Oil catch can time.

[MattBLancs]

So , mixed finding regarding the oil catch can , so say its illegal and will fail the mot, some say different , NOW at a cross road again.

Hi, sorry no response from me recently, been busy with work.

My understanding is a catch can routed to vent to atmosphere is a no no (even if it has a little filter on its vent connection), but piped back into the intake again is fine (as effectively an improved separator over standard. It's the unburnt hydrocarbons venting to atmosphere that's the issue.

When i took the old turbo off today there was no gasket from manifold to turbo, the dpf side of the turbo is very sooty , the turbine on the new one is so smoothe compared to the old one. Im waiting new oil feed pipe as i see they should be changed aswell even though the one on it is only a year old. Oh well.

Im now thinking of getting a 1.4hdi 206 ? Am i mad ?

[MattBLancs]

Morning,

I can't recall if there was a gasket at that point or just metal to metal (will dig see if I took a photo) I do remember the 4 weird nuts in this joint - small heads and like a helicoil inside the nut! Very odd.


No experience of the 1.4 HDi, I believe it doesn't seem to suffer the loosening injector clamp nuts like it's bigger brother (the 1.6 is directly related) 1.4: 8valve, Vs (early) 1.6: 16v. There is a 16v 1.4 HDi but weirdly only the Citroen C3 got it. Injector problems in this unusual variant I've read.

No 1.4 HDi 206 had a particulate filter, so there's a plus.

Think is 70bhp as standard (71?). I have had experience of the older 1.9 DW8 non turbo diesel in a 206. These are similar power output (68?). My dad had his for about a decade and I drove it a few times including a bit of towing. I'm no racer but have to say I couldn't live with driving the DW8 daily. Frustratingly slow. Very odd really it was almost like it had a massive flywheel - reluctant to increase the revs quickly, so painful to try and accelerate at low speeds. But then in 5th on the motorway (when road speed change= small engine speed change) it was fine. Unless it was a full car, 5 up the lack of power was obvious again.

Anyway, the 1.4 HDi lacks an intercooler as standard and various reports online of good power increases with intercooler and remapping.


Not sure if the 1.4 HDi also has a solid flywheel too?

I think this pipe change is on the basis of it being full of burnt on oil crud (and hence a risk to turbo bearing oil starvation, again) if is only year old I'd consider refitting it - it's taken years to accumulate inside, so at 1 year should be relatively clean I'd think. The counter argument is that everything I've read about DV6 turbo replacement is you "have to" replace this pipe with turbo so would be a get out clause on any warranty if didn't change it.

Cheers Matt, ive 5 yr warrenty on the new turbo so i got the new pipe to help the warrenty as we all know what making a claim on these can be like, ive had a 206sw 1.4hdi nice little car but dash lights would come on a lot then it did in the end give up it will to live, on the day it went to the breakers it started up then cut out again then i found out it was running on 2 glow plugs as 2 were broken and just hanging on the loom , thanks to the previous owner. My old turbo i took it a part see photos, the spindle was worn , and there was a shard of metal inside it . The shiny side the air intake was shiny on one edge and normal on the other so the blades have been rubbing one side hence a worn spindle. The banjo bolt with the tiny filter was clean when i removed the oil feed pipe very pleased with that , new one should be here tuesday fingers crossed so new oil feed pipe to a new turbo , plus I've a new rocker cover to.

Something was going wrong with the old turbo and taking it apart gives the answers.

[MattBLancs]

on the day it went to the breakers it started up then cut out again then i found out it was running on 2 glow plugs as 2 were broken and just hanging on the loom , thanks to the previous owner.

I tested the glow plugs on my wife's 206 when I made a start on its turbo replacement - all four defunct. It started and ran (and regened) fine, I don't think HDi really have much need for the glow plugs. I decided to replace them anyway, and so regretted that decision as 2 sheared off when I attempted to remove them. That was trigger for engine out, head off and give a more thorough clean as part of turbo replacement. There was thick black everywhere, all oil system pretty grim and intake / head also full of crud from EGR+ (faulty, split diaphragm) PCV system. One injector very reluctant to come out (just early signs of injector seal failing - hard black crud stuck it inside it's tube in the head. A few hours to literally persuade it out fraction of a mm at a time. Talk about a job that kept growing!

Anyway, good work on catching the turbo early! Interesting it's been rubbing the casing, I thought by the time it was making contact like that it was right on the very cusp of catastrophic failure, so I'd take that as a massive bonus (verses dealing with an engine that's just ingested bits of turbo, the tale of woe I described is still preferable I'd say!)

Nothing like the broken glow plug job ! Did my picasso 2.0hdi plugs when i had it 3 came out good one didn't want to play ball but using the plug removal set does make things a bit easier,To be honest once the 206cc is all back together i "might" sell it , but i know when i drive it i will change from might to might not..... its nice to drive I've a wind deflector to try which i haven't used yet

[Huskyxantia]

Correct me if im wrong are these settings correct for the oil feed pipe banjo bolts for the 206cc 1.6hdi.
Oil supply pipe to turbocharger: 30Nm
Oil return pipe to sump (top section): 10Nm

Not sure but can check the (307) Haynes manual I have that covers the 1.6 HDi (should make no difference it being in a 206 instead)

Will try and get it done in the morning (long day today, alarm was 04:50 and am feeling it now!)

Cheers matt, have a good sleep

Morning,

From Haynes 4147 (307 2001 to 2008) owners workshop manual:

Turbocharger oil feed pipe banjo bolts:
1.6 litre engine 30Nm / 20 lbf.ft

Only one figure presumed applicable for both ends of the pipe.

The 2.0 DOHC engine does list:
Turbocharger oil feed pipe banjo bolts:
Engine pipe to cylinder block 40 Nm/ 30 lbf.ft
All other connections 25 Nm / 18 lbf.ft

PS I had trouble getting this connection oil tight. I tried thicker copper washers and then tempered them (heat with blow lamp till glowing red then allowed to cool)

Matt

[Huskyxantia]

Matt your right about them washers, i completed the job everything back as it should be started the car let it run topped up the coolant then blead the system moved the car back w fee feet ... nice oil puddle .. laid a rag down after turning the car off then screamed in my head because the the parts you have to do and move to get the that bottom banjo bolt as my access room is as tight as a natts chuff, anyway just now i sorted it the washers were the wrong way round swapped them tighten the bolt quickly ran the car for 10 seconds and this time no leak !

Just have to pop the dpf back to its postion clamp it up and refitted the rad and pipes top up the coolant and bleed the system again ... jobs done new turbo new oild feed pipe new rocker cover plus thicker o ring on the pipe that goes into the rocker cover. Cars who needs em.

[MattBLancs]

Oh yes know what you mean, the one on the block is a pain when you find it's weeping. Soooo buried behind the heat shield, behind the DPF, behind the front heat shield, will too little gaps to get it out as the radiator is so close. What a pain.


Not sure if you have had the pleasure of it yet, but gearbox isn't much fun to remove - top few bolts to the sump are really buried too.

And the starter motor , right on the back of the block not a very fun job either!

Taking the engine out was much less involved than I imagined it would be. And £35 for an engine stand, £80 for a crane (both new, cheap rubbish off eBay, second hand choices available cheaper but nothing local at the time for me) made the top end , clean up etc a much more pleasant job! First time I have taken an engine out on my own - sense of satisfaction when back in and restarted first time= fantastic!

Matt

[Huskyxantia]

Yes and also that feeling of knowing how much money you save doing stuff yourself is another fav feeling i like after each car repair i do. I used to hire engine hoists 20+ yrs back £20 for the day they make the job so much easier, that feeling hearing the engine burst into life after tinkering is brilliant.

[Huskyxantia]

So after spending time yesterday sorting a roof out bird gaurds and taking my lovely wife out this morning this afternoon was my time so i completed the job on my 206cc took it for a run and was pleased with how it felt got to 70mph in a blink of an eye no smoke no nagging mil light and i noticed the gauges read slightly lower than before .
A massive big thank you to Matt for your help very much appreciated
Next job is to line up the rear passenger side window as its slightly out 3mm ,and it let in some rain but happy the car is now back on the road.
