What oil have you been using?
Does your low oil pressure light work?
I would pull the oil pressure relief valve and check that the piston is free to move.
Pull the VC and look for deposits.
Change oil and fish out the sump with a wire loop through the drain bolt hole. See anything strange?
I am cocnerned that there might be a sludge or relief valve problem and that the chain tensioner changes in sound reflect oil pressure changes. Gets quiet when the tensioners get more oil pressure?
If the noise is slow ticking at idle, probably sticky lifters. If buzzy, the chains. I don't know how one tells the TC from the timing chain.
