I?s there oil coming out of the rocker shafts etc on the right bank when it is rattling The shaft gallery is connected to the lifter gallery only on the right bank with the feed coming from the left lifter gallery. Also it can take ages for the last lifters to quieten up.
I wouldn't be too worried about not being able to turn the pushrods with the engine stopped the lifters are a piston inside a sleeve with a spring under the piston to provide some static pressure when there is no oil pressure. It some cases it can be high enough to make turning the rods difficult, particularly if there is any residual oil pressure (which there will be on lifters in motion). A finger over the spark plug hole compression test will tell you if the valves are seating (if it blows your finger out they're seating - note its finger OVER the whole NOT in it!)

IT WOULD APPEAR THAT I HAVE A SOLUTION. I have been told by a person who is somewhat of a rover expert ,he has listened to the noise and identified it as two cylinder sleeves loose in the block.
Being a recond. motor he says that when things get hot and the pistons and rings expand as I have said after about 20 min. The drag on the bore
sleeve causes it to slide up & down between the head and the bottom of the bore. He says that this is rare but it is more common on older motors.
I would thank all who have contributed to my woes and I'll go out and shoot myself. (just kidding)

The moving liners only occur commonly in later 3.7" bore blocks where the std running temp was lifted by the factory, or they have seriously over heated - do some research on block cracks etc. Solution is 'top-hat' liners.
