Gary's updated CCV thread

OK, it's not Gary who's starting this thread, but I hope he jumps in and start giving us some feedback of some sort.
Gary buddy, you said you will start this thread very soon. So I started it for you. Now spill the beans.......
I know I have to refresh my CCV this summer, and I need to know where I'm sitting. Don't want to buy another winter version, only for you to come with the news 2 days later that Gary's new CCV is out.

doru,

You crack me up, I laughed for five minute after I saw this.

I've been trying to get a few minutes to respond to this ever since you made the post, but my week has been horrible. I do have some updates regarding the testing we have done with applying full manifold vacuum to the crankcase without the pressure regulation of the CCV valve. I will try really hard to post something tomorrow. I just wanted you to know that I was not intentionally ignoring this.

Gary

OK, waiting on updates then. Can't hardly wait.

Don't forget the dipstick guide tube retrofit when you re-engineer the CCV system ...
- How can we clean out a clogged oil dipstick tube (connection to CCV)?



And, CCV testing procedures:
- How to test the BMW E39 pressure-controlled crankcase ventilation system (CCV)?

Don't forget the dipstick guide tube retrofit when you re-engineer the CCV system ...

The kit is going to include a new redesigned dipstick tube.

Gary

I have the re-designed dipstick tube. Will this be the same as yours?

The current design incorporates the updated OEM dipstick with additions. If volume allows, we will make our own entirely in house.

Gary

Thanks.
How long do you think until the redesigned kit is commercial?
P.S. : i think I will be among the first ones to snag it......

I'll be right behind you doru!

Personally, I think it's better to reward Gary's team with our orders for the redesigned dipstick tube guide sans the concentric rings than to give BMW even more money - which, in effect, rewards BMW for their faulty design.

:

I am almost positive that my CCV is again done for....

I had a retired BMW master tech. (after 28 years) read the live codes on my car last weekend.
He said the catalytic number was 14, and should read 0, and some other number (I can't remember what...) reads 4, and should read somewhere around 14...
Hence, the reason for my hesitant acceleration when hitting the gas...
He said the timing was retarding...
And, he said the car's high crankcase pressure is the reason for my car's failed oil-pan gasket, and why my fuel pump is making noises (suspected failing again - pump was replaced just last year).
He first suggested replacing the Purge Vent Valve, then later, said to spray a whole can of B-12 carb/throttle body cleaner through the throttle body while the car is running...
This sounded kind of "old-school" to me...

Thoughts....?

I am so tired of changing/replacing this damn CCV...

Thanks!
Jason

What is the purge vent valve?

I think it is this:

Ahhh!!!
OK, thanks Jason. Weird how that pesky CCV can cause so much trouble.
Why is it that the M54 engine has more oil pan gasket failure than the M52? Is the CCV designed different? (If the oil pan gasket failure is due in part by failed CCV)

Yes, I think it is ALL related...!
Notice, the only oil pan gasket repairs you read about are on M54's...
Coincidence...?
I don't think so...
Plus, I think the bad CCV is causing Oxidation and Nitration within the oil (varnishing-up and becoming acidic)...!
Very BAD...!

I found this great article about Oxidation in Oil:

http://www.midtownoil.com/downloads/...ting%20Oil.pdf


Pretty interesting…......

"While controlling temperature and using higher-quality base oils can help limit the
degree and rate of oxidation, the eventual breakdown of the base oil molecules due
to oxidative processes is inevitable."

I also found another great article:
http://www.bobistheoilguy.com/whatisoilanalysis.htm

"Oxidation measures gums, varnishes and oxidation products.
High oxidation from oil used too hot or too long can leave sludge and varnish deposits and thicken the oil."

Nitration:
http://www.bobistheoilguy.com/forums...t&Number=16187

Nitration results from the heating of O, O2, N2, OH, and H in the
cylinder during combustion. The separate gasses mix
and when burned, form many resulting gasses
including NOx.

NOx generation is highest during: high
pressures, high temperatures, during crank angles between 10 and 40
degrees, and when the A/F ratio gets near
16:1, such as in lean-burn engines.

NOx gets into the oil via the blow-by gasses
during the power cycle when the cylinder pressure is highest and when
when the temp of the burning gasses is highest.

EGR valves and large overlap cams introduce
exhaust gas back into the cylinder to cool it down, reducing generation
of
NOx.

NOx creates peroxides that attack the oil and
increase oxidation as well.

Now for updates on other products:

CCV - Minimal progress, but I do now have a rapid prototype for checking fitment and tweaking dimensions. I will be back on this heavy in about 2 weeks and hope to have a sellable product by the end of the year.

Thanks for your patience,

Gary

So there is hope.........

It seems to me that the core of the redesign is the CCV, which is mostly common between the M52TU and the M54 engines, and it's a problem on both. Hopefully this means the 528 owners get one too! I'm good to beta test!

Contrary to how it may appear, there has been some progress on this. I want to assure everyone that there has not been any issues with the initial design concept, just time on my part to make significant progress.

I am waiting for a second version of FMD rapid prototypes to come back so we can continue fitment testing. The problem is the tight clearance around the oil filter housing, intake VANOS solenoid and valve cover venting port. We are trying out a longer version with a different type of cap nut. Once we can verify a good fitment position that allows easy access for servicing I will get started on actual metal prototype parts.

I think most of you have noticed that there is an automated email link on the website that allows you to sign up for CCV updates and get first dibs on the first production units. There have been so many responses to that link that it is helping me try to find more time to fit this into my development schedule.

On another note:

For those who are not aware of it, we have released our 1.2bar coolant caps and will be releasing our M62-tu version of cam tools early next week. We spent a huge amount of research and development time on both of these products and we are very proud of the results.

The coolant cap should drastically reduce cooling system explosions and the M62 cam tools are a big inprovement over the factory tools in accuracy, ease of use, and most of all, affordability.

Thanks everyone for your support, patronage and patience,

Am I still getting the first one, Gary? :-)

Yep

Woohoo! My car really needs a new CCV!

I thought the purge valve was for gasoline, not oil?

Maybe I misunderstood 'which' purge valve - but if it's this one - it's for gasoline:
