Checking PCV

[norcalmendo]

How do I go about checking the PCV system on a 07 XC70? How hard is it to replace?

There's plenty of good info on how to check the PCV on this site, i suggest using the search functions. With respect to degree of difficulty, i reckon it's a doable thing for anyone with moderate wrenching skills but most important is a willingness to prepare sufficiently beforehand.

Thanks. I did the glove test and there is suction. Hopefully its fine for now. Car has 102000 miles on it.

Now repeat the test with somebody revving engine above 2500 RPMs.
