of course i would be doing a full filter and fluid service if i kept it but i wasnt about to do that in the p.o,s driveway before i bought it!

so lets assume for the moment it could be this tensioner shoe snap ring issue or pump related.

is it an easy and low cost job to replace these parts even if i get used items from somewhere?

is it safe to carry out a c.r test before i even look at this oil issue?

as i said there is a similar post on here but it went dead and no explanation was found

thanks again

To answer your question, if it is related to the oil pump, you need to remove the upper oil pan to replace it and the chain, tensioner, etc. The engine will need to be removed for that kind of job.

Typically, a tinking sound while running the car can be related to worn and missing shift lever bushings. Check them and see.

As a start, do some of the other tests these fellas have suggested. If you have negative results with them, drop the oil pan and check the oil pickup; it might be clogged with something.

A compression test is a moot point without proper oil pressure. You probably won't damage the engine by cranking it with the starter, though.
