So recently there has been some ticking noise coming out of my engine and i’m worried it could be blown, hoping it’s just spark knock, recently my nearest gas station wasn’t offering 87 which i always use and so i put 89 octane in and i noticed a difference in power with the truck but now when it warms up i hear a ticking noise that gets faster with rev but around 3k rpm’s it goes away the truck isn’t throwing any codes but when u get near the muffler after it’s warm and been driven it sounds like it’s missfireing and the bay makes a tick noise like two wrenches taping eachother

 

Also when i let it cool down it goes away or when i rev it it will stop it’s very quiet but noticeable when u pay attention

 

Hows oil pressure? Last time you changed it? What oil is actually in it? Maybe an exhaust leak??

 

oil pressure looks fine i’m gonna do a oil change soon, but i started it up this morning sounded fine guess it might be a exhaust leak but i’m not sure only does it when it’s been driven for a while
