Oil separator diaphragm ahs gone on my ST.

Parts on back order at Ford probably due to high number of diaphragm failures. Could be weeks.

You can only buy full separator unit from Ford. Does any one know if the diaphragm itself can be bought on its own from Volvo perhaps and if so is it easy to change.

Mates car was in the garage yesterday for this unit to be replaced! And i had never heard of the problem before

Chris and Dawn

Neither had i. Cars only done 30k aswell

Very common problem.

2nd generation T5 Volvo uses the same item.

If left for too long, it will cause engine breathing issues.

If you want to confirm that it is the diaphragm @ fault in the oil fiilte housing/separator, while the engine is running and the whistling is present, remove the dipstick and the noise should go almost instantly.

Chris and Dawn

Yes it's deffo gone cars been into Fords today. It does as you say above.

Do volvo sell this diaphragm separatley??

iansoutham

No, it is the whole assembly. Ring your local Volvo dealer and ask if they have any in stock. Explain it is a 2nd Generation T5 engine and they will know exactly what you mean.

Mate of mines had this fail on numerous occasions, fortunately all covered by the warranty.

I'm not 100% sure but there might now be an uprated one.

Anyway if your having trouble getting one from Ford, you might want to try Profile Automotive (Wolf/Code Red)

Cheers for that.

I believe they now do an uprated one and have got it on back order.
Just want the car useable until it arrives.

I think I'm having the same problem here... Interestingly mine happened straight after my 37.5k service on my ST3. I'm convinced Ford did this.

It's been back into Ford several times and they can't work out what or where the noise is (muppets) and have finally said you'll have to live with it and see if it gets worse!!! Could be the turbo they said, costing Ł2k. Jeez.

What a joke....

Anyway, I searched on-line and saw this post and I'm convinced this is what I've got, cold start, whistling noise raising with revs. Mine's bluefin'd and it makes the noise around 2000rpm.

Gonna do the test with the dipstick and then get straight onto Ford and get it in.

I hope Ford do this FOC as they have clearly damaged the unit.

rich_peel

Ok, so my ST3 has been into Ford now. They have confirmed it is the oil separator diaphragm that has gone.

I have been given a quote for the full unit of approx Ł220 + labour of 2.5 hrs

Can I get the part cheaper from somewhere else?

Please help?

I think this has just gone on my mates ST, has anyone had the work carried out and how much was it to get done and where's best to buy part from

turbo_3dr_tommy

has anyone tried to do this at home ? and do you need anything else while you do this

Its not a difficult job, you need to remove the airbox assembley to get to it which is a pain. sometimes the breather hose from the assembly to the block can be damaged which mine was and needed to be replaced as well.

Have a look on FSTOC , im sure theres a 'how to' guide on there.

anyone got an pics of what has broken?

there's a little box at the back of the sump as well which is what i thought it was but now you are saying it's behind the inlet manifold?

stishy

i had the exact problem, had to buy full unit from ford

turbo_3dr_tommy

how much was that mate ?

turbo_3dr_tommy

you have to be a paid member to view that section mate can anyone copy and paste onto here ?

Its under the airbox at the front left of the engine. The oil filters are paper elements like in the VAG diesels. You can see it under the front left of the inlet manifold. The breather pipe is the one that goes under the spark plug cover at the front.

I had a loud howling coming from the engine and high oil preasure.. So I change the oil diaphram and the oil preasure is a bit better not as high.. BUT when I re attach the breather pipe to the crank case it makes a noise again not as loud but still there... Doing my Nut In.. Does anyone know W. T. F. Is going on.. Could the Crank be blocked???
Also lost power and Sod all boost just a whisper.. Keep looking at my slege hammer losing the plottt Now...
