2001 Volvo V70 XC Q&A
2001 Volvo V70 XC Question: Breather Box?
I had a dealer tell me that my XC70 with 129K miles has "positive crankcase pressure" and probably has a clogged breather box. The car runs fine, there are no codes being activated and no dash warnings. The car does not leak oil. I have read posts on other sites where people had this service done and had additional problems. I put a surgical glove on the oil opening and dip stick opening and I can't discern any positive pressure. should I let the dealer do this repair for an estimate of $700? Anybody? - Visitor

Problem with the breather system is a common thing on these cars over 100K miles. I'd get a second opinion from a Volvo specialty shop- just like Patrick suggested. The best tool to check the crankcase pressure is a Manometer, not a surgical gloves. There is also a banjo bolt type of breather connection under the intake manifold, which tends to clog. Actually we never replace only the breather box on these, we do replace the breather hoses too. Cleaning the ports on the engine block is a very important thing to do. Zee - ZeeTech
