That noise is most likely valve chatter. Unless the contact points have worn significantly, this will likely quiet down if the oil is fully topped off. Check the oil; if it is still making the noise and the oil is full, then either the cam lobes are starting to get worn or the ticking is coming from another internal component.
Subaru's, especially older ones, are famous for valve chatter. People (around here anyway) like to say they sound like sewing machines.

Thanks all for this forum! It's great to have a place to bounce ideas around.
So currently I have a 1998 subaru legacy L thats overheating. All the fluid levels are good and the thermostat is new. Noticeable lack of power and some new mechanical noise coming from engine, doesn't sound like valve lash but just as consistant. Oil light keeps coming on and only cold air blows from the heater. I think possibly cracked head......any insight on this would be great.

Unfortunately, I think you on the right path. The DOHC EJ25 engines are prone to head gasket failure. Once combustion gases get into the water jacket, you get air pockets that prevent the heater core from providing warmth to the cabin, and causes hot spots that do further engine damage.
If you act quickly, you might be able to save the engine. Run it like this and you will kill it quickly.
