Location:Appears to be originating from front of engine block, around valves or exhaust ports
When:Rarely at idle, quiet at 2k, increasing in volume at 4.5k, drowned out by engine noise above 5k.
Louder if engine is under load due to a decrease in regular engine noise.

could have bad exhaust gaskets i had a 2000 f4 with that similar sound and it ended up bein the exhaust gaskets where worn down and one of them was even rattling which caused that ticking sound at certain rpms
