Air Filter, debris ruining the bores.
depends how bad the rings are, sometimes oil will always be in the cylinder causing a good reading.

ahh, I haven't no.

I did do a compression test with putting a bit of oil in the cylinder and it didn't really rise much at all (around 5psi)

What do you mean by loose filter linkage?

I wondered that also. Perhaps liirge meant "leakage" not linkage?

My take is the same as those above who suggested bad rings. A leak down test will identify all sorts of problems and do a better job of it than a compression test alone.

I will find a garage to do a leak down test for me and then see what that says

Thanks

Absolutely! Sorry for that!!

you can have knackered rings and decent compression, if oil rings let oil past the oil can help to seal the compression rings when you test it.
