If everyone insists it wasn't the filter I'll try it again eventually. I have a m1ep for it for the next OCI. It's been perfectly silent since I swapped filters a couple months ago. And like I said several others here stated that some of these engines don't like the Ultra.It’s not the filter causing you grief. I run the ultra guard and runs quiet. I ran ac delco, wix, and fram. No issues with any of them.
Dump some sea foam in the oil and give it a hard run. Change the oil.
The filter is installed vertically. Oil doesn’t drain out.
I'm worried about those potential issue, but I haven't noticed any lower oil pressure on a cold start yet.One thing that might cause you issues is the o ring on the oil pickup tube is leaking. It will lower the output of the oil pump. I just changed mine out when I did the oil pan gasket.
It's an 05, doesn't require dexos, but I'm running full synthetic in it now. Currently m1 EP HM 5w30, previous fill was Qs HM FS. It's one of the quietest of these engines I've ever heard. No noise when warm, barely noticeable piston slap on colder starts below 0.I have the same motor-run mostly Ultra and ACDelco. These motors are/can be noisy. Good luck chasing an issue which doesn't affect long-term longevity.
You don't say what year the truck is-but those motors require Dexos-which no conventional oil (to the best of my knowledge) carries that approval. So there is that elephant in the room as well.
The Ultra-as stated is a fine filter with low flow resistance.
This is what caused my 4.8 tick.One thing that might cause you issues is the o ring on the oil pickup tube is leaking. It will lower the output of the oil pump. I just changed mine out when I did the oil pan gasket.
If that's the problem in my case, switching the oil filter temporarily eliminated the tick. If I have to do it eventually, I have to do it, but it will be an expensive repair because it's 4wd.This is what caused my 4.8 tick.
Yeah, mine is RWD so it wasn't too bad.If that's the problem in my case, switching the oil filter temporarily eliminated the tick. If I have to do it eventually, I have to do it, but it will be an expensive repair because it's 4wd.
Yeah mine is RWD, so it wasent too bad. I've also used all types of filters and oils, and none of them caused a tick. But I can see how it can be tricky diagnosing the problem.If that's the problem in my case, switching the oil filter temporarily eliminated the tick.

Earlier I said I was currently running the extra guard. I was incorrect. It is the tough guard. The one down from the ultra. I have no issues since I installed it, I was just looking to see if there was one at the same quality/efficiency level as the ultra that my truck would be happy with.The Fram Tough Guard is advertised for this kind of service, can’t hurt to try it.

Except I'm one of 2 others that had the same experience just on this site. Otherwise I would have tried different oil before trying a different filter. It might not fit but I'm also not crazy or imagining a solid tick.The fly in the ointment is that the Ultra should flow better than the EG or TG, so someone claiming the Ultra makes their engine 'tick' because it's "too restrictive" (which doesn't really happen with PD oil pumps except in rare circumstances) doesn't seem to fit.

If you're that insistent that I'm wrong then I will give the ultra another shot. This time I'll record the engine idling before I switch it out and right after, for comparison.
