ck your oil level make sure it is up to the top line........................you have a clasped lifter does it quite down when it gets warm
loose exhaust
try checking the lifter(s)
Clutch throw out bearing bad.
Lack of oil lubrication to the valve lifters.
Serious engine knock or valve train noise. Have this looked into by a pro.
In most cases, you can tell that your lifters are bad, in your car engine, by the ticking noise. A bad lifter will make a tapping sound.
it could be your driveshaft. I'd get it looked at if i vvere you.
hydraulic lifters.
Get bin Laiden
Is it a lifter ticking?
Most probably the noise is piston slap, this noise is heard when the engine is cold and disappears when the engine is hot. if the slap is very strong when the engine is cold and the noise becomes less when hot but still the noise can be heard.
if you turn the key and nothing is making noise check the battery if you are trying to start it and it is making noise press the gas a little bit so that the car can pump gas into the engine
