Another "What's that noise" thread

[japanda]

Hello! I have a 2013 sonic rs
The dealer replaced the injectors, temp sensor.
There is a tick from the purge solenoid and still the injectors which I'm not concerned about.

I have this intermittent louder ticking, it comes on at start up, middle of driving, maybe not at all one day, or all day driving. The vehicle will stumble and hesitate during this as well

Have you tried eliminating the valve cover, intake manifold, and corrugated hose coming from the intake manifold to the turbo to make sure they are functioning properly?

I had a very similar issue recently (I am also near 89,000 miles) and I ended up having to modify the intake manifold. The little orange rubber check valve inside was completely gone.

Are you still having issues?

Any update on this issue?
