Default Engine knocking or tapping noise

My 04 v6 stang has a bad knocking/tapping noise. I removed each spark plug wire one at a time and started it. None of them stopped the noise. It also has a Check Engine Light on. Im lost.

Do you have access to an OBD scanner? If there's a check engine light a good place to start would be to figure out what code it's spitting out to trigger the CEL. Unless of course the CEL is a result of having your spark plug wires unplugged, but I'm assuming that's not the case since you bothered to mention it.

May be a dumb response, but I don't know what you know about cars, so I'll say it. When I had my first car, I had an annoying ticking like that as well. It never went away and it got faster as the engine reved. I had about 1 out of 5 quarts of oil in my engine...

Check your oil. If the sound is exactly like that sound in the video and gets faster with acceleration, then oil is at least a good place to start

My two cents.... I had a ticking/knocking issue with my 2000 that I couldn't figure out. I had everything checked out changing the oil and everything with no results. Finally I took it to a friend and we figured out it was a cracked weld in the exhaust manifold. It was so small that when the engine was cold it would allow the exhaust to pass which made the ticking sound. As the engine warmed up the manifold expanded and it went away leading me to believe it was an oil/lifter issue. I had the manifold welded and reinstalled and it runs great now. This might not be your problem, but it's worth a mention just in case. Good Luck!

oh man that doesnt sound good at all, you definitely need to find out what your check engine light is all about. it could be a good hint as to what it is

I think I paid around $250-$300. I thought about doing it myself, but then the mechanic scared the @!%& out of me saying that if I broke a bolt I'd have to have the heads removed etc to fix it, so I paid to have it done.

Any one know if it sounds like a stuck lifter? Or a bent push rod? And what is the trick to get the pass side valve cover to slide out? It has some smoke coming out out the pass side valve like its not gettin oil. Thats y im thinking lifter.

Hmm, my brother has a '96 v6 with a sticking lifter and it sounds like that, but it's not that loud...hard to tell over the camera... does it ever go away or get quieter?

I just took the pass side valve cover off and one of the pushrods was loose. I could even rotate it.

Well, i did some research. I saw they are suppose to spin. But the rocker arm closest to the fire wall keeps getting loose enough to have play and I can rattle it back and fourth.
