Sterling, just to correct some misinformation: Our engine was damaged with the RPS carbon-carbon clutch in place, not the Tilton clutch. That CC clutch was great when new but developed severe chatter. When it failed the Tilton concentric slave was damaged and stiff, the clutch plate rivets were loose and coming apart, and the thrust bearing was toast. That all seems likely related. What is not related is the fluid, which was not silicone-based. Tilton specifies DOT 3 or 4, and not DOT-5 silicone-based. (Same for brakes, BTW).
Bleeding a Tilton hydraulic slave is simple: There are two lines, pressure and bleed. Air rises so the bleed hose goes on top, and you generally push fluid from the master-- or suck from the bleed, shouldn't matter. The one thing you cannot do is attempt to exercise or bleed the hydraulics without the clutch in place and clearance set, there is no stop on a Tilton release bearing.

Just a minor detail to realize (kind of in the same category as figuring out to plug the computer into the wall outlet.)
And correctly routed clutch hoses will not rub through. I did make a tiny change, to the instructions (and added one clamp to the entire kit), to make sure this does not occur.
Correct, one ring gear did come loose, because of a dimensional issue on one flywheel (which I did not make or install and could have not possibly known), but we notified every other owner to tack weld the ring gear to the flywheel, just in case there was more than one, with this issue. (There are still several of these "first batch" of flywheels running around, without any tack welds)
"Remove lower bell housing and apply 3 tack welds." (We did several, in house, which took a grand total of 30 minutes to do.)
Nothing remotely close to a major design flaw on an absolutely wonderful clutch/flywheel system.

Holy crap, Sterling!
If all of your written attacks over the past 8 months are all about my absolutely wonderful flywheel and clutch?
Just pack it up, send it back, and use something else;
I'll gladly refund your money!
You, intentionally, have done more damage to me, my business, and my reputation than the profit on me selling 100 of these wonderful clutches and flywheels would ever be worth.
Congratulations! So happy that I even sent you one!
Now let's see if you know how to play real hardball.....
Look , I know you made it your mission to conspire to put Carl out of business.
And I have written proof that you, Roger, one moderator, and one other individual have conspired to do the same, to me.
(Sterling, you are not the only computer "hacker" in the country. The people I know make you look like a junior high school computer "expert".)
Realize that I'm not going away....and we absolutely will all gather together, in California courtroom, to hear this all
Libel is one thing. BIG financial implications, for all!
However, conspiring to do financial damage to another's business and reputation, is something completely different, with completely different results!
And going to jail is not out of the question, for conspiracy to do this kind of harm. (Actually, it's become fairly common.)
Keep it up, guys!
Keep trolling and trashing my business and reputation.
Keep up the Emails (and other communications) to each other regarding your "conspiracy" to defame me and my business.
We've got every single communication and know exactly what to subpoena.
You guys might be smiling and laughing, with each other right now, about what you have done to me.....
Just remember these "pearls of wisdom":
"Always completely know the capability of whoever you choose to screw with, long before you start."
And:
"He who laughs last, laughs best."

I have come to the conclusion that you will say any thing about any person that makes products for the 928 unless you have made them any thing made is NOT GOING TO WORK unless you made it spoke to the guy that made the oil neck baffle and he told me that you said that that would not work because of part missing as for the question about the valve cover plates i have not read the post on Open Road but he said there are pictures of some one having your plates fitted to cam covers that look very a like to yours and that they became available around 2018 so to say they won't work and make the problem worse the conclusion is then the first batch you sold were not tested but how many have you sold of this type before now saying that the newer versions work make your mind up or is it just lies so they buy yours
OK guys, as you were!
Reminds me of the Rodney Dangerfield's joke that he went to a fight and a hockey game broke out

I guess you stirred up some hidden feelings/bad blood or something.
Funny, the way your inquiry ended made me wonder what will happen in 10-15 years when we're all older and starting to forget stuff.
Hope I'm around to enjoy those 'Rounds'

Clearly covered in my post #23. Not functional. Will, most likely, increase oil to intake.
Whoever bought these copies got conned by Potdog.
LMAO
In order to properly steal proprietary products, the entire "system" needs to be stolen, not 50% of the idea.

On-topic, there is a simple 27$ oil control fix that works. (track tested) It's Similiar to what Porsche used on the Boxster.... that was pointed out to me on RL and had I known that I may have tried to repurpose the Porsche item. I used a BMW M52 cyclonic oil seperator, shown below, pictured upside down.
It works. No baffel needed, no need to crack open the valve covers.
I was black flagged a few yeas ago for blowing oil smoke while on track, I added the M52 seperator and have had no issues since. The BMW item has 3 ports and is shown below pictued upside down. The included hoses can be relieved of their qucik release ends and they can be repurposed on to the end of standard hoses routed in the 928 engione compartment.
Port 1= Oil in from valve cover breathers T'd 2 to 1
Port 2= Oil drain back , connect to oil pan level sensor port
Port 3=Vapor port out...connect to existing air intake box inlet
Steal my 27$ idea, I'm not the first one to think this up and I wont be the last. The fact that it's so low cost is just a reality of the global trade circusmtance we all live under. Even if it was 20x the cost it would still work and be a good value. There are people running around with high dollar race O/A seperators that dont work as well as this one with its cyclonic design. I've seen this first hand at the track. BMW probably spent thousands developping this and the design can be yours, guilt free for a very low price. Buy one at your local BMW parts counter if that works for you.

Greg would not sell a set for my shop to install while I had my cam covers off. I would have gladly bought them from Greg. I PM'd him to try to have him reconsider and that the shop I was using in Florida was very reputable, to no avail. He indicated it was one of his closely guarded products (even though I had read emails where he was shipping them out in the past). No other explanation given. I was disappointed, and a bit surprised.
So, yes, it happens.
