Inlet Manifold Cleaning

[huwb]

I cleaned the "throttle" last night on our 2007 60k 2.0 TDCi - it was not as bad as I had expected but there was a coating of sludge built up on the blade and body. 

 

I have just cleaned the EGR mixer on a 130k Volvo D5 and the 10mm deep coating of soot/carbon/sludge has propmted me to check the Galaxy mixer.  Sadly the "mixer" on mine is integral to the inlet manifold so cleaning requires removal.  I managed to get a gloved finger up inside and scrape out quite a bit of goo that was about  2-5mm thick depending on where I rummaged. 

 

In frustration I have just bought this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110907922480&ssPageName=ADME:L:OC:GB:3160 - safe in the knowledge that it will annoy me by setting the EML!

 

However, I would like to give the engine a fighting chance by cleaning the inlet manifold or maybe for ease just bolt on a replacement (~£200 on Ebay) and clean mine later to sell.  Has anybody done this and do I need to replace umpteen gaskets or remove injectors etc?  It looks fairly simple but the jobs I screw up always do.

 

Thanks, Huw.

While I'm sat at my PC I thought I'd add that EGR delete software is available so that the EML does not appear when the EGR is blanked.  The software changed just tell the ECU not to check EGR operation hence no light.  My blanking plate arrived today and EGR delete is available as a no-cost option with a remap from Shark performance (Peugeot 2.0HDi engine is also used in the Focus): http://www.sharkperformance.co.uk/brands/Ford/Focus/2.0TDCi%20136hp/

 

I'm just not sure I want the extra oomph of a remap as our clutch is probably already on borrowed time due my terrible towing exploits.  To be fair there is adequate performance in it as standard but I do like the idea of not filling the intake with filth and we intend keeping the car for quite a while.  Hmm...

Given the date of the post i guess you have fitted this already. Tis a simple job and as long as the valve is still working I don't think you will get a dash light. Well I didn't on my 1.8.

 

In the end I removed the cooler as well after a strip down for a turbo change. Saves carrying unesssary weight

 

Regular 43mph without any effort

Thanks Gary,  I haven't got around to it yet but it's on my list.  My nuclear option would be removal of DPF, EGR blank and then remapping to suit.  This scares me a little as who knows what MOT emissions checks may be afoot.  There will be no external evidence so it's tempting.

I know there are plenty waiting in the wings to flame but from what I can see so far the EGR is only good for sale and a few thousand miles thereafter. Then the inlet mafifold, oil etc all start to get polluted and the MPG drops. So now you are using more fuel and carrying the weight of an in effective system. More pollution?

 

As for the MOT certainly the current tests do not see any difference, actually no they see things as better cause there is often less smoke. No doubt that will change. As it stands now the egr blanking plate is a very quick install and remove so could be done either side of the mot

That's how I see it too.
