Help!! Loud ticking nosie from the engine
2001 Z06 all of a sudden a loud ticking noise coming from the engine.
What could it be? Even when the car is on idle and warmed up the noise is quite loud.

In my minivan i also had the ticking noise was loud, the mechanic would always recommend some MMO( Marvel Mystery Oil) and it would quiet the ticking sound completely, i dont know if it will help, but figured i would just give you some info , good luck

Its better to fix the problem than to hide it with snake oils. Put a stethescope to the valve covers and find the noise. You might wnat to pull off the valve covers and look for and damage, bad lifter, pushrod...etc.

Could be a sticking valve too or maybe you lost a valve retainer clip. Of course, the first thing that comes to mind is a lifter as already stated. The lifter will usually pressurize and the noise will abate. But if it remains constant, I would suggest locating it first, pull the valve cover and get a quick look at the rocker. You could have lost the needle bearings in the rocker itself...has happened to people before.

Now if you do have this mod I would expect you have upgraded valve springs meaning duals.
You may have broken a valve spring and the inner spring has saved your butt.

I'm wih TCMC5 ... check for exhaust manifold gasket leaks
or air tubes - my headers have small cracks where the air tubes
weld on and they make a distinct ticking sound. I also had a
(dual) valve spring break but it was Very obvious- ran terrible.

I hate to even ask this but: Did you change gas stations or gas? I bought my car and it was knocking when I got it. I think the previous owner put some regular unleaded in it. I got to a station where I knew the fuel quality and filled it up. The knock went away within about an hour.
