Ok so here's the issue. Around 20 miles After my heads/cam swap coil #7 started making a ticking noise. I already swapped the coils, spark plug, plug wire and made a compression test on that cylinder. compression came out to 210. If i disconnected the coil the tick stops or if i disconnect the injector. the car still has to be taken to be tune. Would the noise go away after the tune? or any advice. any input would be appreciated.

Thanks guys..

i've hear of injectors making a ticking noise, try swapping it to another cylinder and see if the noise follows, try the same with coils

I use a old school method, Cut a piece of water hose about 2' long and put it to your ear and move the other in were you are trying to pin point. It work really well to pin point a knock or tic.

Never heard a coil tick but an injector will. As stated take 5 minutes to swap the injector around and see if the tick follows....

well i already swapped the coil and it still made the noise on the same cylinder. so that's out. I'm going to swap the injector to see how it goes. and try the hose method in the injector.

thanks for the input

maybe a bad plug wire,swap the plug wire to another cylinder.

Make sure the spark plug is in there tight. If it wasn't sinched down it could've backed out creating a small leak that would tick.

I like that hose trick, I'm going to use that one.

What kind of ticking? Maybe it's inside the cylinder itself. Pushrod lifter spring. Yk?

I spents months tracking down a ticking noise from my passenger side after a header swap. Turned out to be a loose spark plug, just had to barely turn it 3/4 of a turn to tighten it and the ticking vanished! I don't know how it got loose as I tighten the sh*t out of my plugs when I install them. Oh, and it turned out to be #7, LOL. The hardest spark plug to get to, for me anyway.

It's your injector. coils don't tick...

Might be a header gasket leak.

while its dark out. start the car and look for spark under the hood. if its a loose plug or wire you will be able to see it.

Problem solved!!! but not fixed... well I've been pretty busy swapping a engine on my lt1 this week and today took a quick look at it. With the engine cool i turned it on and got my hand to the header on the cylinder #7 nd i felt a small leak there. So iam pretty sure that's the issue. So maybe it's just a loose header bolt.

Thanks to u all for ur help..
