As long as you remove the MAP sensor and dry it properly, should be fine.

And if your worried about removing the inlet manifold, another how-to in addition to Arctic's

I should of said that I tried using a hose but it was nowhere near powerful enough to blast out all the ****, and my car hasn't exploded since.

As Above remove the MAP clean that with carb cleaner quick burst dont soak it, then jet wash Manifold through every single hole even the little one where the MAP sensor fits if you do not have a jet cleaner at home see if you can get to a jet wash at a garage and use that some have hot jet washes even better. :xmas-smiley-029:

There is really only one proper way to clean the inlet manifold as far as I am concerned.

I paid a local engineering company £20.

They sprayed the inside with a high pressure heated mix of kerosene and steam.

The inside is literally how it came from the factory. Shiney and looks brand new. Not a speck of black crud anywhere.

However, it actually made no difference at all !!

Worth getting this done by someone else with the proper stuff. The stuff inside will be seriously carciogenic/toxic, not to mention the mess it makes. Just not worth the hassle.

The EGR on the other hand....... ! Well worth doing.

I am sure it must have made a difference i know how i would like my manifold to be inside, don't forget some of the manifolds can be really bad which in turn make the engine bore close up as below this was a members manifold i changed for them

Well thats the thing I thought about...

On a turbo engine, it will pressurise the manifold to a set pressure.

Should the airflow be slightly restricted, all thats going to happen is that the air will flow faster through the manifold, but the same volume of air will still be getting through surely?

Unless of course is so badly restricted there is backpressure to the turbo....

Well thats how I was thinking anyway...

Not sure on the exact physics principles!!

Default Diesel Manifold Gunk (what's yours like ) ?

I cleaned out four manifolds this weekend starting on a Friday by removing the EGR, MAP sensors, and rubber seals.

Then scrapped out as much gunk as i could from each manifold, then it was sprayed with oven cleaner and engine degreaser they ere then left over night ready to finish cleaning out on the Saturday.

There must lots of owners running around with clogged up manifolds stopping the engine from breathing proper.

All have differing amounts of gunk in them some that just trickles out when scrapped off the internal ports,1

5

A lot of owners add bypass EGR thinking that will help, but in fact all it is doing is hiding the trouble in the manifold that as already occurred, and needs dealing with for the engine to breath properly.

6

7

8

It took me 5 hours to scrape out all the gunk from these manifolds, even then there is still quite a bit that is hard to reach which the oven cleaner and engine degreaser soaking over night will loosen, ready for the jet washing of the manifolds.

Some of the tools i use and always wear thick rubber gloves this muck get everywhere, it will ruin your clothes if you get it on them.

10

Jet washing took place though out Saturday which took another 5-6hrs.

12

13

Ready to have the clean EGR and MAP sensors fitted, some will have an original gutted EGR others just the EGR not touched.
14

15

First one sorted ready to befitted on a local car at the Nano in Oct 3rd
16

All four re-built and also ready for the meet.

18

I must say i was pleased with the out come

If you are going to the Nano meet and would like a swap out of your manifold EGR, MAP sensor then drop me a PM Arctic.
