So wondering how to diagnose engine noise. How to tell if it's a exhaust leak vs something coming from the engine?

There is a gentle tap tap tap on idel that get louder when I step on the gas. Say when I'm cruising and I let off the gas the it goes quiet. It doesn't seem to get faster when I rev but it does get louder. It's a b16a of unknown version on straight pipe. New spark plug new oil. I did recently took apart the head and reassemble it to fix a even louder tick. Now that that tick is gone I'm not sure if this noise came from me taking it apart or it was there the whole time just mask by the even louder tick I fixed.

Having it look at in two weeks for this and other problems.wanna get an idea whether I should even drive it during the two week. It running on a tank of 87 gas that I put in months and months ago so j really want to ran it down and try some higher octane gas.

EDIT: it's got no cel. Fuel pressure seem good around 35psi
