Wait a min! YOU don't know that most modern oil filters are built to bypass in the event they become restricted due to whatever reason thus allowing oil to still flow through the engine? Well then it just can't be then I guess because if you don't know about it, it obviously doesn't exist , RIGHT!?! Besides oil flow to critical engine parts isn't that important, RIGHT!?!I have never been in a situation where an oil filter would bypass oil. I routinely cut my filters open to inspect and never had sludge or debris to cause this. I am try to buy quality products to ensure good filtration. I am so use to working/rebuilding vintage engines with oil filtration that is partial filtering. Still, your argument holds no water as the other lifters have no indications of water or non filtered oil as you call it. If it were that issue everything would have the issue not just one specific area.
You keep citing all these years of knowledge and shop ownership and nasa approved underwear, yet you have not brought anything to the lifter failure table that is new, logical, or seemingly going anywhere. This here will also be my last post involving you. Only an idiot will stump his toe against the rock so many times without either walking around it or moving the rock.
I'm going to find a trail with smarter rocks.
On top of that, then maybe you can explain all of the cam and crank failures I saw while at GM of the 4.8L, 5.3L and 6.0L that all had pitted lobes but only when oil changes were 10-15k miles apart because customers and all were going by the oil life reminder system?!?
As far as, "bringing nothing new to the table", REALLY? Is that why I was told that the lifters I "have in the bucket are the EXACT same" as the ones I was stating I was gonna pull from the 19 Hellcat engine? Yea there identical other than the larger roller (which is what I said in the first place) and the addition of an oiling hole in the oil groove of the lifter body itself! Other than those 2 differences they're exactly the same.
You have fun with your fingers in your and running in circles while screaming, "la la la la! I'M NOT LISTENING TO YOU!" I'm sure that'll serve you well when you grow up. Or maybe you could listen to people who have far more experience, at least with these vehicles/engines, than yourself and deal with them on a daily basis.
I'll bet you'd argue with your cardiothoracic surgeon about what's wrong with your heart citing that your buddies next door neighbors cousins best friend said it was something else and that the surgeon is way off base!?! Then while attempting to walk out of his office you drop to the ground then try to sue him!?!
