Any ideas on a ticking sound?

[Drew86maro]

Hello, Well I have a ticking sound coming from my GTP and its driving me nuts not knowing what it is! The car runs and drives perfect, plenty of power, shifts fine ect. It only makes the ticking sound between 2-3 thousand rpms in forward gears. But heres the catch, when im in park or neutral it wont make the sound? Now i had a similar sound in my 86 Z28 and it ended up being my exhaust manifold gaskets but not sure what it is on the GTP. Thanks for any input guys.:th_winking:

I not really sure what it could be , but a video might help us out on trying to determine the problem

I will try to post one but im not sure how great the sound will be. Its not loud enough to hear inside the car with the windows up plus the supercharger whine will drown the ticking noise out. And if the windows are down (thats when i hear the noise) the wind noise will be to loud for the camera. And i cant do it when the car is in park or neutral cause it doesnt make the noise then. And when i rev the car with me outside of it doesnt make noise. I have to be between 2-3 thousand with the windows down to hear it.

Fuel injector ticking? Maybe a lifter/valve train noise? And input is greatly appreciated :th_winking:

Exhaust leak would be my guess

Could be noisy fuel injectors.

Could be noisy fuel injectors.

Yeah im starting to think it might be fuel injectors. Whats the best way for me to find out if it is or not?

Get under the hood and listen to the injectors while the car is running.

you can use a mechanics stehascope (wrong spelling), and put it on parts of the mtotor to determine sound, If the injector is clicking, you can prolly put the scope right on the fuel rail and hear it, then you got to find out which one it is.

A big up screw driver will work too.

 

[Drew86maro]

OK i'll give it a shot. it only makes the noise when i drive the car but 'ill see what i come up with. Thanks

Are noisy injectors a problem?

Im about to change my thermostat in about and hour or two when my car cools off and i'll try that screw driver idea and post some results by the end of the night. Thanks for the help guys.

Ok so I put a screw driver on both fuel rails (front and back) and I heard a clicking sound that sounds almost identical to the noise i hear while driving between 2-3 thousand rpms. So is that my problem? And should only 1 fuel rail be making the sound or both if an injector is noisy?

basically its your injectors.

Run some seafoam with your gas and see if it helps.

OK. But is there there anything else besides sea foam that could get the job done? i mean i'll use it if i have to but i have mixed emotions about that stuff. thanks

injector cleaner?

 

[SDGTP99]

Or go with new fuel injecotrs if you feel you must.

I'll give that a shot and see what happens. Thanks

Naw not right now. But if it gets louder or make the noise constantly then i'll def look into a set of new injectors. :th_thumbsup-wink:
