Question about 1986 Jaguar Xj S
You might be able to 'flush' the engine oil, with an engine oil flush product, then change both the oil and filter.
This might work, as the followers can become dirty over time and dirty oil, not being changed as offten as it should be, otherwise, if this fails, you will be looking at new parts.

How loud is it, did it suddenly get loud? they should have a light noise if gapped correct, easy to check, the covers come off with about 11 7/16 nuts, slide a feeler gauge blade a few thou less than the specs under the cam when the lobe is pointing up, a few thou bug is fine but if it gets to 6 or more it will be noisy, look for a wearing cam if one gap is big, also check the chains for slop.If you are in the UK the library can get Haynes manuals in, keep it clean for them!
