Bad PCV / Oil Trap / Breather System On 2007 Volvo XC70
HTML-код
- Опубликовано: 17 янв 2025
- After experiencing a P0027 Breakdown (See Part 1: "P0027 Breakdown" replacing the Exhaust Cam Solenoid), I discovered oil blow-by / crud on the bottom of the oil pan during a routine oil change. With the car still not running, this is a perfect time to replace the entire Volvo P2 PCV / Oil Trap / Breather System.
We have owned the XC70 4-years with no documentation of any replacement to the PCV / Oil Trap / Breather System components. During the prior oil change, I tried the 'glove test' which was fine - but clearly something changed over those 3,800 miles resulting in an accumulation of nasty oil crud discharge from the oil trap box and oil dip stick tube lower port.
This is part 2 within a 3-part series with the XC70. Stay tuned for Part 3 COMING SOON as I attempt to put everything back together with all new OEM Volvo PCV / Oil Trap / Breather System components.

I have one already torn down, but I wasn't sure how to clean the return channel. Thank you!
Nice video
Thank you for the video and your want to create this content. I found it very helpful as I'm about to tackle the breather system in my S60R. It's a love and passion. But it's also fun to self diagnose. I'm looking forward to updating my breather system. Also thanks for bringing up the spacer for the throttle body.
I just did this PCV job. The coolant that flows through the metal pipe is hot to prevent the oil/water vapors from freezing if you live in freezing temps. That is why there is a PTC nipple that also heats up the vapors prior it going through the turbo. You can stick a long nylon straw cleaner up that metal pipe at both ends and if you do not see any oil residue then you do not need to change the pipe and just change the hard PCV nipple hose with a ID 4mm heater hose. You must use OET clamps where there is high pressure air flow so that would be from the 2 hoses attached to the oil trap box.
To get to the banjo bolt....next time, use a few extensions and go from the bottom of the vehicle... It's dirty but much easier to put on and take off.
On a side note. Finding cracked/worn seals is to be expected at high mileage. You can replace them as you go along since most will still operate. But unfortunately when you move a part with worn seals/rings, they will fall apart when removing. That's universal in all cars.
coolant drain plug doesn't come out, you just turn it 90 degs and then open the coolant pressure tank cap and it will drain quickly.
Injector O rings and pintle caps should be replaced, you already broke one so swap them all.
How did you get the left bolt on the PCV box? It’s blocked by that metal frame piece or something
I talk about it in the next reassembly video: removed bracket/wire from back of alternator and then access with an extension straight into bolt. :)

I didn't have this issue on the 2002 V70 2.4T, just on the 2007 XC70
@@jamiecars we ended up getting it thank you
How much that job could cost?
PCV Breather Kit parts sourced from IPD as OEM Volvo and added their phenolic throttle body spacer. Total parts & shipping $600 (USD).
I have a 2001 s40 1.9 turbo 4 cylinder. And I’m in the process of replacing the pvc valve system. And what I ordered is longer than the stock pvc valve line. Do you fix Volvos?
I'm not a mechanic - just working on our older cars. Go to IPD to see parts for your 1.9 engine - or FCP Euro. That's where I buy my Volvo parts.
Volvo 1.9T is a 4 cylinder block. Sounds like you received for a larger Volvi 5 cylinder block: 2.3T, 2.4T, or 2.5T - or even possibly one of the larger 6 cylinder blocks: 2.8 or 3.2...
Take the ipd TCV off the other car before it fails. Stay OEM, it’s not an upgradable part and the ipd unit is known to fail.
Interesting. The V70 2.4T lacked it's prior power so I installed a turbo boost gauge and confirmed it was barely hitting 6psi and any subsequent pull would only reach 4-5psi. I was told this was a sign of a failing OEM TCM. I installed the IPD TCM 2+ years ago and it consistently and repeatedly hits 8-10psi - every pull. Power is much improved since installing the IPD TCM.
What symptoms should I be looking for if the 2+yr old IPD TCM starts to fail?
This video's XC70 still has OEM TCM and hasn't experienced any of the power loss like the V70 2.4T.
@@jamiecarsit’s a simple solenoid that’s controlled by the ecm, the OEM unit can fail over time but it was probably the lines had a vacuum leak. The ecm will limit boost if it can’t reliably control the psi. Inside the ipd unit is plastic and it cracks after enough heat cycles. Most R tuners won’t even touch a car with one.
