Exhaust Camshaft Note (For Cross-Referencing)

Letter Designation: Bank / Cylinder Head Side

• R = Right-Hand Bank (Bank 1 / Passenger Side on LHD vehicles).

Number Designation: Valve Location / Function

On Toyota V8 valvetrains, the numbers correspond to position or valve type relative to the primary drive gear:

• R1 = Right Intake Camshaft (matches part number 13501-50040 / 13501-50030).

• L3 = Left Exhaust Camshaft (or Left Intake, depending on the specific engine revision casting layout; typically 1 indicates Intake and 3 indicates Exhaust secondary drive gear pairing).

The top camshaft (R1 - Intake) is slightly taller in overall lobe height and maximum valve lift than the bottom camshaft (L3 - Exhaust).

Why the Intake Lobe (R1) is Taller:

1. Higher Valve Lift: On non-turbo engines like the 1UZ-FE and 3UZ-FE, Toyota designs the Intake valves to open wider (higher lift) to allow as much fresh air and fuel mixture into the cylinders as possible.

2. Exhaust Lift: The exhaust side uses a slightly lower lobe height because exhaust gases are expelled under high cylinder pressure when the piston rises, requiring less valve lift to achieve clean scavenging.

Visual Identification Tip

• R1 (Top - Intake Cam): Noticeable by its broader drive gear ring on the shaft (which mates to the primary gear / timing belt gear) and its taller, slightly wider lobe profile.
