Default PCV and charge pipe question

Hello everyone
i just did the glove test on my car (V70 T5 AUTO)and i did not get any vacuum
When I removed the dipstick I saw some light smoke coming out at higher revs, so i guess i need a new PCV

i contacted my local dealer, they wanted £200 pounds for a volvo kit however i see on partsforvolvosonline and ebay they sell the kit for £40 is there a major quality difference that justifies the price?

2nd
I was looking around under the bonnet and realised that the charge pipe was leaning on the intake manifold and it looks like it melted a little, is this ok?

as you can see on the second picture the support for the pipe on top of the manifold is missing

I thank you all in advance,

When I did my PCV, I only needed to change a couple of hoses, most of the old parts were absolutely fine. However, be warned that Volvo's obscene parts pricing policy went into overdrive at this point and just this one hose from a main dealer cost me £56 !!!

Hi.
Take a look at Parts-Monster on e-bay.
They have individual parts or kit of parts depending on your requirements.
I bought a basic kit for about £43 and then added extra parts as I needed them.
The important thing is to replace the trap canister and then to make sure all the oil-ways are clear , especially the return port in the block. This can seem to be clear but actually gets blocked down in the sump pan. The trick is to put a length of hose down the port and to blow down the hose . You should hear the oil in the pan bubbling when the way is clear.
There is a small hose that runs off the inlet manifold from a banjo fitting. this also has a habit of being blocked or the hose degrades and breaks. Be prepared to clean / replace this.
If you look at you-tube there are very good how- to s for S60 / V70s. I would suggest removing the electric fan as well because it makes getting to the throttle module and inlet manifold bolts a lot easier.

Well, a lot of people just say change everything, but personally I'd leave genuine parts in place if they are still fine rather than replacing them with aftermarket ones.

The parts we are talking about here are basically just hoses, a plastic box and one non-return valve. Hoses need changing if they have split or gone hard, the plastic box (oil separator) needs changing if it is blocked or cracked and the non-return valve needs to be changed if it is not working freely.

This is the best information I found about how the PCV system works on a turbo engine (which is different to non-turbo)

I fitted the kit from Parts for Volvos last weekend. Very happy with the quality and what's included. Bear in mind the original pipe clamps are all crimp type, so these need replacing. Screw types are included in the kit along with the manifold gasket you'll need.

The only other thing I needed was the gasket for the thermostat housing, as I just couldn't get to the end bolt on the manifold with it in place.

It might be you can, if you have small hands, but in the end I decided it was easiest just to drop the power steering pump and get on to it square.

The hose in my photo? The rubber had gone hard from the heat of the engine and I was worried that it would start to crack in the future if I put it back on again.

it may be a lot more fiddly but I would advise to do ALL the parts.

The long aluminium pipe that comes of the lower left hand side of the intake manifold has a very very tiny plastic tube that will be clogged with carbon / is easy to break - so its easier to have the part to hand than to find you need it with the car in bits and the wife going nuts
