I started my car and the low oil pressure light came on . After that i heard a metal clank sound then this ticking
Sounds like it's a lifter/tappet (they are hydraulic activated with oil) that needs to be adjusted, and/or it's not getting any oil. Sometimes it can get blocked with just a little bit of "dirt". The low oil pressure light will come on when you first start the engine but should go out when the engine runs and oil pressure builds. As for the "Clank" sound - that could come from the intake or exaust valve because the lifter/tappet did not have oil in it at the time, and is still not getting enough oil.
Better get a mechanic to check it out before you drive it very much.
Could be a lifter or piston pin with no oil.

does it go tick tick tick tick and when it warms up it stops or goes quiet?
its your lifters not getting enough oil
when u change your oil it will stop till that oil gets worn out
you will have to replace the lifters or it can also be a slack oil pump not pumping oil around the engine like it should
SOURCE: ticking noise and low oil pressure
DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

Hi There,
I would try adding a lifter quiet supstance such as nulon lifter quiet, may or may not be available in your country,
Or try heading to a local auto store and look for a reputable brand name products, ie injector clean/ carby clean /lifter quiet/worn engine treatment.
Below i have listed common problems related to yours that might be worth checking.
Sometimes the oil that you may of put in may not be thick enough hence why youre getting more noise.
it could mean yes that a lifter or shim is loose and needs adjustment,
injector noise from fuel injectors if they get clogged up they tick loudly.
Dirty fuel causing injector noise
Low oil or incorrect oil level as in over full.
Incorrect oil specification/ wrong Viscosity or grade.
Leak or low oil presssure could be a blockage somewhere stopping oil circulating
Worn oil pump not correctly pumping enough oil.
Oil line blockage insufficent oil getting up to the lifters
It coudl even be driveline related as in a C.V. joint coudl be loose/worn and ticking.
Ive even seen cars where wire has been entwined aroudn the driveshaft and taps against the floor/wall
Coudl be a fan if your fan runs off the engine rather then electric ticking against the houseing or it could also be a belt or bearing in one of you accesories ie a bearing in the aircondition clutch tha tmay be loose and is ticking.
However start small and go from the cheapest option up to the dearest.
Make sure you have a good listen while its running with the bonnet up and go through to try and find the source of the sound.
Usually this is what the mechanics would- do anyway untill they find the problem.
Hoipefully this helps so you dont have to take it to the shop.
Cheers
Steve

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

SOURCE: it has low oil pressure, ticking sound,and loss in
You are in need of a new oil pump, drop the oil pam off and replace the pump, DO NOT DRIVE THIS UNTIL THE LOW OIL PRESSURE IS REPAIRED OR YOU WILL NEED TO REPLACE THE ENGINE
