I want to validate the correct placement of these hoses.

Looking at this picture, I'm refering to Hose #6 and hose #8 and their placement on #1.

They fit on either nipple. I've seen pictures and it is never clear which hose goes on which nipple. Several pictures contradict each other showing the hose on either nipple and therefore I'm clueless.

If you have a S60 2.5T please take a look at your car and see these hoses throught the gaps in your intake manifold and they me if hose number 8 is on the nipple closer to your throttle or closer to the engine block.

 

the photo you posted is correct

 

For future reference.

The picture is wrong for a 2005 S60 2.5t.
Hose #8 goes on the nipple closer to the engine block.

 

well on my car parked in my driveway the hose #8 is on the forward/left nipple and the hose #6 goes on the rear/right nipple.

 

Thanks for taking the time to validate.

 

lol sorry we could not give you a consistent answer.
but basically if you look into your oil trap through both openings on the top one goes straight towards the bottom where as the other one does a bit of an "S" bend, the hose labeled 8 goes in the opening straight to the bottom of the trap the other one #6 goes in the "S" bend looking this

perhaps you can find a cross section of the trap online to better understand what I'm trying to describe lol.

 

it is really easy to remember this. top hose hugs block, always, and PTC hose wraps around the engine.

 

Confusing answer

 

The hose that goes to the top of the engine is always the hose connection on the box closest to the engine. The other hose connection is for the hose that goes elsewhere. That is how it is. Get them mixed up and you will have positive pressure problem that could cause blown seal or worse.

 

I'm not sure if your answer is correct. But it looks like the advice from others that the 2005 model changed.
But to discuss the positive pressure: Oil cap off and car running, you would have suction?

 

you are talking to someone who has done a few hundred of these things.

they did switch in the 2004+ years, side to side, not front to back. they made the change because of an intake manifold change and had to hove a hose location so that they would use the same upper hose as they always had. Still that port was closest to the block.

the pressures here are <5 PSI. you need to have a special gauge set-up to read. And yes 5 PSI is enough to blow a seal. Actual pressure may be much higher, but it is bleed off because of the volume. When a piston comes back down, it moves the same amount of as and close to the same compression as it would on the topside of the piston in the combustion chamber. If your crankcase vent system is clogged seals litterly blow.

purpose of the Volvo Vent system is to create a NEGATIVE pressure in the crankcase to get the vapors to actually sucked out by the intake vacuum.

 

lwith the engine running at idle there is normally supposed to be -0.2 Kpa of pressure, 0 means partial clog and anything "+" means (normally) that there is a clog in your banjo bolt between the intake and flame trap. and at any kind of speed it should never go above 0 Kpa.
from what I understand between 04 and 05 there have been no changes to the pcv system, and no if you cross the hoses you will not get positive pressure you will suck up oil into you intake manifold and burn excess oil.

Lifesgoodhere is correct here in saying that the top hose (in the photo labeled 6) always goes closest to the engine block.

 

Guys, I'm getting conflicting information from various forums. This is the reason that I asked for someone to look at their setup on their own car.
I respect everyones opinion but I'm confused!
Can someone with a 2005 or later year post a picture of their car to clear this up?

Thanks.

 

according to VADIS for a 2005 S60 2.5T the photo is still correct here is the screen shot.



if you want to be even more specific send me your vin number and i can look up your car.

 

I think thats the same picture I posted to start this thread. But keep in mind that there was a change in the engine during 2005 which requires me to order a large elbow hose.

 

remember the "general" position of the hoses have not changed since 1999! not front to back positions anyway.

this pic is from eEuroparts for the 2005 s60

 

and if your STILL not convinced this is a cross section of an oil trap, they are all set up the same way with a divider so you don't suck oil into your intake from your valve cover. take yours out and look in it with a flashlight. and next time you work on your car take some photos, its always saved me tons of time!

 

That's not my flame box. It seems that mine is about a third larger.

 

if it's not what is pictured then it's not an oil trap for a 2005 Volvo S60 2.5T or any S60. it could be some sort of aftermarket knock off. if it is an actual Volvo oil trap however it absolutely IS hooked up as previously stated. if it's working the way it is then forget it and assume your correct, if its hooked up and not working then change the hose orientation. and if it STILL is not working bring it to a Volvo dealer and open your wallet. good luck to you whichever way you go, honestly. it would be really nice if you don't have to take your intake manifold off twice, think of how easy this repair would be if that darned box was moved to the right. lol but Volvo cant make things too easy for us can they?

 

I guess thats why we drive Volvos. We love a challenge. Lol
