How much does it cost to replace a variable valve timing actuator?

The average cost for variable valve timing actuator replacement is between $730 and $848. Labor costs are estimated between $453 and $571 while parts are priced at $277. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

What is replacing valve timing?

In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. Two-stroke engines use a power valve system to get similar results to VVT.

What does variable valve timing unit ( VVT ) do?

The variable valve timing unit (VVT) is used to advance or retard the valve timing independently of the camshafts. The VVT units use oil pressure to control their movement. Over time, the VVT units can leak, requiring replacement.

What happens when you remove the VVT unit?

You may need to counter-hold the VVT unit itself to prevent turning the whole camshaft. With the rotors removed, you can see the slots cut into the ends of the camshafts (green arrows). The locking tool is designed to fit into these slots and keep the camshafts locked at top dead center (TDC) on cylinder no. 1.

When to inspect the CVVT oil control valve?

CVVT OIL CONTROL VALVE INSPECTION DESCRIPTION: When diagnosing the Continuously Variable Valve Timing (CVVT) system for rough idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire- related trouble codes, and/or other related symptoms, it may be required to inspect the Oil Control Valve (OCV) for proper operation.

How to remove the VVT unit on a Volvo C30?

Use a T30 Torx driver to loosen and remove the two screws (green arrows) holding the rotors to the camshafts. You may need to counter-hold the VVT unit itself to prevent turning the whole camshaft. With the rotors removed, you can see the slots cut into the ends of the camshafts (green arrows).
