So ****! I just got "everything" fixed or so I thought. I had to replace all cops, plugs, EVR, and fixed my exhaust leak. After I changed the X-pipe and fixed my exhaust leak I got a SES light that has since gone away on its own. Not sure what that's about and I didn't get it checked so now I'll have to go to a dealership to diagnose it.

Anyways I just drove to Kragen for some new brake pads and as soon as I pulled into the parking lot I started hearing a ticking sound at idle. it gets faster with higher rpms but seems to quiet down. It sounds like its coming from my passenger side head. haven't taken a hose to it yet but It sounds like its further back on the head near the throttle body. But it wasn't there at all yesterday and now its loud enough to hear over my exhaust from inside the car. it just literally started out of no where. I'm going to run some fuel cleaner to see if maybe its an injector (had similar issues w/ my 240). If its the timing chain though how rough is that to repair? I will try to get a sound byte of it but I don't really have anything but my iphone to use so we will see.

Sounds like an exhaust leak from the passenger side manifold. You sure you fixed it? Those gaskets are a PITA

Ya I'm pretty sure I fixed it, it just sounds as if its one component out of 4 ya know. like my exhaust leak wasn't a constant tick it would change with rpms, engine braking, amount of throttle, etc.

This is just like a constant unchanging tick at idle and increases proportionally to rpm. it sounds valvetrain related to me but my 240 had a dirty injector that clicked so I'm hoping that its that!

I'm stumped. When mine was leaking, it was loud and embarrassing- and it did like you talked about, being proportionate with rpm.

Either way, getting under there with a breaker bar and tightening the living **** out of those two bolts wouldn't hurt. If that's not it, I'm sorry, but I'm clueless bro :(

Ya trust me I tightened the **** out of those bolts, I just fired it up and unplugged each COP one at a time and it didn't go away. I am going to try to unplug each injector to see if its one of them.

It's most noticable inside the car, when I put my ear in the engine bay its hard to distinguish but now sounds as if its coming from the intake runners, like in the middle somewhere.

Mines making a similar noice as well, im leaning towards an exhaust leak on mine tho, even tho at first i was dead set that it was my valve terrain (all new components, thought i forgot to tighten something up) now when i start it, it almost sounds like theres a small leak? so idk man, i know that to change timing parts its a PITA

could also be your timing chain guides. they are notorious for going bad. I experience this with a ticking sound coming from my D/S valve cover. checked it was actually coming from the timing chain cover. It would tick/chatter at initial start up for a couple of seconds then at certain speeds and certain gears it would come back. :2cents

hey dude....stop whatever your doing and check your plugs...mine did the same exact **** and spent every day for like 2 weeks trying to figure out, then I gave up and did a tune up at the end of the month. went to pull out the old plugs and bam!! 2 loose PITA's

im kinda hoping thats not my problem, once the weather cools off more and its time to hibernate the stang, im gonna pull the front cover off and take a look at all that stuff. idk i hopes its simple like tightening the exhaust. but we'll see! haha

yeah, it could be your plugs as mentioned as I know that they are notorious for blowing out.

running rich if they're chalky like that but at least its getting burnt and not building up too much...the gap is decent from what i remember, like around 48 possibly?? google factory specs

Yes I agree that exhaust leaks are annoying as hell! I would park far away from everything so nobody could hear it! soooo embarrassing.

And as far as plugs being my problem I just changed them all with the COPS, (btw, gap is .050-.055).

So it has gotten louder in the last 8 hours. I can hear it all around the car so I'm really starting to think part of it is the exhaust but I can hear it in both exhaust tips, and it doesn't sound like the exhaust leaks that I've heard before. And I just got rid of one like 3 days ago... Tomorrow is a day off so I will be going through it all day.
