156 v6 ticking noise???

Hi all. I have a 156 v6 on a 1999 plate. Just recently, my engine began making a ticking noise which appears as though it's coming from the back of the rear head. It's like a tapping noise. My mechanic advised me to use some valve lifter mixed in with my oil, but to no avail.

Does anyone have any info? The engine has done about 100k miles, never had a real problem, and there doesn't seem to be a lack of power which makes this a little confusing?!

It could be many things.
Could be an exhaust gasket leak, but could also be the water pump, loud injector, coil pack cracked, worst case chunk of coke floating about in the rear bank cylinders.
Keep a close eye on oil and fuel consumption both tell tale signs.If there is no discernible difference in performance it should not be anything serious.
