Turbo gone again!!!

[Argos69]

I would definitely remove the filter from ANY 1.6 hdi that I owned .

Well if your turbo has failed due to oil starvation, there is debris in your oil, I would say this affects most of the 1.6 hdi,s on the road, especially with typical UK use, ie short journeys and lots of traffic.
Removal of this debris is just about impossible, the engine is polluting itself with rubbish via the dpf and particularly the Egr valve.
The problem can be solved by stripping the engine completely down and cleaning every part, to as new condition. This is never going to happen in most cases due to cost, or a new engine could be fitted.
My answer is to remove the filter, this is a low cost solution, that has worked for my customers allowing me to offer a guarantee with the turbos I fit.
If you do not remove the gauze in any way, and just fit a new turbo on one of these engines, I would say it is 90% likely that it will fail within 12 months.
The tiny particles of sludge, or whatever the contamination is appear to cause no major issue to the turbo, whilst no oil at all will certainly kill it.
My son runs a 206 GTI HDI, and it has done 20k of very hard use , with a remap up to around 140bhp, we removed the turbo about 2 months ago and sent it to midland turbo for testing, and they noted no deterioration at all, and it was fitted straight back on the car. This has been our test mule for many extreme ECU maps.

Hi & thanks for sharing your knowledge on this subject. This might be a really naive question, but is there any logic in thinking this mesh oil filter sounds like it should never have been fitted by PSA as it's such a gremlin, so should it be removed from even a healthy engine if the opportunity arises?

Sounds good to me! What's the best way to do that, replacement parts (modified) or mod the existing one? Is it straightforward-ish?
Thanks again

At the end of the day a turbo should at the very least last the life of the car looked after anyway. I might have a crack at removing the mesh filter at some point.
At least you can get to it with the turbo in situ.

There seems to be some debate as to whether the notorious mesh is at the top or the bottom of the turbo oil feed pipe. Does anyone know for sure?

Reason I ask, is that I looked at my turbo this morning and the oil feed pipe is really easy to get at, at the top, but it turns into a flexible stainless hose and then vanishes beneath the turbo..... :eek:

Looks like the bottom connector doesn't want to be seen, let alone found.

Any thoughts?

Recently I sold my Vectra C 2.2DTi, a rather solid engine but with a reputation to kill turbo's. Reason seems to be the same, sludge in oil feed tube to turbo, and loss of oil pressure. This engine also has an "aggressive" EGR, and despite loss of DPF, it has a cat. Many owners and mecanics has done some good job to try to find a permanent solution. In the Vectra it is not possible to block the EGR, there is too many sensors giving faults (one company in Norway says they should be able to remove the EGR function by reprogramming the ECU, but AFAIK no-one has done this yet). Removing cat is one option that helps prevent oilsludging, but not everyone is eager to do that.
There seems to be a clear connection by the way you drive, how long trips, amount of starts with cold engine... Classic for all engines, but modern engines seems to be more sensitive?
I bought my DTi when it was at 100.000KM in 5 years, and only 2 oilshifts, following the service interval at Opel. AFAIK most of this is in citytraffic, and with alot of short trips.
Just by looking with flexi-camera into valvecover, I could see quite some light-brown deposit. I clearly wanted to get rid of this, as easy and safe as possible. At first I replaced oil and filter 3 times within a few weeks, using cheapo oil (within spec of engine) and quality oil filters. This helped quite some, but still it was some sludge left.
Now I've used "Royal Purple" oil in all my motorcycles with success, for several years, I wanted to try this brand oil in the DTi. Fully synthetic 10W-40, and a new filter. My oil-supplyer advised med to check/replace the filter after a few weeks since this oil should loosen the sludge. And they where correct: A few weeks later I replaced the filter, and it was seriously in time! I have never seen a filter more filled-up with gunk! In later oil changes, filter was more "normal". Now, when I sold the Vectra, it was at 206.500KM, and the inside of valvecover was absolutely shiny.
I have also removed the turbo oil pipe recently, just to discover this is free of sludge, as it was not when I bought the car: It was pretty much blocked, used a good 20 minutes with kerosene and pressurised air to remove the gunk...
Point is, I'm not the only one to discover that frequent oil/filter change, and using a oil with good cleaning properties (I have used bobistheoilguy.com as a resource to find "my" oil), is essential for an engines "good life".
I have clocked my Vectra to be at least one second faster from 0-60Mph than factory says, when I bought it, it was at spec. A good bonus!

Now I have bought a brand new Berlingo, included "freedrive" service, I am seriously considering buying the RP-oil to the Berlingo too. I'll guess I can buy alot of oil for the cost of one turbo :whistle:

Hi guys i have read alot of write ups on this turbo problem and so i have a couple of questions myself,
1. Is removing the gauze the right thing to do people talk about it but noone seems to sure, any experts out there.
2. could i replace my oil feed pipe with a modified bigger one? would this have any side affects?
would be greatful if these could be answered with as much info as possible, thanks again guys. ( worried berlingo owner).

So, when we get our brand new Berlingo e-HDi next week, this filter inside the pipe is still there? So, it might be an idea to remove it ASAP?
