Right well im hazzarding a guess that mine will defo need doing as mine just just clocked 120k. S3Alex - this walnut blasting is it something i could do or will it cost more in gear than get a garage to do it?? i am very competent with engines/cars as i build classic fast road and race engines for minis and midgets :)

USP Motorsports sell a relatively cheap DIY kit,but the real deal is having it properly done,and I believe for around £200 or less.

Best to approach them and see what they can do.
 
Anyone know of anyone in the Southampton area that offers the de-coke service? What's the proper terminology for this service anyway?
I'm pretty sure my PCV has gone as well, so I might replace that at the same time. Although, I could probably do that myself.

If you're talking about their intake valve cleaning product,it's something that needs to be injected into the intake,after the MAF,and is supposed to break up carbon deposits on the valves.
Personally,I have no knowledge of the product,and there's very little in the way of feedback on the net,but I can't see how a spray is going to deal with hard,burnt-in deposits on the valves.

The other product they have is introduced via the injectors,and won't work on direct injection systems.

I know which I'm happy with.

I've read else where that it's a good idea to replace the N80 Evaporative Emissions Control Valve as well. Do you guys agree? If so, anyone got the part number for the latest compatible revision?
 
just my humble opinion but if you want your carbon gone there is only one effective way of doing it...elbow grease every 20K for me



 
Well just in case anyone else is facing the same issue...

I replaced my Positive Crankcase Ventilation (PVC) valve tonight, which not only resolved an issue where the car was idling rough at 800-900RPM and hunting up to around 1300RPM, but it restored a fair bit of boost, improved engine response and smoothed out performance when letting my foot off the throttle. Very happy indeed. Especially as it was a five minute job for anyone who can turn a screwdriver!

So anyways, the handy info I have are the current part numbers, as supplied to me by Southampton TPS (a.k.a The Trade Parts Specialists). These guys are the most professional supplier of OEM parts I've dealt with. Many of the garages/workshops in Southampton get their parts from these guys. That's how I found out about them. Anyway, enough friendly promotion. Here are those part numbers:

PCV valve cover assembly: 06F 129 101 P = £32.24 inc VAT

PCV valve cover gasket: 06F 103 483 E = £16.78 inc VAT

PCV valve cover to turbo hose: 06F 103 215 B

PCV tube to turbo metal gasket: 06F 145 757 F

I actually only bought and replaced the PCV valve cover assembly and the PCV valve cover gasket (always best practice to replace gaskets and seals when replacing the associated parts), which came to less than £57 inc VAT. But if I remember correctly, all four parts would've come in at around £80. Considering other older revisions of the PCV alone on eBay were shifting for £45 inc postage, I'd say going to Southampton TPS was a much better choice. I hear they're pretty good when it comes to returning parts you might've bought that were not correct for your car.

Result!

Hope this info helps someone.

This might be worth considering. I had this done recently at my last service, only around £65 to have it done. Definetely noticed a difference aftter in relation to general running and idling of the car. A lot smoother afterwards.

Relatively an easy fix too.

Would be good to see the insides of the inlet valves after the chemical clean to compare against the walnut blasting cleaning.

I was wondering where you had this done?
Trying to decide whether to remove my manifold or if there's someone I can trust I may give this a try.

Im going to to TPS tomorrow, as heard good thing about them to!

Did you not fancy the PCV delete kit instead? Waiting on mine, as im sure its not right.

Im trying to get a friend of mine with a specialist BMW garage to get a walnut blasting machine. Well worth it, and great results. Though seeimg the above from just hard work looks good :D
 
The problem with all of these is that they don't completely stop coking.

We'll find out if my VTA breather system does what it should do soon enough,and also the breather catch tank is being cleaned out tomorrow or Wednesday,so that will give an idea of what the normal PCV delete and catch can doesn't catch.

Alex, Does WMI not have this effect?? does the mix not effectively steam clean the internals and ofcourse the inlets as they are the entry point into the chamber or is the carbon just too hard to move without stronger solutions?

No...all of those nasty pics of mine(and here's a reminder)....




Are with WMI running.

It's possible that with port injected WMI,it may be effective,but I can't see it myself,as the system simply doesn't run all of the time.

For those that like dirty pictures....

Here's around 2 month's worth of what would have gone through the inlet valves from the cam and crank breathers.....








That's about 500mls of gunk.

^^^^^

That's pretty frightening!

I already have the Revo PCV Revamp fitted, but I reckon I may need to also invest in some sort of catch can to try and catch some of this gunk...

A catch can and PCV delete will get some of this as evidenced by what collects in the can but it won't get all of it due to the breathers at the rear of the cam cover.
 
That picture of your valves Alex had they been cleaned and then had the wmi fitted and that was the build up upon inspection? or was the wmi fitted with already dirty valves.

Im eagerly awaiting pictures of your valves since the new cam cover has been fitted with the rear pcv delete and catch can.

Hi.....

The pictures were all with WMI fitted.

Basically I don't think WMI makes any real difference,and a conventional catch can only gets some of the gunk.

I'm pretty sure I've got the answer with the VTA breather system,but when the engine comes out shortly,we'll find out.
