Exhaust leak or lifter

[scagle777]

I have an 05 Sierra 5.3 with 108k. I noticed a tick coming from the right side today. I can't hear it when I open the hood, but if I put my head down by the front tire I can hear it. I figured if it was a lifter I could hear it from the top as well but I'm not 100% sure. I know that manifold leaks are very common.

Hold a rag over the exhaust pipe tip. If it's an exhaust leak you will know exactly where it's coming from.

If you take a look at your exhaust manifolds, you may have some broken bolt heads. I've read a few threads about these bolts breaking and some causing exhaust leaks. Currently I have one broken bolt but it hasn't annoyed me enough to fix...yet.

...and check if the spark plugs are tight.

 

The lifter ticking on my truck turned out to be a lose spark plug.
