PCV system cleaning
Hi, my s80 is blowing a little blue smoke at idle when warmed up and from research on this forum, I believe I need to clean the PCV system.
On Vadis, it says to remove the intake manifold to clean. Is that necessary? I believe I saw a thread where tech chimed in and said you could get to it without removing it.
Let me know and thanks in advance.

When cleaning the S80 PCV system, I read that there are o-rings that seal the filter, or whatever it's called :-), where it goes into the block. Are the o-rings proprietary Volvo or will a regular parts store have some that will work? I have 170K on my 2000 and this is the only oil leak I have. Will it cure it?

Man what a pain in the unowhat it is to get the oil trap off! That darn bolt on the left side of the trap is behind a bunch of stuff. Have to remove the alternator, A/C compressor, then the frame that holds them to the block. Glad I did though....it was all gunked up. It's surprising because I've had the car since 60K miles (now 172K) and have ran nothing but synthetic. And the smaller o ring was faulty which was causing my only oil leak on the car. I'm using carb cleaner to flush out as much as I can from the oil trap and hoses. Any other suggestions?

in process of removing intake
Ok, so I am in the process of removing the intake manifold. A couple questions for tech et al.
1. There is line that feeds into the fuel rail that I cannot get off. I believe Vadis says I need a proprietary tool. (fuel line quick connect) Where do I get one of these?
2. While taking out the fuel rail, I noticed that the injectors are dirty. What is the best way to clean these? Or is it better to replace them that is if it is cost effective. Let me know, thanks in advance.

Tech, thanks for your help btw.
I have taken off the fuel rail cover, and pulled the injectors out of the holes so all I have left is the rail with the injectors and the fuel line that runs underneath the manifold. I can only lift the fuel rail a couple inches as thats all the slack I have.
There are small hex bolts on the other side of the fuel rail where the injectors go in are those the t-25 bolts you are speaking of?

Progress....
Ok, got the fuel line disconnected after you wonderful tip about removing back cover of fuel rail (it just popped off, I was looking for the easy button!)
Now, I have to get the bolts out of the manifold. The top ones wear obviously easy but the ones on the far left and right are hard. Do I have to remove the alternator on the left to get it out? And on the right, there are some tubes that are obstructing the other one.
Any tips to get these out then I am home free to clean and service the PCV.
Thanks in advance, you have been a big help.
