View Full Version : Ticking noise at idle?
07-20-05, 04:43 PM
OK my caddy will be going in the shop next week and I am beginning a list of things for them to check. I have a noticeable ticking noise from seems like the right side of engine during a normal idle. Is this normal or should I bring this to their attention for some conceren?
Thanks in advance

Welcome to the world of the LSx motors. Mine ticks exactly the same. The LS6 along with the other LS motors out there all have a noisy valvetrain. Some are worse than others. One of the reasons Cady put on the engine cover.
I think all the GM 5.7 engines I've owned have ticked like my V.
Just turn the radio up a little bit:D

If you avoid idling, you shouldn't have the problem. Try WOT instead. It's more fun. :)
Every GM V8 I have ever had ticked for as long as I can remember, back to the late 80s. I keep telling myself not to worry about it. The other noise that bothers me (that they all do) is the sloppy belt sounding noise. I want it to be all tough and mechanical and there is this swushing sound. Also present on every GM V8 I have had since . . .

You may also be hearing the fuel injectors tick.

Would not expect it to be valvetrain with a hydraulic roller cam, hadn't thought of the injectors though.
