Taking apart a DV6C engine to see what was causing it to knock badly. This engine came from my friend's Citroën Berlingo. The engine had been fine, but it was remapped a week before the noise started, so that is what this has been attributed to, as these engines are generally very reliable. This is the first one out of the many that power vehicles owned by friends or relatives that has done this.

In the end, the engine suffered a spun bearing on the big end nearest to the timing belt. It would have needed a set of bearings, a conrod, and a crankshaft.

It worked out handier to buy a scrap C4 Picasso with a good engine than to consider rebuilding this one.

My friend left this engine with me after another mechanic did the engine swap for him. I was interested to see what caused this engine's noise, but also wanted the opportunity to fully disassemble one of these engines. My friend is able to sell the ancillaries, and I got to keep a jar of all the nuts and bolts removed from this engine, which can be very handy when working on cars to have spare.

This is not so much a definitive guide on how to take one of these engines apart. I'm not sure I went about the process in the most efficient manner, and certainly did not follow any specific sequences for untightening bolts for the camshaft carrier or head, which would be important to follow if rebuilding the engine. However, it should hopefully show where everything is and what inside these DV6C engines looks like.

If you want to get the proper torque specs and disassembly guides for one of these engines, a Haynes manual is a good point of reference. Alternatively, ServiceBox, which is PSA's online portal for parts diagrams and official workshop guides, will have the required information.
