Probably just paranoia. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I just picked up my 2LT last week, car JUST hit 100 miles. I can't help but notice an engine knock. I'm assuming it's because the engine is brand new and it hasn't really figured out the correct fuel/air ratio yet, but I don't really know. It kind of sounds like a valve tap, but it's intermittent, most noticeable at idle.

Any opinions?

get it checked out.should not be making any strange noises.

Some say the high pressure direct fuel injectors make a little noise, but I haven't noticed it. Definitely no "knock". I agree with others, let dealership check it out.

2010 SSRS · 03-16-2010, 02:00 PM

bring it back to the dealer

I have a 2LT with around 9,000 miles.....never heard any knocking, even when it was new. Get it checked out.

I think I know what you're reffering to. At idle, I can hear the slightest "ping" noise, but I think its just the nature of DI.

HeavyD · 03-16-2010, 04:21 PM

DI are noisier.

DangerZL1 · 03-16-2010, 04:27 PM

Drive by the dealer and ask to listen to another V6 and see if it makes the same noise.

Yeah, this is pretty accurate. It's more of a ping noise. When I go to the dealer for the first service I'll have to ask them about it. They may have even put regular gas in it when they did the initial fill up. I haven't had to gas the car yet so maybe it'll stop when I toss some 93 in 'er.

You have a V6....You should be running REGULAR gas in it, there's no advantage to using premium, other than spending more of your hard earned cash for fuel.

Oh? I heard that regular gas could still cause a slight tap in the engine. Though I can't say first hand because I'm still on the first tank.

I noticed that with my car as well, only if the radio is off as it is hard to hear. The direct injection is noisy and I heard that it will only get noisier as well, as the car ages.

MaryC · 03-18-2010, 03:31 PM

Are you using premium gas? The owner's manual says if you do not, the engine will knock.
