FWD or RWD..?? You don't say which you have..??

Hasn't popped a freeze plug has it..?? There's one on the head exhaust side.

Perfect pic of the core plug in the head..! Could also be the EGR cooler leaking...not unheard of.

A video of the sound would/ may help people here diagnose the tapping.

Put it on youtube

Taking the auxiliary belt off and running for a few seconds ... would tell you if any of the ancillaries .. is causing the tapping .
