valve noise at start up
Ticking noise at start-up. Sounds like valve noise, but goes away when warmed up. Checked oil level which was fine.
The most likely cause would be an exhaust leak. Exhaust leaks sound just like a bad lifter,and usually get quiet after engine warms up and everything expands. Check exhaust donuts.
I have the same problem with my 2004 Envoy XL. Did you find out what the problem was?
