well i just replaced my lifters on my 2008 mustang v6 4.0 and when i did my oil change i notice the car had a weird ticking noise and rpm surge when idling. Aswell when i travel car from a dead stop and give gas car will tick. Does my car sound like it has valvetrain noise or is it worst?
the car does have misfire and a bit of vibrating when it does misfire in idle.
we did a compression on it and all cylinders were 150psi and oil pressure is good.
idle ticking 13sec mark

Hard to hear ticking.But what was the arcing in the second
video? either voltage leak or camera issue. If you run the
car with the valve cover off.You may get a better look at where
the noise is.I think you could be hearing the sound of the fuel injectors opening and closing. Some cars the noise is quite loud. With the plastic intake plenums they use today they tend to magnify the sound even more.
Take a long screwdriver or stick of wood and put it against your ear and an injector (if you can get to one)to see if that’s the noise you are hearing.
the ticking sound started when i had a misfire on cylinder number 2 and ever since ticking sound has been there. The day i had the misifire we took the spark plug out and it was grey and the electro of the sparkplug was shut there was no gap, but to be safe we did a compression test and eveything was the same 150psi. the reason the misfire happen was because i had bad gas and found out it was mostly water and that is what caused the misfire. though since this is a used engine my previous one blew up, the lifters gave out and we replaced them and it did reduce the sound but still it is there. do you guys think it is valvtrain noise related or piston and lower related?
also the sound on the video of revving that is the sound it does when you rev it or when you take off but in a tapp tap tap rythme.
yes the shop that pulled them told me they were collapsed..but thats all changed i dont even know if they inspect the rest valvetrain parts..but lifters did fail.
Did you ask the shop that did the lifter work what they thought about the noise? curious about the spark plug with the collapsed electrode, have you rechecked it since replacing it to see if it has collapsed again? I was not able to play the video you posted of the noise.
i try to make a youtube account to post them there so you can hear the noise..and yes i told them and they were like the sound was gone that was the problem, which is true while the sound in idle is gone of the ticking there is another one that was unresolved which is the first video and the one on the 2nd video is the one that also stayed when giving it some gas. we did check the plugs again and car hasnt closed them no more. the car does have a misfire in the exhaust you hear it puff puff as it is missing.
Is the puff puff sound rhythmic like a ticking clock or are there gaps of time between the puff puff sounds?
I listened to the videos-they did not help me much. Since the puff puff IS intermittent my next diagnostic steps would be first to mist spray some water on the plug wires and any secondary ignition components you can access to see if the misfire or rough idle gets worse. My second step would be to check all vacuum lines and connections. My third step would be to do a cylinder leak down test starting with your number-2 cylinder. I feel you may either have a burnt valve or possibly some excessive valve stem/guide wear issues. These steps do not directly address your ticking noise concern UNLESS the ticking noise is being caused by electrical arcing from a failure somewhere in the secondary ignition sytem.
when the instant happen of the misfire but my dad tried to put my spark plugs in my aluminum heads thinking they were iron and he messedup my thread so they installed some thread fitters but on cylinder 2 the spark plug dont enter fully since they left the fitter bit out, so maybe that is what is causing the ticking cause the car runs fine and all but with a ticking noise and a miss on idle cause compression was equal. also when you dont give it much gas it wont tick as soon as you give it a good bit of gas it tick?
Can’t say for sure about the spark plug thread/insertion issue relating to the ticking noise unless you are losing compression at the number 2 spark plug area when the engine is running. you have so many variables with this situation that it is too difficult for me to begin to isolate the problem. You need to find someone with good experience and some time to dedicate to work through all the variables you have with your situation. i wish I could offer more help but without being there I can not. Let us know how you make out.
