I just noticed your edit.
They are or are not magnetic?
Ti is non magnetic. So if the magnet sticks, it rules out Ti.
If they aren’t magnetic and also aren’t Ti (failed the fire test) It means that they are very high In Molybdenum, Chromium, and Vanadium. This also means that the parent metal should not rust.
The VW lifter that I have here is very magnetic.
Ti, when disturbed, leaves a slightly less than shiny gray matte finish. The stuff is super sketchy to grind, because if you start making sparks, the dust could ignite. So lots of coolant lol.
Certain grinding applications of Ti, are actually ground in a low oxygen atmosphere to prevent auto ignition.
I noticed that too. So they are not magnetic? Now I am very curious. Do you have access to a scale to weigh them?
The only way I can see titanium working for the lifter material is if it had a coating applied with an extremely high hardness and low friction like DLC or a some of the PVD (Physical Vapor Deposition) options.
I suppose its possible for the M159 Black Series which has a higher 8000 RPM redline, as titanium would lower the lifter mass pretty substantially. It would also justify the crazy price tag.

The coating would certainly help, but I think if they are titanium, it’s probably an alloy of Ti. Maybe 321 stainless?? 321 work hardens like a *******.
I still think lifter mass would have a minimal impact. What would really settle that for me would be seeing a car do a dyno run before and after the lifter swap with the same cams and maps.
If the mass has that much of an impact the engine should fall on its face when the heavier ones start to cause problems.
I don’t buy crappy batteries anymore. I usually stick to interstate. Almost every vehicle I own took a battery this year.
A8= $225
S4=$170ish
F350= $184 x 2
VW=$165
Ive had it with batteries this year.
I have to say, I used to keep a few cars at a time(3), plus my truck.....that was a lot of bills for a lot of things....kudos to you. Being the evil genius you are probably helps a little to mitigate headaches lol Anyway you look at it, that's a lot of batteries though.

ya, interstate is solid. I now buy my batteries from AAA. Interstate for something in the range of 180-240. battery crapped out within the 2nd year and they warrantied it for a replacement. I now have a 900CCA Deka from AAA. This thing probably costs a hefty sum. AAA roadside is awesome if you have it in your area.
MB tax= $340 bux for a battery Gotta love MB! It did last 8 years though....which is sort of unheard of.
Not looking forward to see what MB Australia charges for a new battery.
Auto parts store battery is around Au$400
My battery is 7yrs old so I know I'm on borrowed time.
Still starts strong even after sitting for a week or so.
If I'm purposely leaving it sit for a while I set up the trickle charger.

Deka is a damn good battery. Just not available here. The black plastic in the cases is mostly recycled from (I used to know what but can’t remember). The reason I know this is because I used to work for the outfit that used to (or maybe still does) rebuild all of their plastics compounding/processing equipment.
Unless anything has changed, they were based out of PA.

Woah, high praise here that I’m not sure I’ve earned yet. I still need to follow through on my promises.
Its really not as bad as it sounds. The truck and the A8 are both antiques now, and the S4 is 16 years old. No payments there. Just repairs.
I’ve always said of old Audis, every single one of them comes with an unpaid $10,000 repair bill. Unless you can fix them yourself. I bought the A8 in 2013 with 107k for $3k and have put about $15k into it. The S4 I paid WAAAAY too much for, and it needs a damn laundry list of stuff.
With regard to my promises, I have been moderately successful at a recent machine shop auction, and on Monday I’ll be hauling home 10,000 pounds of old wartime American iron. I hope to be operational enough to start turning out some work by Feb sometime, and fully operational later on in the year, by appointment.
After all, I still have a full time job as a real machinist.
My car will likely be the first one to get the bulletproofed “KamiJusters.” I’m going to put my money where my mouth is and put them in my car to prove it.

I'm not sure about the recycled case material but their QA on the agm stuff was pretty stringent. They are based out of PA, I worked there for 5.5 years as a maintenance mechanic. Just so happened a fellow coworker leased my car and wasn't keeping it so it practically fell in my lap for 10k off retail!

Im more of a traditional plate anode/cathode kind of guy. Never really run an AGM battery.
I used to drive a tow truck in the winter when I lived in New England, and my truck had Dekas. It always cranked over at 0 Frankenstein. Didn’t always start, but it cranked over.

I have been toying with the idea of oil squirters and do have some ideas. I’ll cover that at the end of this post.
.
Why not get use of oil already there?
Volvo design in old redblock got a 'splashguard' that collects oil that is pulled up from the clearance between lifter and head, and also collects oil from the bearings.
This makes the oil stay longer to get more chance to lubricate the buckets and also acts like a oilbath when engine is coldstarted.
They have NEVER had any problems with worn buckets.
The splashguard is cast into the head in the volvoengine, if watercutting some alu sheetmetal and bending it clever, it might get the same function when engine is running, not creating the seal to make the coldstart oilbath thou.

the rail at the red arrow.
VW did something similar with the old 8v which used the same lifters as the old Volvos. It’s probably why those old engines lasted a million miles.
VW did it to keep oil spray from going into the PCV I always thought. Most of them end up getting removed because they get deformed and degrade from the scary high oil temps present in those old cars.
I think the problem with the AMG heads is a lack of oil to begin with, but I definitely think it’s worth looking into seeing if an oil dam could be installed in the AMG head. I’ll have my valve covers off in a couple weeks to install a set of my camshaft phasers so, I’ll be taking some pics to that effect.
8v head “Cam baffle”
The VW cam below is rusty because it’s been out of an engine for a decade or more. But same technology as the AMG heads. Quarter million mile VW 8v camshaft. From one of my old VW engines.
Yes, volkswagen and audis have the same design.
And IF deciding to make some oilsquirt, look at Ford Pinto engine, they´ve got a thin metal tube fed with oil and drilled holes.

Thats certainly the idea I was going with. I already know where I’m planning on tapping the oil supply from. It’s just a matter of getting it to fit under the VCs. They sit very tight to the head and don’t leave much room.
VW/Audi/Volvo use the same exact lifter in the early engines. Right down to the last dimension.
The only differences are cylinder spacing and valve spacing.
I´ve also been looking at making a 'controlled leak' from the bearings to the inlet cams, somehow mill a groove so oil can seep out onto the bucket, just where the camshaft 'hits' the bucket.

Gotta love MB! It did last 8 years though....which is sort of unheard of.
