I note on one of the camshaft sites that they say you can use Holden v8 lifters but must check the preload.
I assume from this that the length of the lifter may be a little shorter ( or longer) than a Rangie V8 one.
if so , and someone has not checked the preload you may not have enough, ie 20 thou. If that is the case you have to mill some material off the bases of the rocker pillars.
Its a bugger to do now, but if you want it quiet, you may have to strip down so that you can see the lifters and check the preload. look at the RPI site to see how.

I agree with PhilipA about the preload also did they have the heads off when the cam was done? If so did they use composite gaskets as this effects the required push rod length and as Philip said you may need to machine your rocker posts. Setting preload can be a bit tricky but worth the effort. Holden lifters are the only lifters I have ever had probs with and I would never use them again they bleed down to easily IMO the oiler hole should make no difference because of the solid pushrod but you preload must be right and a little more is better than a little less.
Good luck with it
Peter

Dont use holden lifters, I know they are cheaper but they just don't work in Rover engines.


As PhillipA says, preload IS IMPORTANT, check www.rpiengineering.co.uk for info on how to check and adjust.

You can and do use holden lifters in 4.4's, do not know about stock rangie motors.

thanks for all your help i will check out site to see what they say about liffters also ive noted that airflow and other screws are that had paint on them have been tampered with thrbody setting has been changed so might have to take it to someone who knows more than me to fix once liffters are sorted
cheers chris
