Yes, we recommend every 3,000 miles or 8,000 km for anyone looking to extend the service life of the vehicle out to 300,000 miles or more. For full disclosure, I personally drive a 2007 Yukon Denali with the 6.2 L engine that currently sits at 293,566 miles or 472,452 km. My oil change interval is 5,500 - 6,000 km or every 3,500 miles. I bought it new in 2007 and I still use it as a daily driver and I regularly use it to haul a 8,000 lb travel trailer. It's still reliable, dependable, and the best part - totally paid off.

In this case, a minor oil leak around the valve cover was left for an extended period of time until it had began dripping onto the exhaust system and burning up. The vehicle owner detected the burning fumes and wisely chose to seek immediate service.
A vehicle with a leaking valve cover should be repaired promptly for several reasons. Firstly, the valve cover plays a crucial role in sealing the top of the engine, preventing oil leaks and ensuring proper lubrication of internal components. A leaky valve cover can result in oil seepage onto the engine block or other hot surfaces, which poses a significant fire hazard. Moreover, oil leaking from the valve cover can drip onto other engine parts, such as the exhaust manifold, leading to unpleasant burning smells and potentially causing damage to surrounding components.
Continued oil leakage can also result in a loss of engine oil, which can lead to inadequate lubrication and increased friction within the engine. This can accelerate wear and tear on vital engine components, potentially leading to costly repairs or even engine failure if left unaddressed.
Additionally, ignoring a leaking valve cover can lead to environmental pollution, as oil dripping onto roads can contaminate soil and water sources.
In summary, repairing a leaking valve cover is essential to maintain the safety, performance, and longevity of the vehicle, as well as to prevent environmental harm.
Thanks for the question!
