Well, Dan Shane and I pulled it apart this evening (just got back) and 
the cam setup is totally different. I didn't take my camera but it's 
really, really wierd.

It's still SOHC. The intake valves have seperate rockers so there're 3 
lobes per cylinder. The exhaust cam has a forked arm, and all of them 
run on little pushrods in the centre of the ladder, which all fall out 
when you take them off! The tappets are hydraulic. The spark plug wells 
go through the rocker covers and sit between the intake valves.

They're known for eating cams and those little pushrods are well worn on 
this engine, and the left cam definitely needs a re-grind. Chain guides 
show very little wear. Citroen did a ceramic set for them but it's 
stupidly expensive (typical Citroen). I will have to price them up from 
Peugeot. In the mean time we'll just build it up with new original parts 
and be religious about oil changes I think.
