carmoliva

I have a 2000 Z28.
When my car is at idle I can hear a slight tick. It goes away with higher RPMs.
Seems to be coming from the bottom of the engine, so I don't think it is the fuel injecters. Anyone else have a similar prob or know how I might fix the tick? <img src="images/icons/frown.gif" border="0">

Re: carmoliva

Could be an exhaust leak..

I get the tick tick tick from a ORP leak...but can be fixed easily...I bottomed out and bent the clamps... <img src="images/icons/mad.gif" border="0">

If the tick tick tick was coming from the top it would be valvetrain most likely...but since its coming from the bottom its probably exhaust...

Re: carmoliva

valve train in the ls1's are quite noisy, but if its from the bottom i would check all the joints where the exhaust meets from the manifold/header to the cats to the y pipe....
