Oil Problem any ideas, please?

Another cheap fix is the "rubber gasket" under the oil filler cap. It costs a few euros for it.

To check for clogged PCV: remove oil dipstick, start engine, then check for pressure coming out of dipstick tube and possibly a small amount of smoke.

All Volvos with the PCV oil trap will clogg! It seems to happen around 70-100K miles. It requires a replacement kit (new plastic oil trap box, with various hoses and connectors, and an intake manifold gasket.) Average mechanical skills, persistance, patience, tools (but nothing special), and some good prep from resources on line. There are good resources on line by a few people who have prepared excellent directions and pictures.

When I changed mine, I marked off the whole day. It's advertised as a job that can be done in 4-5 hours (most likely only if you have done it before.) I took my sweet time with slow methodical and detailed approach to accomplish the job. I took some breaks at planned intervals to control my frustrations and to help maintain a positive attitude and perspective. There are alot of things to disconnect to gain access, and of course, it's critical to put it all back together again--correctly, the first time. I always keep a log with numbered operations. It makes me slow down and can be quite helpful in a multi-step operation--especially when you reassemble. For resources, I could not find anything in the manuals that I had available. However, the online resources by fellow D-I-Y's and also from some helpful techs was invaluable.

In the end, I know it was done throroughly because I had the most vested interest in it. It takes time and patience with alot of care as no matter how careful you are, you will drop parts in the engine compartment. If I can do it, anyone with average skills and no-fear can also!

I just replaced my PCV system for the first time in my cars history at nearly 140,000 miles, and it was not even clogged much at all. I turned it into a 2 day job. Day 1 was taking it apart and replacing the parts, Day 2 was putting it back together slowly and carefully so I would be confident that the car would fire up on the first try.

Turns out that it pays to be patient, car started up with no major issues on the first go.
