Not all V8 owners have it easy.
- One of my cars runs a much modified 4.4 engine and it runs Roller Rockers but I have stuck with the Hydraulic cam so the set up of the Roller rockers is also time comsuming and knuckle busting.
- I'm sure that Mick Lecoq and Warrewyk Willams will agree that this is one bit of maintenance that we would rather forget as we run this idea on our engines.
- From my experience its best to stick with a mechanical cam and put up with the rackett from under the bonnet with the rollers or don't run them at all if using a hydraulic set up.
- These arent set up by cyl firing order ie 18436572 but valve timing sequence of 1&6 at TDC onwards to the last cyls 2 and 3. I have tried different clearnaces but have ended up with no clearnace, but the pushrod being able to be turn around, and the thing still is about as load as an XU1 holden with a solid race cam.
- One day I will try some adjustable pushrods as they might be a doodles too short but only if over a long period of time affects the burning out of a valve etc.
- However when set up and quiet the low down torque of these big valve heads and roller rockers , makes the engine extremely flexible ie 3rd gear from 300 rpm up up a steep slope with out protest from the driveline.
- So you see not everbody has it easy when it comes to Leylands!

- Take the balancer off and mark it in 90 degree increments from TDCin
- a rotary table and milling machine.
- Rock CYL6 or if you are lazy get the dist rotor pointing to CYL1 @tdc.
- Set CYL1 tappet, turn 90 degrees set CYL 8, turn 90 degrees Set CYL4
- Easy when you know how.
