As stated above I am working on a 1998 Volvo S70 T5 PCV breather system.
I am hoping MIJ can help me out with this, seeing how he just recently went through cleaning and replacing hoses on his PCV system.
I want to hopefully just clean out the PCV system, because I do not think it is to the point where it needs replacement. Some of the hoses and fittings look to be shot, so I am sure there will need to be hose replacements. I just bought silicon hose to replace all the vacuum lines and I would like to know which hoses on the PCV diagram can be replaced with either 3.5, 4, 6, or 10mm silicon hoses.
Referring to the diagram: I am keeping Part 1 (Cleaning it) I am keeping Part 17 (No need to replace) Which of the remaining hoses do I need to buy a replacement for and which can i substitute with silicon?
Zach, I did a non-turbo pcv system which is much simpler- I would actually recommend you get the entire long piece with the two hoses inside of it (#7?)... problem is the nipple on the oil trap and the other end (PTC nipple/valve) are very large- much larger than the 10mm hose opening. Actually on mine, I used a 10 mm hose and fit it "inside" of the opening on the oil trap and cinched down a zip tie over all of that...it's a tight fit inside of the opening so I'm hoping it will stay and not be pushed out with any pressure- since yours is a turbo, there will be even more pressure from time to time- stay with the OEM large section (#7)....I know this is the main one- Oh, and also the snorkel piece to the top would be very hard to get silicone to work for- the rest, you could use silicone hose- different sizes- just get them all out and see what fits as you do the job.

Sounds good, thanks MIJ I will order the part number 7. Gotta get the car up and running for a cross country trip, unfortunately I'm buying all the parts blind because my car is at my ma's house, but I need to order all the parts so they are there when I get there because I only have 3 days to fix everything up .
