Free Fix for Constant Pressure Valve

Post by 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):
http://www.mcmaster.com/#viton-fluoroel ... gs/=etco9u

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

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.

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. :D .

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? :lol:

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?

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.

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...

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

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!!!

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/p51310 ... _info.html

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

Hi Soma,
Yes I have the kit and will forward to your Irish friend if he wants to give me his details.
I'm not sure who's next so if someone wants to get the kit I'll be happy to forward on.

I have just given the tool I made to DaveP over on the coupe forum to use and said he could pass it on when he finished with it. No o'rings though as I bought a complete new valve when I did mine.
