or could be cambelt tensioner..

you might stop the tappets ticking if you change to a better oil..

Motul 15W50 300v Competition for example..

Or is a fairly expensive job to change all the tappers (16 of them) as it is hard to know which one is ticking.

Piston slap is best described by doing a search rather than me retyping it all etc.. but basically the piston clearance is too great causing the piston to slap the bore.. usually only heard when the engine is cold unless very bad and you can ignore it pretty much.

Hi,
Maybe just a thought but I had a noise which sounded like maybe the big end's but I finally found out when my crank pulley almost came off losing the drive belt in the process .Just an idea but try checking the crank pulley bolt to see if it's tight (torqued correctly)
