Yea like a ticking noise but im not 100% sure as the car is quite loud lol. But yes i thought maybe a header leak but i snugged the bolts up a little and its still making that sound. I dont have a tester thats worth a darn, i could rent one when i go to the store obviously, but would i be able to easily tell if i just took the valve cover off since its quite easy to do?Like a ticking noise?
You mentioned a header leak, I didn't pick up on that. Run a compression test.
