The dreaded NOISE question
hi .. 2015 C7 coupe with 6800 miles since April. A "rattling noise" like the old "tap tap " from lifters coming from what seems like the area behind the Info center. Had 7500 mil check done. My tech of years said that it's "injectors" and that the noise should subside beyond idle. However, it has gotten louder in the last month; occurs not only at 800-1000 rpm in neutral but also at 1200-1500 rpm in neutral or drive ( A8 tran) . LOVE my car but can't believe that this noise is "standard equipment" as per the tech. At a light, it's LOUD. Ok ... Corvette owners are sensitive to anything but the "tat tat tat " can be heard above the radio etc.
Ideas or experience with it ??? THANKS < Bob

Other than that I agree with your Tech; these DI's are very noisy and at times can sound as loud as lifters clacking. I pulled into a McDee's drive through and sitting next to the wall running with the window down my car sounded like a wash-machine with rocks in it. They are noisy and for us picky or gearhead vette guys can sound a little irritating. BUT every time I nail it and it comes to life it puts a smile on my face!! LOL

THANK YOU for replies. I bought car with ZERO MILES and as mentioned, noise was not as evident til about two months ago. AGREE 100% that the performance is stunning. I'm going to dealer tech next week to drive car with him. Will mention your comment on the plate. Again, I can't believe that the factory would not have noticed a noise like this one on every car and considered it ok for this group of fanatics!

I don't worry about noises, they come and go as the mileage accumulates. Unless the engine isn't running properly (dreaded check engine light) or fails to run I don' t get to concerned. If there is a loud clunk and the engine stalls with a large puddle of oil on the ground then time to be concerned.
