Ill have more on Monday. Long story short, replaced lifters (#1 was very soft) put back together. Yet the tick continues rolls in, rolls out. When cold - no sound ( oil thicker ) , above 3k rpm tick goes away. Rev engine and it goes away also. Indie did some more adjustments checked tensioners etc. So just going to drive it for a bit. Indie says, "car drives great just this lingering tick" . Ill be able to make a recording and posted once I have it back and then go from there. BTW prior oil changes have shown nothing in the filter BUT ..... Indie detected some liquid gasket material. Apparently from the pan being dropped and inspected 8k back on last service by PO (known by former maintenance docs). So it continues

I have to stress is it very important if the camshaft covers are removed that they are properly installed. The type of sealant used, how big a bead of sealant to lay down, the routing of the bead of sealant, the proper fititng and tightening of the cover (and more) are all crucial to getting the camshaft cover back on the head and bolted down metal to metal contact so the cam bearing, half of which is in the cover the other half in the head obtain the correct shape/size. Additionally all high pressure oil passages that have oil flowing from the head up into the camshaft cover are sealed and do not leak out high pressure oil under the cover.

Scoping the cylinders is fast and easy, and totally non-invasive. I wouldn't be comfortable with spending the money and time to replace lifters for "a ticking" without doing that first. Hope your mechanic isn't charging you for hanging parts.

I wouldn't say it's fast nor easy, it will be a couple of hours labor to remove the sump plate, scope the cylinders from the bottom, clean the plate, re apply silicone and re install...
but yeah - I'd be getting it scoped before looking at lifters myself.

I hope this works. The address for Media Airdrop. Video sucks but right side of the car for ticking. Not wearing right clothes to lay under ride. Driven 5 miles back to the homestead. Thanks for the input

being phone video its hard to judge but i do have to say it doesnt sound as loud as other bore scoring video i have heard or piston slap I have heard on other brand of cars before. Have you pin the noise to which cylinder? with stethoscope may be able to get closer to the source (i.e block, the head, closer to which cylinders)
I think someone above have mentioned that it could also be injector noise.

Could not get it narrowed to one spot. I can retake from under the car or lid up and inside.Then post up for all to peruse. Went to pick it up the other day and it threw a code P1325. Apparently it is cam alignments being off ? Ill know more today. Thx Dr Strangelove for the youtube help and remember no fighting in the War room. Thanks for the input. The saga grows.

That good it threw a code, might be a simple fix.
mine never threw a code. Even with severe scoring in cyl 4 & 6 never threw a code. In fact if you ignored the knocking noise and the massive amounts of oil burning, you wouldn't even know. Idled fine and always pulled like a train.
