could be hydrolic lifters are worn
or
oil level is low, and theirs not enough oil getting to the hydrolic lifters so they tap

they have knock sensors so shouldn't pink......
Injectors 'tick' but no loudly.
Its probably worn or dirty lifters. If you take them out they can be cleaned with some parafin. Or they are about £6 each new i think.
They should get quieter when the engine is warm and when the car is reved as the oil gets thinner and the pressure increases when reved.

i think pinking is wen the engine is burning lean, causing the engine 2 run hotter and will therefore lead 2 ceasing the engine if not looked at
