I just put a new pcv system and I was hooking all the new hoses up and the hose that hooks to the air intake on the right side of the turbo is covered in oil is that from the pcv vavle not working and how do you tell that it does not work. I also need a good place to buy intercoolers hoses any ideas who has the best price Thanks jared

 

I assume you changed all of the PCV system. There really is no PCV Valve per se.

For the other hoses you can look at OEM, Samco, or Stylin Motors. The Samco and Stylin products are silicone.

i changed the whole system what and how does the work do you think that was the cause of all my oil on my tubes

 

Unsure how the Volvo works but atleast previously in my Rx-8 the pcv would recirculate any fumes be it gas or oil back into the Throttle body. Could be over the years that the oil fumes slowly clocked up some of your tubes. Unsure if any Volvo owners have installed Catch Cans but that is what most of us 8 owners did. Its amazing at what a see through one collects and your able to see.

 

Yes. Some people do install catch cans. If you had oil on your PTC system than it was probably a fairly clogged PCV system that had backed oil all the way up to there. There could be another reason why that would be caked in oil so don't take my word for it.

 

what else could it be

 

I don't know, but if you changed you whole PCV system and all new hoses and cleaned your PTC, then everything should be fine. If you run it for a while and your finding that there's still oil building up back there, then I would look further into it. But chances are it was just your clogged PCV.

 

If you are talking about the oil on the outside of the PTC, that seems to just happen with age. It is more oily dirt then anything else, at least on my car.

 

what is a ptc sorry dont know im going to try to clean off the old oil mess and see what happens down the road thanks guys for your help

 

The PTC system is the spot that the vacuum line connects too on the cold side of the air intake after the box and right before the turbo.

 

so before i did this pcv change i would start my car and it would rev high about 2000 rpms then settle down and also replaced all my vacum hoses or at least most of them is starts allot better does not rev very high any more. Do you guys think that it is a vacum leak thanks Jared

 

Does it idle normal, and drive normal and everything?

I don't even know how many different versions of PCV kits were available. This one could be answered most accurately by FCP Groton.
