PSA 1.6 8v HDi (DV6C) Full Disassembly

- 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.

Great teardown, those glow plugs came undone quite easily
Very interesting! Many thanks for the upload!
I've got one that has done 410 000km now. Leaking oil from somewhere around the oil filter housing or head gasket. So this helped a lot!
Seems to be pretty easy to work on overall. Hope mine has another 400k after som TLC.
Interesting. These are quite a complicated engine.
I recently tore down the 1KR-FE engine from my Yaris. The headgasket failed in the summer and as the weather got cold it just wouldn't start anymore at 240,000 miles. It was leaking coolant into Cylinder No. 3. Put a used engine in the car as it was the cheapest option. Tore down the old one. It actually wasn't as poorly as I thought it was but it would have definitely needed a hone in the bores and maybe slightly oversized pistons if I wanted to put it back into service. Oddly enough the top end, timing and bottom end was all absolutely immaculate. Shame really.
Merry Christmas mate.
The core of the engine is quite straightforward its a single cam 8 valve design, simpler than the earlier 1.6 16v engine. The ancillaries add a bit to the complexity but generally simple enough.
Your Yaris engine done well, but they are a good solid engine. How did you find sourcing oversized pistons were they available? I know there are plenty of videos of old american V8s getting that sort of treatment but its expensive work, not sure if manufacturers even supply oversized parts anymore.
Thanks and merry christmas and a happy new year to you.
@@peugeotCitroen2CV I suppose those wankers at PSA probably took an older engine design and just kept adding bits onto it over the years like Ford did with their old 1.8 diesel.
Yeah - considering they are made for small run around cars and made to a budget mine has commuted endless miles and been all over Europe on road trips with a fully loaded car. You know I hadn't actually checked for sure they were available but I saw some video from Pakistan where some mechanics rebuild the exact same engine with oversized pistons as the bores were worn. Either way - £240 delivered for an engine with 55,000 miles. Another £200 in assorted parts including a clutch kit to install it. I'd call that a good days work for another 100,000 miles out of the car.
@@zoidberg444 i think the 1.6 was a new design when it came out, their 2.0 engine is an evolution of the old XUD but the 1.6 was co developed with ford hence why it ended up in so many of their subsidiaries at the time.
As diesels go i would rate HDi diesels as some of the best, certainly better than any clean sheet designs to come out since 2010 like fords wet belted eco blue diesels, the JLR ingenium or mazdas diesels. Of course thats if you want a diesel, i still like my C4 as it has provided great service the past year going back and fourth to uni, obviously into the future with tightening legislations it seems that there will likely be a switch to petrol or some form of electric/hybrid propulsion. Although the C4 gets 50mpg at the worst of times, mid 60's if driven with care.
Thats really not bad at all to get more driving out of the yaris. My aunt had a red MK1 yaris it went well over 200k miles she was driving all over ireland in it, i remember her bringing it to me because it was overheating. I asked when it was last serviced, she said that time you did it. Which was the time i did the video on it 5 years previously haha. A commendable effort.
Compared to previous version of the 1.6 diesel the dv6fc is simplified but a reliable engine.
Hello sir
Evri morning on cold weather i have a noise coming from timing belt area
After 10 mini on idling the noisy stop
I suspected the high pressure fuel pump
Its same engine.
Wather pump and timing belt been done 1 year a go
Any ideas from where is coming the noise?
Thank you sir
Wow, what a good job. To put it back together, how do you not forget any connectors, sensors, screws, nuts and hoses?
Hi there, thanks for the comment.
I was not putting this back together but for jobs were you are lots and lots of pictures, even record videos speaking to the camera as notes to help reassembly, my uncle has a mushroom farm so i get plastic punnets for mushrooms to keep bolts in, but the boxes from a takeaway or tupperware boxes do the job, labels and post its help. Hoses and wiring looms generally only go in one way, looms although they flex tend to have a bit of shape memory and the wires are normally a set length with specifically shaped plugs. I did have to change an engine for a K12 micra the replacement was more just the engine with nothing attached and the loom and ancillaries had to get swapped that was the way i did it. Everyone has their own ways to organise things to ensure they all go back together.
Of more importance though is knowing what gaskets need to be replaced for reassembly, and the proper tightening sequence and torque spec for bolts, i am not sure if the head bolts or big end bolts are reusable for this engine, it would not surprise me if they are torque to yeild and would need to be replaced.
