20v 4age Blacktop – VVT pulley + Seal

Description

20v 4age Blacktop – VVT pulley + Seal

This listing is for a new VVT pulley as well as the O-ring seal that fits between the pulleys rear cavity and the end of the intake camshaft.

It is common for the VVT pulleys on 20V engines to have completely failed or on the way out due to age and use. Sometimes it will be known with a loud ticking noise, but other times the only result is a loss of mid range power.

To test if the pulley is still healthy, the VVT solenoid can be unplugged without any risk of damage. This is located on the side of the cylinder head in front (left) of the header flange. When the engine is used without the VVT solenoid engaging there should be a considerable loss of mid range power. If there isn’t much change then the VVT pulley should be changed.
