Hello Don:

Other than the Volvo kit you recommend in 700/900 FAQ "Crankcase Ventilation: A Treatise", what can one use for PCV hoses on a 1986 760 Turbo? I already have a new breather box and new three way nipple connecting upper hose coming from air intake, lower hose going to brether box, and small vacuum hose to intake manifold. I asked for that kit from a source for Volvo parts and the guy on the phone told me he didn't know what I was talking about. I also looked locally for generic PCV hoses from Western Auto and Pep Boys to cut to size, but found none. Thank you for your help. Best regards.

Rafael --

First, if you substitute hoses, be SURE to use a hose compatible with oil. Heater hose, for example, is rubber and is NOT compatible with petroleum products. Genuine rubber will swell, soften, and fall apart.

But I'm confused -- from your description, it sounds like you've replaced all the key components.

Final, you should be able to get the "kit" from a dealer. Just because someone told he didn't know what you were talking about does not mean it does not exist. It simply means he doesn't know about it.

Thank you for your prompt reply. Following instructions in 700/900 FAQ, I tried to change PCV components. Sure enough, they were desperately needed. The nipple was completely plugged up and hoses were not better. Engine seals front and back and distributor seal had to be replaced. I got the breather box from Swedish Engieering but they could not supply the kit. I got the nipple too. I was aware heater hoses would not do, but could find no hoses. I cleaned hoses on the car as best I could with carburetor cleaner. Still, they soil things helped by dissolving effects of Mobil 1. Vacuum is good now. I would like to change those hoses to keep things as clean as possible and seals in place for as long as I can. If you know the P/N for the kit, please let me know it. Lacking that, what kind of hose can I use. How about 5/8 inch hydraulic hose? Thank you for all your helpful posts at Brickboard and any information you can give me now. Best regards.

Last time I went to dealer parts counter for service stuff, I got new trap, new rubber(?) cup, new three-way plastic piece, and then I saw that they wanted about $12 for the small hose. The other items are shaped and designed for our bricks, that small hose is 12 cents a foot at AutoZone or whoever, and replacement labor is nil. The price was around $16 all together. I bought about 4 feet of the small hose.

There really is not a kit, they just feed out the parts as needed. Not all are needed every time (you can bet they sell'em anyway). Can you go in person to a Volvo parts counter? I find that a visit on Saturday is best as the techs aren't popping in an out and there are other DIY-er's there, too.

Good Luck,

Bob
