only way to check the oil is to pull the rocker cover off - messy though.

No its not rockers, I checked all that, and when I switch the engine off you can hear it stop with a click,
It does it hot and cold, Oil pressure is heaps, no loss of pressure, Im afraid its a skirt.

what pistons do you have in it? Forged? Hypers?

Well if it isn't a lifter it'll be something expensive to fix. I'd be assuming all the tolerances were spot on (piston rings etc).

I hope it is something easy!

Paul check your extractor bolts they may be loose or you could even be missing 1 or 2

I had a Clevo that made that exact noise after a day at Eastern creek. Everyone said including myself thought it was a lifter but turned out to be a cracked piston skirt on a forged piston.

I think Matt could be bang on if so you will have pressure in the block pull the dip stick and you will know.

Im with you Mat! Cracked skirt!
I will pull it on Saturday and dump the 289 back in it!
Put it on the stand and pull it apart.

Man you are patient, by now I'd have used gun powder, probably on myself!
