Rocker cover gasket replacement - Peugeot 406 2.0 HDi 110

How to remove the rocker cover on a 2.0 HDi engine and replace the rocker cover gasket.
The engine is the DW10ATED (110) or DW10TD (90) 2.0 HDi engine fitted to a 406, and a load of other PSA stuff.
I noticed a bit of mucky oil mess round the back of the engine as i like to keep it clean.
Thanks to a guide a fellow 406oc member captain jack made i was able to get the rocker cover gasket changed. Hopefully this will keep the top of the engine clean, i dont think it was a serious leak as i never noticed a change on the dipstick. There is a possibility that the air doser on these 110s can leak oil but i dont think mine is, and i cant see any oil line going to it, so any comments on what an air doser does or how it can leak oil are welcome.
I used the spare engine i have from the spare parts 406 to show how to remove the upper timing belt cover, this would have been a very handy thing to have had when i was changing the timing belt. Hopefully you this view will help you find the bolts holding the cover in, there may be a bolt round the bulkhead side of the engine as i show in the video but on both the spare engine and engine in my car the bolt is missing.
I reused the clip holding the crankshaft breather pipe to the rocker cover, the clips used are not the easiest to click back into place but with a good pair of pliers (i used wire cutters) and some patience it is possible to get it back on, if your having trouble getting it to go back on just throw it away and use a conventional jubilee clip.

Brillant video mate , I watched your timing belt video about 100 times and now can successfully change timing belts. This is very helpful too , I’m off now to buy a gasket 😅

Hi, I like the engine cover holders, did you make them by yourself?
Nice video

[@peugeotCitroen2CV]

Hi there
Its been quite some time since i got them, think someone at the time was selling them on ebay at the time
They are just mechanical vibation damping mounts, i think m6 or m5 thread with a dome nut and some washers. Any fasteners company or ebay should still have them.
although something like this

[@abdellahabdelah7271]

Can you please tell what is that orange connector for? The one connected on diesel pompe

[@lofturhjalmarsson295]

so wiping engine contact area is to remove dirt from outside of gasket limit , not to make it non slippery for new gasket so it will stay upright

[@peugeotCitroen2CV]

Loftur Hjalmarsson
Primarily to remove dirt or any remnants of the old gasket to give the new gasket a clean surface to seal against.

[@markol.8173]

Have you ever cleaned or changed the sealing of the high pressure fuel pump regulator? My 406 HDi' s engine sometimes running a few seconds after turn off and a fail code is P0230. Lights: Antipollution failt and engine failt.

[@peugeotCitroen2CV]

Hi, no its not something i ever had any issues with on this car.

Hi
my clima compressor is broken but l do not use it since l have mounted bigger intercooler
l need help to find pkk belt for my 2002 20hdi rhw without ac compressor
could you help?
any clue?

[@medioman74]

i spotted the tiny puddle of diesel or oil by the right most injector. i've got the same on my engine. is that because of the rocker cover gasket?

[@peugeotCitroen2CV]

There is a pool of oil under the left most injector (left being the one closest to the timing belt). That happened because of oil spills when filling up the oil and it being awkward to clean out. However, ​these valleys did end up with oil in them when the rocker cover was leaking.

[@kamenivanov]

Thanks for that !

anyone guys help me um looking for this engine Peugeot 406 diesel , i cant get one here in africa Botswana , i tried buying online but cheated in return

[@peugeotCitroen2CV]

It is a DW10ATED 2.0 HDi, they are still an easy engine to get here. It might be cheaper to try and get a full car rather than the engine. Although shipping is the concern.
