Tin top help
Hi fellas,
I have an R plate 406 2.1TD Estate the engine before the HDI ones and i was giving it a once over this afternoon, checking pads, disks, wheel bearings
etc.
Had a gander under the bonnet and have a few questions i wouldnt mind knowing the answers to!
 
engine labels sml
In the above picture
What is number 1?.... my guess is oil pump???
What is number 2?...... my guess is some form of air mass sensor etc???? - And what can i clean it with, i took it out and its caked in oil.
What is number 3?......My guess is fuel filter housing???
Why is number 4 full of oil sludge?....My guess is i dont have one!
Number 5..... I have air in one of the rigid clear fuel pipes and it moves along when i pump the rubber bellow in the top left corner of the picture.
How do i rid the line of the air? when i pump it, it just moves along and the comes back down the pipe.
Close up of oily sludge (no water contamination just oil)
 
inlet sludge
Number 6, i have oil weeping out around all 4 of the ends of the black plastic 'manifold' that sits down the back of the engine.
I know,I know, i ought to buy a haynes!!!!!!!!!

1. Power steering pump.
2. Not an air mass senser anyway, it's a mechanical injection.
3. Fuel filter.
4. It's the air intake, after the turbo. It's probably full of oily sludge as the turbo bearings are weeping, or the engine is breathing a
little. I would assume that as it's an "R" plate it's done a few miles, and this engine was known to consume a bit of oil as
well.
5. The air is in the top of the filter and will not do much harm there. I cn't remeber for sure, but if you turn the canister upside down is
there a drain plug that you can use as a bleed?
6. The manifold runners are sealed with rubber rings with steel bands round, as the rubbers perish air can escape, and it's oily because of the
above reasons.
DO NOT PUT ON KNOB OR BOLLOCKS!

What is number 1?.... my guess is oil pump??? ---------Power steering pump
What is number 2?...... my guess is some form of air mass sensor etc???? - And what can i clean it with, i took it out and its caked in
oil.---------Leave it alone. If it aint broke DON'T fix it.
What is number 3?......My guess is fuel filter housing???---------Correct.
Why is number 4 full of oil sludge?....My guess is i dont have one!--------------From the turbo charger, see also 6 below.
Number 5..... I have air in one of the rigid clear fuel pipes and it moves along when i pump the rubber bellow in the top left corner of the picture.
How do i rid the line of the air? when i pump it, it just moves along and the comes back down the pipe. ------------DON'T worry about it it just
helps to tell you if you've actually got fuel in it and its flowing.

engine.------Again don't worry Citreons, Renaults & Puegeots leak oil for a hobby and yours looks quite clean. it come from the oil in the
Turbo charged air being pushed into the engine.

The sludge in the inlet manifold is far more likely from the EGR (Exhaust Gas Recirculation) than from the turbo oil seals. All the older diesel
engines get choked up with this muck.

EDITED*
Thanks Fellas,
Is it likely to cause problems if i dont clean out this oily sludge?
Or should i rephrase that..........
Would it be beneficial to clean it out!
Jolly, I occasionally have a problem with it starting, maybe once a month it wont start, turns over fine but needs maybe upto 5 cranking sessions to
get it going, could this be due to the air in the fuel?
Here is the bleed screw for the fuel........i think!

If you start cleaning it out, make sure that you clean all of it out or else big lumps will start dropping in the engine, personally, I wouldn't
bother.
Is it puffing out white smoke while you have to crank it over? If yes then I'd check the glow plugs as this is a sign of unburnt diesel. If
there is no white smoke, then you could try bleeding it, but I'd be inclined to check the glow plug wiring first and check the controller as
well.

puffing out white smoke when i am cranking? or on start up after cranking?
Dont think its glow plugs as on the few frosty mornings that we have had in the last few months it's started first time.
