Intake manifold carbon cleaning

[matteo]

Hi guys,

Seems like I have to have my intake manifold carbon cleaned, possibly an EGR blank done after that. Rough idling and excess smoke when engine warms up. Strange though, it doesn't happen with every drive.

Can anyone recommend a mechanic or somewhere where I can attend to this in Cape Town? I've seen some guys offering a "non-invasive" clean, but I'm sceptical. Does anyone have experience wth this? Also seems like it would be a massive job to remove the manifold and get it cleaned...?

Any advice appreciated.

Cheers.

Good day

It is not too difficult to do this job. Just takes time.
I did mine a few months ago. used pressure washer and oven cleaner.
Looks like new now.
For EGR blank use a piece of stainless steel plate and put it on inlet manifold side.
5 min job for fitting.

Hi,

I am planning to do my Gen 4 soon as well. I service my car with Jacques Norval and when I was there a few weeks back he had just completed an intake manifold and intercooler clean on a clients 2.5 triton. Give him a shout.

Cheers

Hi Martyn, could you please give me a guide on how you blanked off the EGR?

Interesting subject ---the carbon cleaning of the inlet manifold.
Where are the carbon deposits originating ? Diesel 500 ppm , 50 ppm or even 10 ppm ?
Why does the turbo not suffer the same carbon problem on both ends (exhaust side and boost side) ???
Sorry, I am not a specialist but it does not make sense to me , So please put me on the right path....
