Breather box replacement advice/instructions needed

: The breather box hose which is leaking oil

Hi my 2005 volvo s60 2.5T has got an oil leak on the air intake (aka breather box?) hose which is supposedly not covered by the warranty as it doesn't cover replacement of the rubber parts in the car. I was quoted $589 at the dealership (which includes 4 hrs labor) and $450 at swedish auto repair shop to fix the problem. Does anyone know what parts have to be replaced and maybe give me some instructions on how to replace them? It seems odd to me that a 6 year old car would get a problem like that and I couldn't find any other forum threads on the similar (relatively new) S60 problems (nor any S60 at all). But it's nevertheless happening to my car. At the dealership I was told it's a common thing to go on the car.

The system doesn't look too complicated from what I can see, just the of hoses and some clamps. I am not sure what is the source of the leak though, but from my conventional understanding something is clogged up and when the turbocharger kicks in a little bit of oil goes through the hose. The leak started recently and it doesn't seem that bad but I would like to keep my car in reasonably 'immaculate' condition, and I rely on it for roughly 2.5k miles primarily commute highway driving per month at the time. I would really appreciate detailed instructions (preferably with all part numbers to be replaced, the tools I would need and the stuff to watch out for when doing the repair) and some insight on how often does this problem normally happen and when to expect it happen again. Thank you!

The PTC valve by the turbo intake itself is probably clogged up. That provides most of the venting for the oil vapors from the system; so instead they are just being pushed through the turbo itself and leaking out your intercooler/hose connections.

Here's how to do it on an older 5-cylinder; yours is of course slightly different as some of the things have been changed or moved around between 1998 and 2005, but this should get you on your way.

Wow, if that's what it needs there is no way I will be brave enough to screw with the fuel lines and everything. I am comfortable enough with the tasks at the level of replacing a bumper or changing sparkplugs. And your hose system looks so different from S60. I also don't have a ramp or jacks, so if it's not something that can be done through the hood only, I wouldn't mess with it.

Btw,I graduated from VT (phd in CSES), so Blacksburg is my second home!

Maybe someone with S60 expertise can have their word before I go and pay all that money to the repair shop/dealer?

All from the top but a lot of work.
Do what was said first

A volvo mechanic told me that if you complain a lot, the dealer may do it under warranty.

i am 'friends' with the local volvo dealership, and they would know better to tell me if they could do the repairs on the warranty. Unfortunately this time i am likely screwed

In response to the above conversation: I'm checking on my breather box at the moment, on a 99 S80, because the Crank and Cam seals seem to be leaking.
Its not that hard to get to all this. And if you can change your spark plugs than you can do this, it just takes a bit more time to dig through the layers.

I have a question though, if the author is still around, and responding to this thread:
How can I test my breather box to know if its functioning properly without the gauge tool?
Is there a way to tell? Because without a new part in front of me to compare my old one to, I wouldn't know what to look for.
Any further info on checking through this system thoroughly would be a great help!

Hey, I ended up redoing my PCV system in the fall 2015, after my car had thrown a check engine light code for 1001 or something in 1000 range. This is supposedly a formal code for clogged up PCV. I also had two instances of rough idle with shaking in the engine on the start, which persuaded me that I need to fix everything within the next 300 miles. I replaced everything http://www.ipdusa.com/uploads/images_pr ... _17037.jpg
and it took me about two days to complete. It was nice that I was able to have my car parked in a garage for two days. I also replaced a radiator (for an aftermarket one, just $150 for part), as it was leaking. Let me know if you need specific instructions, I have a link to a really good writeup which I used, it's just on the other computer.
