1.6 HDi turbo oil feed pipe - failure modes?

[MattBLancs]

Previously ruled out back with crank down, now back in as contender.

Bit near the heat shield for my liking, will have to tie it out the way I think.

[MattBLancs]

That certainly does not feel correct. Real close to exhaust manifold. Loads of spare length.

Hmmm

[MattBLancs]

Looks like I have that band clamp in wrong position, I remember previously that it fouls the heat shield unless it's just right. Will adjust that on the car later.

There's no alignment marks for DPF to catalyst halves, so have tried to put in the correct place, but can see that coming back to haunt me in a bit....

And there's that misalignment come to fruition.

Band clamp was about 90° out, easily adjusted round

Heat shield, pressure washer not really making a dent on the muck ... [attachment=0]16725724288374523163549576320626.jpg[/attachment]

2 minutes with Savers Cream Cleaner and a bit of old sock

This is the same connection on a 1.6 petrol turbo

Here is a cutaway of the original fittings:



This is the replacement that I have ordered:



It would be only a bit irritating except for the 4 hours labour to change the part.

To make the design even better, the factory fitted a little heat shield, but instead of putting it between the turbo body and the pipe, they put it on the other side of the pipe, so that heat is reflected back onto it from what would have been the cool side.

Did you manage to get the Kinugawa flexi fitted? If so, do you have the part number handy?

Thanks

Hi,

I've got the "Mamba" hose on mine, there's an eBay link further up the thread. Strangely more expensive to buy it directly from Mamba own website than through eBay direct from them!

Just been trying to fit that mamba feed pipe today on my 1.6 D( mini) basically same as 1.6 hdi 110hp, and it's seems too long and incorrect length, also the angle on the top banjo fitting it's too closed...touching the actuator.
Sent message to mamba to.see what they will reply, but definitely is not right on the length(at least 15cm longer) and that angle at top banjo.

Actuator rod is on the front from memory (on the VNT turbo of the 110 hhp DV6 - can check in the light if day tomorrow) is your pipe as per my picture above? I.e. heading towards the engine (and cranking downwards towards turbo)

[Cretustf_21]

Good morning.
Yes it's at the front the actuator.
I will have a go again today to see if I will fit it.
But, all I can try it's to try after the fitting to bend opening the angle with pipe fitted on the turbo, bit I feel there will be a risc of cracking it by the round bit- exactly where it's welded the pipe.
Other options it's to weld the original pipewhere is the moving bits at each side, and in the corect position ( this options is a risk of the original insert to melt and dislocate moving to the turbo shaft)
Hmm I don't know what to do as I don't really want to fit a new original model turbo feed pipe.
If you got the mamba fitted, can you upload some pictures?

[Cretustf_21]

...also I don't like how short are the mamba banjo bolts are, so that's the other reason which make me think to weld the original pipe.

[Cretustf_21]

..now weld it the old one.
Just trying to convince myself it will be good to go, and no damage occurred to the turbo.

[MattBLancs]

Neatly welded, hope it does the trick. The cut open one seems to have an O-ring as sealing mechanism between rotating outer and pipe, not sure the rubber would enjoy the welding heat?

I'll try and get some pictures if still needed, but you were pointing the pipe forward, towards the front of the car (which I tried first) I found it fig if points from turbo's banjo bolt towards the engine

[Cretustf_21]

Good morning.
Yes , he done a good welding job, but somehow on the top banjo is a slight deviation and won't seat properly, probably he misaligned my marks, so not using it ,.... but it's a good try and guide to sort the risk of leaking forever.
The oring inside it's still in place , and didn't melt and come out.
So I.m back on the Mamba one, which I decide to fit that one now. What I've done, I did make a thick strongish rubber sleave around the top banjo bolts fixing pipe, fix it in a small vice, than 1 6mm bolt with nut(35mm long)and 2 washers blocked the hole where is going the banjo bolt nice and tight, that while is fixed properly on the vice I used a 7 mm long extension socket on the remaining end of the bolt and I pulled in the way to open the angle of that neck slowly and carefully not to bend or crack the weld....and it works, now I have 3mm gap between the pipe neck and turbo actuator.
Now about the length of the braided pipe seems to be right, ...see below the picture how is settled.

Suggestions accepted!
