do you run 10w30 or 5w40
5w40 this change. I’ve changed the oil as well as the dealer.What oil do you run? Do the oil change yourself? Do you prefill the filter?
Mine has an infrequent tick and I'm debating just going with the flat tappet conversion to fix it permanently...
I prefill the filter as well.
That’s exactly how I do it.Not sure how you prefill the filter, but you should only prefill thru the outside holes. When you prefill the center hole all that oil, and it’s contaminants, will go thru the block unfiltered.
Virgin oil is not that clean.

Do you happen to have any data supporting this. I recently came across a YT video in which they did a pretty good comparison on this exact subject. I get this is a YT video but the poster is credible based off his previous jobs and he appears to be pretty knowledgeable on this topic.
I may be one of the few on this but I always and have always prefilled my filter and I personally believe by not pre filling you are increasing your chances of damaging your cam/lifters. On the engines I have built I always do a prime on the oil system before cranking, having all the oil passages filled with oil makes a huge difference on first starts. I do understand our oil pumps move a great volume of oil in a short time. However, it only takes seconds for damage to occur and our filters are not small by any means and hold a descent amount of oil. There have been several posters on here claim they start to hear a tick right after an oil change when leaving the dealer, has anyone on here had a tick begin when they prefilled the oil filter? To dive a little deeper on this how can an oil change cause a tick? The only change I can think of is the minimal loss in oil pressure on initial start up as the oil filter fills. Our lifters are already poorly designed as is, for me id like to keep a constant supply of oil going to them at all times.
I have never pre filled a filter and i have done hundreds of oil changes, we also have a 12V with 1.8 million km never once pre-filled the oil filter. There is no risk not pre filling as said the system has oil throughout it. I have always primed new builds thats just common sense. My 19 has never ticked after an oil change and the filter has not been pre filled.Do you happen to have any data supporting this.

While the oil passages are filled with oil they are not moving oil until the filter is filled, there has to be pressure established for oil to flow.
exactly i can make an engine oil pump pressure spike and reduce the flow by blocking the bypass and adding a smaller orfice does not mean the engine is better off id rather have lower pressure and higher flow to a certain extentAlso, pressure doesn’t establish flow. Pressure is the resistance to flow. The oil pump establishes flow, and the engine provides resistance to that flow creating pressure.
Although this is technically correct... oil circulation through an engine or any machinery requiring lubricant to be forced into tolerance areas (bearing surfaces) or especially when using the oils hydraulic capability to empart mechanical force (hydraulic lifters)... The lubrication "system" requires both flow and pressure.Also, pressure doesn’t establish flow. Pressure is the resistance to flow.

I have always believed it was a block machining issue as the design of the lifter is nothing new as far as hydraulic roller lifters are concernedAlthough this is technically correct... oil circulation through an engine or any machinery requiring lubricant to be forced into tolerance areas (bearing surfaces) or especially when using the oils hydraulic capability to empart mechanical force (hydraulic lifters)...

Since going though this lifter tick nonsense with mine I personally believe it has almost nothing to do with pre-fill or not, 10-30 vs 5-40 etc etc..
These lifters and their bore tolerances are just not as tight as they should be and what we are seeing in the overall small % of effected trucks(though it should be 0) is the ones that develop this issue as they break in(normal wear not initial) allowing unintended lifter movement on sometimes multiple axises.
Please don't think I'm saying this applies to 100% of these "tick trucks". Of course there are other outside variables that are niche but overall the evidence points to these aforementioned concerns.
My truck is in for the second attempt to "fix".
Cam/lifters didn't work... Came back basically immediately. Upon further investigation of #6 lifter bore(intake I think) found damage from either casting flaw or assembly... So I'm waiting on a new block now.
So I'd catalog mine as niche.. Even from my own opinion about this issue as a whole.
