Primary Chain Oil Spray
The original design of the engine did not provide a direct oil spray onto the primary chain. This may have contributed to the early wear of chains. While modern are significantly more durable than those originally fitted, it is possible to add the spray that Citroen fitted to all later engines and required on reconditioning. In order to locate the spray correctly, the following jig is required.

The original factory hole was 0.5mm. Citroen specifies 1.0mm in this jig, possibly because of the care needed with the smaller drill.
(Does anyone have one of these jigs to rent?) Brucem 23:42, 18 August 2008 (UTC)
