I have a lifter tapping after the car has been sitting for a month. Dirty is prolly the wrong word, as much as dry. Then again...the motor has 170k miles on it so I shouldn't be surprised. I use Wix filers and Mobil synthetic in everything, pretty sure it's not cheap oil or a cheap filter.
Lifters have the tightest clearance in the engine, when dirt enters this area it wears down on the lifter and it becomes a loose/dry lifter because the tight clearance is now loosy goosy and the lifter wont shut up cause it wont hold the same pressure anymore for the time needed.
Regular filters are poor quality as far as filtering performance, the industry/manufactures recommended filters are mostly 20/40 micron nominal and just wont protect engines, this is why the short drain interval is necessary.
But the big secret is most filter manufactures make a filter with better filtration performance but they are never advertised.
the WIX 1734XE is one of those filters, it may be 2x as expensive but why do they make it?
