Engine noise
I have bought my first c7 stingray. It's a base convertible. The car has 13000 miles ac and it's a 2016. The day I bought it sounded fine but it was 70 degrees. Now it is 38 degrees and it's making a noise when it's running. It sounds like the valve train is very loud. Is this somthing that is normal on a c6. Any help would be appreciated. Thanks for reading.

The ticking noise is the main control solenoid on the high-pressure fuel pump and is a result of the high pressure at which the direct-injection fuel system operates, about 1750 psi (port injection operates at ~ 45 psi).
I find the engine to sound a bit like a diesel.

Thanks for the help. That's right sounds like a diesel. This morning I got a diagnostic report from onstar that said I had a problem in the Engine Transmission that needs imidiate attention. Take to dealer.

It is possible there is something wrong and what you are hearing is atypical. Ask the dealer when you take it in. I suggest also checking to learn if they have a used C7 you can listen to, checking for the noise.
Normally the noise is not all that loud. You should not be hearing it inside the car with the windows closed or while driving.
Please report back and let us know what you learn.

Ok I couldn't figure out how to get the videos posted but I did talk to a couple of vette people and they listened and said that is typical lifter noise from the LT engine fuel management system. My question is if I buy the plugin that goes under the dash that is supposed to keep the car from going into 4 cylinder mode will that help the valve tick some. Sorry I forgot what that plugin is called right now but it cost about 200 dollars. Thanks again guys.

The Range Technology device will stop it from going into 4 cylinder mode but will not help the valve tick.

If it is valve tick does that mean it wont make noise until it warms up because I just drove it and it made no noise until the temp came up on the car about 3 miles then you could hear it. I will try to upload videos.
