It's not flapping more of moving sided to side on the top pulley. How expensive are the tappet to replace? Can I still drive it? Was worried it was bottom end /shells related

If it is a tappet (cam follower to be correct) then it depends on many factors just how long it will last. Noisy tappets in a high milage engine isn't really a major problem as it's simply attributed to engine wear. A single noisy tappet that starts suddenly is more of a concern and needs investigation. You can't normally damage a tappet on a diesel engine as it doesn't rev high enough, but it can be something like a valve spring has broken, but I'd expect to hear it all the time. I'm thinking that a piece of carbon deposit has got stuck causing it to leak down. This is allowing a slightly larger cam clearance than normal. This clearance closes once the oil pressure is restored.

7000 miles is still a long time since oil change , Most on here change there's every 6000 miles ( I know LR state 12000 but ? )
You could try an engine flush then change the oil & filter see if that helps .
Do you know what type & grade of oil was used at last service ?

I remember they used to go on the old ford xr2/3i all the time as well as the stem seals.....don't think it's an imminent repair needed as they jack up after a second or two....but I would look at changing them sooner rather than later.....I just wouldn't be reving the engine on start up until they get to correct pressure?
I would though do a oil and filter change with good quality oil as a matter of course.

Is that not the stuff that needs to be drained after half an hour?
