I posted a question a few weeks ago about getting an occasional cold lifter tick on my 2008 Silverado. It only does it when it's really cold and been sitting outside for an extended period of time (truck is garage kept). It is an '08 so it is part of the notorious early AFM issue but I have AFM tuned out. I was previously running M1 EP and got no tick but higher consumption than I liked so I switched to PP which I had ran about a year earlier. As soon as I switched I've had the cold lifter tick a handful of times which leads me to believe it's the oil. But, in the thread it was mentioned that it could be the Wix filter (or just filter related) and it was suggested to go with a filter with a silicone ADBV.
I checked and confirmed with Wix that their ADBV is silicone for my truck. I also confirmed that the Fram Ultra is Silicone. I also have some PF48, pre E-Core's left along with the UPF-48's which are supposed to be identical to the old PF48's internally.
Does anybody know if the AC Delco filters have a silicone or nitrile ADBV? With how the filters are mounted on the 5.3's, could it be the filter that is causing the cold lifter tick?
Also, I ran a Wix filter with the EP and got no tick so that kind of rules out the filter causing it, correct?
It was suggested to try a thicker oil so I've thought about trying Castrol Edge since its CCSV and MRV numbers are a little higher which means thicker, correct? Or should I go with a thinner oil so it flows easier at cold start? PP HM has slightly better numbers than PP.
Suggestions? I know I'm not going to eliminate the consumption but I'd like to solve the cold tick problem.
