Engine trouble

Hey guys whats up. My engine now more then ever has been clicking at idle. And it seems to be getting worse by the day. Ive noticed that after my recent oil change it got worse then before. So what can I do to my engine to get it running smoother. Is there something that I can do before I have to take it in to a shop? Please help.

the ticking is most likely your valves. do a valve adjustment. if the ticking remains then its time to start looking else where for the problem…maybe injectors? i know they can make ticking sounds.
