What should the timing be on a 1972 Citroen DS?

What should the timing be on a 1972 Citroen DS?

On my 1972 DS, the timing should be set at 12 degrees BTDC. This can be accomplished by inserting a 6mm pin into the timing hole on the flywheel, and rotating the engine until the pin engages with the hole in the flywheel.

Where is the oil filter on a Citroen DS?

Changing the oil on a DS is slightly more involved than on a normal car. The oil filter is an internal unit held in place behind a screen and a plate, which in turn are behind a cover plate on the bottom of the sump.

What causes the injectors on a Citroen DS to leak?

After speaking to Stuart at Brodie Engineering, I remembered that there was a known fault with certain types of injectors fitted to the DS and SM which causes them to leak. Injectors with the part number 0 280 150 003 are bad. They were replaced with Bosch injectors 0 280 150 043.

How do you test a Citroen DS engine?

This can be accomplished by inserting a 6mm pin into the timing hole on the flywheel, and rotating the engine until the pin engages with the hole in the flywheel. This is the correct firing point, so once you have this you need to turn the ignition on (dontstart it!!) and connect a test lamp between the ignition condensor and the coil.

What was the pressure in a Citroen DS 21?

The central part of the hydraulic system was the high pressure reservoir, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the brakes, and the other ran the other hydraulic systems.

Where can I buy a 1972 Citroen DS21?

This DS21 is sold with restoration records and a clean Italian title in the friend’s name. All paint and bodywork were reportedly refinished as part of the restoration and rusty panels were removed and replaced with fresh metal.
