[Engine] 1.6HDi Turbo Oil Feed Pipe - Flexible Banjos!
#1
When I took off the turbo oil feed pipe earlier in the week, I found that the banjo joint at the turbo end of the pipe was able to move by twisting & sliding on the pipe. As it's 10 years old, I thought the joint must be faulty so I bought another pipe which arrived today.
Looking at the new pipe, the banjo joints at both ends are flexible, I can turn the banjos on the pipe & I think they will probably move along the pipe to some extent too.
I thought that maybe I'd bought a duff pipe, but it seems usual according to this video from Ajusa which by chance is also the brand I bought.

As far as I can remember it is normal for banjo to move when it is not bolted up.
There are two different types of pipes on the 1.6 HDI the 110 is slightly thicker and uses different banjo bolts compared to the 75 and 90 engines.

Thinking about it some more, I suppose that there has to be some flexibility to allow for manufacturing tolerances on the pipe, turbo & engine. Making solid joints would put stress on the joints straight away if all the parts did not line up perfectly.
From what I've seen & read elsewhere about these joints failing over time plus the amount of faff to get the pipe off it may be good idea to replace the pipe if in any doubt. The turbo end must get quite hot so maybe the seals go brittle. I put a large screwdriver between the banjo & the turbo to get the bolt undone without twisting the pipe, that was after the joint twisted and made a cracking noise.

A quick update, I found the attached on DocBackup, clearly the joints are meant to be flexible & are a bit fragile by the looks of things. There's also a note about the strainer so will attach again to the other thread I created on the strainer subject.
