Camshaft, Engine: Description
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Pentastar engine uses a Dual Over Head Camshaft (DOHC) configuration.
- The camshafts are a nodular cast iron design.
- Each camshaft has a pressed on magnetic timing wheel that is magnetically encoded.
- The two Camshaft Position (CMP) sensors are located between the timing wheels.
- Attached to the rear of the right exhaust camshaft is a centrifuge which is part of the crankcase ventilation system.
The centrifuge is used to separate oil droplets from the crankcase gases before they enter the PCV valve. Four bearing journals are machined into the camshaft. Camshaft end play is controlled by two thrust walls that border the nose piece journal.
