Toyota 3MZ-FE Engine Specifications
The Toyota 3MZ-FE is a 3.3 l (3,310 cc, 201.99 cubic
inches) V6, four-stroke cycle water-cooled naturally aspirated internal
combustion gasoline engine, manufactured by the Toyota Motor Corporation
since 2004.
The engine has 6 cylinders in a V arrangement at a bank angle of
60 deg. The 3MZ-FE engine features a lightweight aluminum block with a
four-bearings crankshaft and two aluminum heads with two camshafts
(DOHC) and four valves per cylinder (2 intake valves and 2 exhaust
valves).
The Toyota 3MZ-FE engine is equipped with SFI (Sequential Multiport Fuel
Injection) system, ETCS-i (Electronic Throttle Control
System-intelligent), DIS (Direct Ignition System) with individual coils
on each spark plug and VVTi (Variable Valve Timing) system for the
intake camshafts.
A 92.0 mm (3.62 in) cylinder bore and 83.0 mm (3.27 in) piston stroke
give the motor a total of 3,310 cc of displacement. Compression ratio
rating is 10.8:1.

The 3MZ-FE engine has an aluminum cylinder block in a V arrangement at a
bank angle of 60 deg.. From the front of the RH bank cylinders are numbered
1-3-5, and from the front of the LH bank cylinders are numbered 2-4-6.
This engine’s firing order is 1-2-3-4-5-6. The engine has press-fitted
cast-iron cylinder liners.
The crankshaft is supported by 4 bearings and integrated with 9 semi
counterweights for balance. Oil holes are placed in the center of the
crankshaft for supply oil to the connecting rods, bearings, pistons and
other components.
Pistons are made of high temperature-resistant aluminum alloy. Piston

| CYLINDER HEAD |
The cylinder head is made of aluminum alloy, with a cross-flow type
intake and exhaust layout and with pent-roof type combustion chambers.
The spark plugs are located in the center of the combustion chambers.
The exhaust camshafts are driven by a single timing belt, and a gear on
the exhaust camshaft engages with a gear on the intake camshaft to drive
it. The camshaft journal is supported at 5 places between the valve
lifters of each cylinder and on the front end of the cylinder head.
Exhaust and intake valves are equipped with irregular pitch springs made
of special valve spring carbon steel which are capable of following the
cam profile at all engine speeds. The intake valve diameter is 34.0 mm
(1.33 in) and the exhaust valve diameter is 27.3 mm (1.07 in).
Adjustment of the valve clearance is done by means of an outer shim type
system, in which valve adjusting shims are located above the valve
lifters. This permits replacement of the shims without removal of the
camshafts.

Valve clearance adjustment data
Calculate the thickness of new adjusting valve shim so valve clearance
comes within specified values.
R = Thickness of removed valve shim
N = Thickness of new valve shim
M = Measured valve clearance
Intake:
N = R + [M - 0.20 mm (0.008 in)]
Exhaust:
N = R + [M - 0.30 mm (0.012 in)]
Valve shims are available in 17 sizes to range from 2.50 mm (0.0984 in)
to 3.30 mm (0.1299 in), in steps of 0.05 mm (0.0020 in).
Example (exhaust valve):
R = 2.70 mm
M = 0.52 mm
N = 2.70 + (0.45 - 0.30) = 2.85 mm.
