Another engine-related issue is leaking valves. To handle this problem, maintain your engine by regularly checking and replacing worn-out valve seals and gaskets.

The transfer case could develop issues in your Hummer H3 as well. To prevent this, have your transfer case inspected and serviced regularly.

Lastly, pay attention to your spark plugs. If you notice poor engine performance or misfires, it might be time to replace them. Regularly inspect and replace your spark plugs to avoid potential problems.
