Free Fix for Constant Pressure Valve

[soma]

HI All,
I am offering to post to the UK:
1. Viton Fluoroelastomer O-rings (23 high-temperature compound o-rings)
2. My custom-made 3mm x 4mm Kincrome impact drill bit
FREE OF CHARGE!!!
to anyone who wants to fix their constant pressure valve oil leak

All you have to do is do the same for a fellow forum member. Once you are finished with it, pass it on to the next bloke again and again until the 23-O-rings are used up.

I have been inspired by Pingu's excellent write up on how to fix the leaking constant pressure valve (thanks Pingu!!):
http://www.zroadster.net/forum/viewtopic.php?t=31401
In order to remedy this issue, Pingu gave instructions on how to machine grind an impact drill bit, the most time consuming part of this do-it-yourself job. In addition, replacing the OEM O-ring with another has proven to be only a short term solution as high oil temperatures adversely affect the rubber compound. Therefore, I have followed the recommendations from bimmerforum to use Viton Fluoroelastomer o-rings (1.5mm wide/14.5mmID):

I have 23 O-rings and my custom-made flat-head bit ready to go:





If you would like to do this job, I would be happy to send you the tool and o-rings as long as you pass it on the next forum member.

Just PM your address and I will post it straight away
cheers, SOMA:D

What a gracious offer

[shantybeater]

Very kind of you Do we know if this affects s54 engine as well?

Shanty, below is a quote from Pingu's original post.

The constant pressure valve (11 11 1 318 185) is fitted to the S50B32 and the S54 engines.

[pingu]

soma. well done fella.

[soma]

Thanks again Pingu for a great write up.
After ordering the minimum number of o-rings, I still have heaps left over and the tool is 'job specific' so might as well pass it on.
I reckon if anyone is getting ready to do an oil change, might as well replace the constant pressure valve o-ring adding only an hour or so to the job.
I don't think M owners realize that the OEM O-ring becomes harden and brittle rendering it ineffective at maintaining oil pressure. I agree with Pingu this may constribute to vanos failure.

[shantybeater]

In that case I'm definately interested, my next service is probably a few months away though so someone may want to jump in before me? If not I'll happily go first

[soma]

Great Shanty....lets see if others are planning to do this fix sooner. If not, I will send it along to you ok?

[shantybeater]

That's fine with me

[pingu]

...adding only an hour or so to the job.

It's a 15 minute job when the car is already on the ramp and you have the tool.

I'd get it negotiated in with the price of the service. .

[soma]

Only 15 minutes....all the more the reason to get this sorted if you have a leak...surprised I've only had one offer so far.
I suppose the Northern Hemisphere is getting a tad chilly this time of year for working under cars eh?

Hi All,
just posted the 'Free Fix' kit to Shantybeater. If anyone wants to take this project on themselves, he will gladly pass it on to you.
cheers< Soma

[RST Driver]

Great offer.

Could anyone of you please send me just one of these Viton O-rings? I think I can grind the tool quickly myself but I'm really interested in one of these rings.

Who would ship one to germany?

Best regards,
Phil

[soma]

[shantybeater]

Shantybeater, did you send the O-ring to my address?

Best regards,

I did indeed, has it still not turned up? :s I can send another!

Mark, I can send one over to you as well but you really need the tool to make life easier, there is a bit of a queue now though ! I'd PM althulas and sonic (above)

[RST Driver]

Not yet. Maybe I have to wait another few days.

But thanks for shipping one o-ring to me. =)

Phil, PM me your address again for confirmation and if it still doesn't appear next week ill send another

[RST Driver]

Finally got it from James, thanks again for that great offer!

What is the tightening torque for the valve? Anybody knows?

Best regards,
Phil

[shantybeater]

^^ good question, my car will be going in on tuesday for its InspI+brake/coolant flush so i'll be getting my garage to fit the seal at the same time. When I get it back on wed/thurs I will send the rest onto Mark (althulas)

[RST Driver]

I torqued it down to something between 20 and 25nm. 20nm were no problem with a standard bit but just below 25nm the bit started to bend the slotted head of the valve.

Something between 25-28nm is just right.

Keep in mind to manufacture a special tool.

Best regards,
Phil

[shantybeater]

Thanks for the details, I got my specialist to fit the seal with its oil change.

Just a heads up, the seals & tool are on there way to 'althulas' so direct any requests onto him. Thanks again for this Soma, very kind of you to do this especially for free...

[soma]

Great to hear the tool and rings are making their way around to other M owners! Keep it going and stop those leaking valves gentlemen!

[swamper]

if there any left could i have one please

[Althulas]

Hi guys just to update James has sent the seals and tool on but I'm away and unable to collect the parcel intill Friday and will contact people who want one of the seals to forward on or who next inline for the tool after I can get my car in for it's oils change and a few jobs including this one.

Mark

[Althulas]

Got the items today James Cheers if I've followed the thread correctly Sonic is next in line for the tool and o ring kit. If anyone needs just the o ring can they pm me so I can post them on.

[John Wilson]

Just to say, what a brilliant thread this is. Z owners cooperating together to fix a common problem. Thanks to Soma for the inspiration and generosity for initiating this. This is what the site does best and is what will keep it thriving.
John

[Althulas]

I got mine done today along side my inspection I and diff and gearbox oil change. There was a small leak from CPV and the o ring was solid like plastic. I believe Sonic is next in line PM sent.

Thanks again Soma my indie was impressed with your generosity and Pingu write up.

Update kit sent out to Sonic 28.03.12, I believe Swamper is next in line after Sonic

[cemalakcal]

PM me if you still have constant pressure valve O rings kit

[soma]

HI Sonic,
I hope everything is going well with the tool and rings. Have they been forwarded on to the next person in line? There is a gentleman over at Z3Mcoupe.com who lives in Ireland who would like to get a hold of a ring. I told him to have a look at this thread and make a request.
Keep those ring replacements going!!!
cheers< Soma

[pingu]

Info for when the free ones run out:

I have just got some o-rings for my Escort's FIP and they supplied next day for £1.50.

The o-ring for the constant pressure valve is 14.5mmID and 1.5mm cross-section

http://simplybearings.co.uk/shop/p513108/1.5mm+Section+14.5mm+Bore+VITON+Rubber+O-Rings/product_info.html

There is a minimum order quantity of 2 and that will cost you £5.70, but 10 will only cost £6.95.

[soma]

Viton is the real deal...that is a great price too
Whoever has the tool and rings presently, it would be good to get in touch with the next person in line. cheers< Soma

Many thanks again Soma,
