Hydraulic Lifters

[Power Jet]

Hey guys,

Have some noisy lifters at the moment and have been like it for a little while. I have tried different oils and what not to quiet them down with no luck. My question is are they easy to replace them for a DIY or what is the process involved

You need to remove the valve cover, turn the engine until the 2 dots on the Cam Phaser sprockets are visible, mark Cam Chain for both sprockets (it is critically important that Phasers are fitted back in EXACTLY the same spot), retract and secure the cam chain tensioner, then remove one of the Cam Phasers and both Cam Shafts, after which you can remove the rocker arms and get to the lifters, fitting is reverse of listed procedure.

Special tools needed are: Chain Tensioner retractor tool (although you can use a piece of bent wire) TORX socket for Cam Phaser, and Torque Wrench for re-tightening the Camshaft bridges (10Nm)

Extreme care has to be taken when unbolting the Camshafts, as they have to be undone very evenly to ensure you don't break the bridges holding the Cams in place, or bend the Camshafts, same applies for fitting them back after replacing the lifters.

Hope this helps
