2014 Chevrolet SS Silver
Maybe we're just getting old, but this is the noise that I grew up with in small blocks. Could be that there are more people today that grew up with VVT engines and overhead cams.....
Thanks for this insite...to be clear with everyone, I don't necessarily think what i hear isn't "normal".. It's why I'm here brainstorming with you all... But, I also don't write everything off either. Especially, when random people can "guarantee" there is no problem.Early LS1's had a piston slap at cold idle that many mistook for real issues. I even bought a 98 TA for pennies as the owner was convinced that piston slap was a knock. I know that this has been designed out for the most part, but I still occasionally hear it in cold LS2's.
The valve train on most LSX's I have worked with all have the sewing machine sounds at idle with some noticeable ticking that could be normal valvetrain noise and/or fuel injectors.
Funny thing as soon as you think you hear a tick, you focus every bit of energy on listening for that tick and possibly falsely convincing yourself there is a real problem.
In my experience if you had a broken rocker, failed roller or cam lobe, or bent pushrod you would definitely know.
I run mine without the engine cover, and can definitely hear valvetrain/injector noises at idle. These noises is the exact reason that cover is there.
I also don't think that at idle the peak cylinder pressures would be anywhere near detonation levels...87 Octane would not cause detonation at idle.
I think what you are hearing are normal LS noises...enjoy the car.
Well, for starters.... It burbles if the little black button on the dashed is pushed when your foot is on the brake.I definitely will still enjoy the SS to the fullest! I'm just not as familiar with the noises this engine makes, yet.
Ha-ha! I see what you did there...Well, for starters.... It burbles if the little black button on the dashed is pushed when your foot is on the brake.I definitely will still enjoy the SS to the fullest! I'm just not as familiar with the noises this engine makes, yet.
It will sound like a deep long belch as you ease out leaving a stop sign.
But the noise that gets everyone's attention is how it bellers when you push the pedal on the right going from 50 - 100 while passing a line of cars on a 2 lane road.
So there's 3 noises you won't need to take it to the dealer to have checked.
