hi there


my Car is Chevy Caprice 2007 LS with 3.6L - V6 ( this model 100% as G8 2009 3.6l )
Mealge is 110000 KM ( about 65000 mile )


I have noisy lifters sound since 1 year

I've tried flashing Oil but and different types of oil but no difference the sound still the same

dealer says , I should change Oil pump and open engine head to change lifters but that cost XXXX$ !

How I know the problem is from Oil pump or Lifters ??

plz check my video to hear the sound ( make the sound on youtube 60-50% )

Measure the oil pressure when the lifters are making noise. If the oil pressure is good then it's the lifters.

But you had the lifter noise since 2008, that's 6 yrs. if it isn't getting worse, I'd live with it.
