ticking noise coming from under the valve cover when give it gas it will tick faster. any suggestion? valve clearance maybe?
7afe ticking noise - 6G Celicas Forums
Had the same problem with my old 7a. Did a check on the clearance and everything was fine. I was told it was rod knock. When i replaced my motor i didnt pull it apart to verify. Wouldnt hurt to check the clearance. I never read up on the supposed rod knock. Something i should do.
solid lifter engines like the 7A can be a little tappy. Try a little heavier weight oil if it bothers you. Also injector tick was VERY pronounced at idle, throw a towel over the injectors and listen again. If it is them and they bother you that much you can fashion a cover out of sheet metal and spray foam to cover them to help silence.

^ What he said. Put your ear right up to the injector bank and you can hear them well.

This is allll good stuff and right. I had a valve adjustment done two years ago (before that, the ticking was insane) and afterwards, I could still hear a light ticking. It's just the injectors.

Ticking can be annoying, but it isnt bad coming out of the cylinder head. Its knocking that you need to worry about if you hear it. Make sure there isnt an exhaust leak and check your valve clearances. Move your hand around close to the exhaust manifold where it bolts to the head. You will feel hot puffs of air if there is an exhaust leak.

i was thinking about removing the spark plugs wires one by one to see if it will effect the ticking noise, what do you think?

Wouldnt hurt. All of the above would def. Narrow it down
