As an owner of a 1.6 HDi in our 207 SW that intends to keep it for some time I decided to look into the lubrication issues of this engine in great detail in order to maintain the engine to the highest possible standard and avoid potential problems.
This engine is used in a number of cars including Citroes, Ford, Volvo and even Mazda in some markets. All have complained about the sensitive lubrication on this engine and the costly consequences if not maintained properly.
I recently changed the oil and filter on my car which I now do every 5000km and for good reason.
The last service was done by my Peugeot dealer 5000km ago and when I drained the oil and looked at the filter element i was suprised how bad the oil looked and smelled. Since replacing the oil / servicing myself the engine feels more free revving, quiter and the economy has improved. The question is what the did dealer put in ? I can not prove it but it did not seem to be the good stuff. On that servcie they also overfilled the oil and I luckily spotted that staright away. Idiots !
The 1.6 HDi engine oil lubrication can get clogged up if you do not stick to correct service intervals, procedures and use the correct oil which is TOTAL Ineo Ecs 5W-30 fully synthetic.
There have been a lot of Turbo failures on early versions and still reports of Turbo problems on later engines. This is due to the oil degrading to the point where it starts to congeal blocking the oil feed pipes and carbonizing the EGR valve and Turbo pressure release valve [ dump valve ] as well as blocking up the FAP [ DPF ] exhaust filter. The Oil pump has a gauze on it that really needs to be cleaned out every 80,000km along with the gauze in the oil feed pipe to the turbo. These are the main clogging points.
So why does the recommended fully synthetic oil de grade and may clog up ?
The 1.6 HDi can get very hot and the turbo itself degrades the oil from very high temperatures achieved at the shaft and seals. Over time any oil, no matter how good and expensive de grades where its lubrication properties are no where near to what they were when new. Its mainly contaminants from the engine and carbon which enters the oil via blow by from the piston rings and linings. This varies a lot from engine to engine so for some a more frequent oil and filter change is advisable. A perfect example of high wear is a car that is used on short city runs day in and day out. If you fall in this catergory you should be thinking about changing the oil and filter twice as often.
Dealers have a lot to fit in and do not alwys drain the old oil properly allowing some of the contaminated old oil to mix in with the new oil which then de grades much faster.
Using an oil which is not an emission system recommended type is asking for trouble. On this engine a low saps oil is a must. Below is an example of the EGR valve fouling after 80,000km with a low SAPS [ Recommemded oil ] and conventional oil;
Some dearlers use Generic oils which are not designed for the recommended service intervals. If you have bought a car used that is outside warranty where has the previous owner been servicing the car ? What oil was used ?
The 1.6 HDi oil filter: Its an element cartridge type that is contained in a plastic housing. It is unusual as it has a small nipple with a seal at one end that slots into the corresponding hole in the mounting plate on the engine. You must slot this in before putting on the cap. When you unscrew the filter, the element comes out with the cap as it is retained in place so to the untrained it looks as if you just have to slot it back into the cap and then refit. Wrong ! If you do this you are not filtering the oil !
Correct oil change procedure for the 1.6 HDi;
1] Make sure that the engine is at normal operating temperature
2] Remove dipstick and oil filler cap
3] Car has to be on level ground, not jacked at the front.
4] Unscrew oil filter cap [ 27mm socket ] put a rag underneath the oil filter to catch small residue when open.
5] Unscrew sump plug and drain oil into suitable container / pan
6] Leave it to drain completley. Minimum of 15 minutes until no more drops
7] Renew filter element as described above including the seal on the cap. Run a bit of oil over the seal before refitting.
8] Clean the sump plug and replace the washer. Do not overtighten when refitting. Clean the area with a clean rag to remove any oil residue from the sump and plug hole aperture
9] Using the correct oil [ TOTAL Ineo Ecs 5W-30 ] slowly fill checking the dipstick on a regular basis. DO NOT fill to full mark. Fill to approx 90% as this will avoid oil going through the CCV pipe into the intake and turbo in the first 50kms. After 50kms top up slowly to just below the full mark.
10] Optional but highly recommended: Add Wynns Formula Gold diesel into a full tank of fuel. I use this and it works extremley well and does exactly what is says on the box. Reduces carbon, cleans injectors, increases performance and economy and its Cerium based like the Eolys fluid so its compatible with the FAP [ DPF Filter ]
11] repeat above every 5000kms and you will have an engine that should be trouble free.

Another weak spot on this engine is the PCV valve on the front rocker cover. It is unfortunatley integrated in the rocker cover and I would recommend changing this every 50,000km as the spring actuator valve is not the best design. The rocker cover with the gasket is around $120 and very simple to replace.
Most depollution faults are due to:
1] Clogged fuel filter
2] Clogged EGR valve
3] Faulty Air doser [ Throttle body ] Oil contamination through intake or leaking tubo seals
4] Faulty air sensor on the left hand side of the air doser.
5] Regeneration fault
6] Clogged FAP filter
7] Faulty PCV valve on rocker cover as explained above.
To conclude a well mainatined engine should not have any problems. Most of the above happens due to poor maintenance, bad oil and constant short journeys without more frequent oil changes.
This is not to put you off a 1.6 HDi just to make you aware of potential problems and issues and help maintain a great engine to its full potential.
Prevention is always better than a cure.....
