    2011 ESV Lifter Noise

    I have a 2011 Escalde ESV Platinum. Although I am supposed to recieve free maintenance, I have reservations about the dealership experience. Over the years, there have been too many times where my vehicle was dented, scratched, or had complications from an easy repair.

    My problem is a sporadic lifter noise at start up. Sometimes, the noise will last a few minutes. Most of the time, the car starts and sounds fine. I have changed the oil twice. The first oil change I used the GM Dexos oil. The second time I used the Mobil One that is Dexos rated. I see that GM has a bulletin for 2007-2011 6.2L with a lifter noise. Instead of changing the lifters, can I use an oil additive like Amsoil or Lucas? Once a motor is taken apart, it is never the same. I grew up around cars and I belive there is no substitute for a factory motor. The seals, tolerances, and gaskets last longer when installed by the factory. It is for these reasons that I will not let a dealership mechanic touch my vehicle. Please let me know if you recomend an oil additive and will it void my warranty?

    I traded in a 2007 Suburban LTZ (6.0L) for this vehicle. It had the same problem but seemed to get better as the vehicle had more miles. I am afraid of doing damage to the camshaft. I do not drive the vehicle when it is making the lifter noise. I let it idle until the noise subsides. Other than this, the vehicle has given me no problems.

    Thank you for taking the time to read my post.

    It sounds like the lifters are bleeding down too much, I would think that a thicker oil would help this, but it's only really masking the problem. If they truly are noisy, I'd get them replaced. I know you're concerned about seals and all, but you've gotta have nearly 4 more years of warranty left on it to cover any leaks, etc!
