PCV vent hose broken

[firstv70volvo]

Been trying to remove the lower part of the hose at the box : my hands are a bloody mess and I just cant seem to find a way to remove this damn clamp , the face where I should pry is facing the exact opposite of me.

Any tips on how to remove it or is there a safe way to destroy it without breaking the box itself ?

Have you tried removing the two 10mm bolts holding the box to the side of the engine and moving it out some for more room? When I did mine I used a small flat head screwdriver to pry the clamps apart.

I ended up managing to cut the clamp with some pliers who were too short for the job , had not much leverage I hurt my hand so many times on the starter and on the manifold haha. Those clamps are pretty solid I can tell you. Took me way more time than expected , gonna fit the new hose tomorrow it should be a breeze compared to this.

@first70volvo
Are you talking about the box close to the timing belt ?

It really pays to remove parts to get good access to things. On the P2, we get fantastic sight lines and high fuel economy due to the engineering of the engine in an incredibly compact package, but going to work on things means disassembly.

there are tricks sometimes, but on a job that should last 100k miles, taking the time to do it right is a good path.

I fought the PCV banjo for about 60 minutes on one bolt and will never do that again. Removing the alternator in 15 minutes makes that job a 30 second job.

I agree that I probably could have made my life much easier by removing some parts that were in the way. I guess this kind of wiseness comes with experience. Im not much of a mechanic but I want to learn ,a bit scared to remove the parts I should sometimes.

Also since I just wanted to change the hose before I send my car to my mechanic I just wanted to make a quick job and not dismantle everything. Not going "quick" so far haha

I replaced that hose on our 2.5t without removing the manifold. As I recall I DID remove the throttle body so that I could attack the connection at the breather box from the side.

By the time that PCV hose is broken, the Throttle Body needs to be removed for cleaning (I wrote a Throttle Body DIY in XC90 forum).

The take away here is short cuts don't always work. Taking out the intake is not that bad a job with a swivel 10mm socket. It also allows the PCV system to be fully inspected and TB cleaned.

There are many write ups and videos on the process it makes sense to just go for it. I suppose if one is experienced with the car and the process a short cut would be warranted.

Thanks for all the advice guys

I know the hose being broken is very likely a symptom of likely bigger problems.

Im new to mechanic stuff so I see this as a warmup for bigger jobs. It went alright in the end the hose is changed and I did it myself.

One thing not mentioned on this thread is that the griminess of your oily mess indicates the return oil flow path to the oil pan (from the breather box) might be clogged.

I'm gearing up to do my PCV system (bought the parts) on my 2007. My glove test doesn't blow up (BAD) but it doesn't suck in either. The glove just sits there.

I was wondering is long strong pipe cleaners (think chemical lab supply shops) would be enough to run through the passageway.

I was thinking to drain the oil and run said pipe cleaners with liberal amounts of solvent (denatured alcohol) in and out like a madman.

Big and long zip ties are good for the passage
