The producer slowly changed 3VZ-FE engine because 1994 by 1MZ-FE, but 3VZ got brand-new life as the 3.4 liter 5VZ-FE in 1995.

Toyota 3VZ-FE 3.0L Engine Problems and Reliability
Of all the engine has the issue with overheating. The reason can conceal in the bad head gasket. Likewise, the coolant fan doesn’t do its job as good as should. Attempt to keep the radiator tidy and the needed coolant level for this engine to prevent getting too hot in the future. The 3VZ has the concern with increased linking rod bearings wear and cylinder head cracks.
The engine life is about 180,000 miles (300,000 km). Increased oil intake or knocking sounds from cylinder block location can acknowledge a quickly death.
