ok my car started making a loud ticking tonight its been making a really quite one for a while now but only between 1000-1500 rpm tonight it started at higher rpms it seemed toto start after a 30mile drive. im hoping its just a exhaust leak but im having trouble pinpointing it. the car is full of oil i check and in the video you can even hear lifter tick along with the noise. im sorry about the quality hope you can hear it well enough to help


thanks jake


Better ticking Video l67 - YouTube

Sorry, I can't make anything out in the video.

Have you tried disconnecting the serpentine belts and starting the engine to eliminate the accessories?

Well after driving it today the sound isn't there so I'm pretty sure it'* just a exhaust leak that shows after long periods of driving

Huh, weird stuff eh?

Maybe try up on hoist and tighten clamps/flanges slightly.
See if there are any put put air leak sounds while up there.

Yeah I'm thinking about just taking it to a exhaust shop and having a smoke test or something done it came back after a long drive again today. Other than an exhaust leak would anything else cause a ticking after the car warms up. Here is another vid I did its loudest if you keep revving it vs holding the throttle so mabey you can hear it better

well finally was able to get my mom to help me tonight by having her rev the car while i got under it i wasn't able to pin point it exactly but the noise was much louder under the car and it sounded like it was coming from the downpipe area. and now that i think back i hit the bottom of the car pretty hard on a rail pulling into the carwash the other day

Could be a broken exhaust hanger, or the heat shield on the cat is broken and rattling now. Are you able to put it up on ramps?

Well a little update on this. I'm still not sure what it is. I took it to exhaust shop and they said they didn't see any leaks. So i took it to general maintenance shop and they listened over everything with a stethoscope, and i was told that no abnormal noises were coming from the valve train, and all he could find was a bad pulley and a loose tensioner, but they were grinding not ticking. Then i had my friend look over it, and he didn't think it was a exhaust leak or internal either, and though i should start checking accessory, or just wait till it got worse and easier to find.

Take both serpentine belts off by taking tension off the tensioner and start the engine. Does the ticking go away? If so, reinstall the belt that runs the alternator/power steering etc. Restart it. Does the ticking come back? Or no? Now reinstall the supercharger belt. Restart it. Noises?
