[Engine] 1.6 HDi Turbo Oil Feed Filter - Keep or Remove?
#1
I took the turbo oil feed pipe off of my car today to check the gauze filter. It's completely clear of muck and I've given it a soak in some petrol to be sure. I'm wondering if I should take the filter out before I put things back together?

Thanks

If it's 'completely clear', why mess with it? It's obviously been performing well for ages.

Keep the filter in case a big lump of crud comes down the line ....

At the end of the day it's a matter of opinion id definitely get rid, (Have done several no comebacks) rather take the chance on a bit of crud getting through then oil starvation.

Yeah, that's where my head is too. Can't say I've read anywhere that taking the filter out causes problems.

Seems that Citroen also recommend removing the small strainer from the feed pipe, see attached. In the same section of DocBackup for the M59 1.6HDi there's also an item about replacing the standard strainer with a larger one on a different bolt (p/n 0376-56 or -60?), it seems either remove or replace are both valid options.

I dont think this is a Citroen bulletin but a turbo company as Citroen modified the turbo filter and made it bigger the replacement part can be bought.

It's from taken from the PSA DocBackup service manual, which I think is also called ServiceBox when combined with the Sedre wiring diagrams. It's not the latest version as they are now only available online via subscription but there are earlier versions available with a little searching and a fair bit of faff to install.
You are right about the replacement part, it's the part number I listed in my post. For completeness, I've added the upgrade section from the same manual.
There is a French turbo company (maybe others too) that's used the French 110HP version of the document and put their logo on the bottom, in fact that's what lead me to look on the English version of DocBackup.

Do we know what years they started using this new bolt from ?

I get rid of them.

If it's there and a lump of muck gets pushed through the oil filter bypass or an accumulation of fine stuff gets pushed through, then it'll block the gauze which will starve the turbo of oil - net result = new turbo cartridge needed.

If it's not there and a lump of muck gets pushed through the oil filter bypass, or an accumulation of fine stuff gets though then it'll get pushed up to the turbo bearing and starve it of oil - net result = new turbo cartridge needed.

To be honest I don't think it really does anything having it there, if muck gets through to that point it'll kill the turbo bearing either way. Providing you do regular oil changes and use decent oil filters dirt shouldn't get through to there anyway.
