could be the possible cause or causes of this
Any help in this mtter would be excellent

Sounds like a plugged "flame trap" (underneath the intake manifold) and it
caused a leaking seal...

A very common problem - the flame trap is plugged, causing crankcase
pressure to build up. An incredible amount of oil can be forced out in a
very short time; our '85 Volvo expelled about 3 quarts before I could get
off the freeway!

Check out http://www.volvoadventures.com/howtodoflametrap.html for details.
Don't let this go on very long as seals can be pushed out. Most of them can
be pushed back in without great disassembly, but better to avoid it.

Another posibility is the front oil seal. If the oil is dripping down onto
the water pump, it is a good indication that this seal needs replacing.
There is another at the rear, which is often replaced when changing the
clutch as a matter of course.

For info - the crank case pressure build up problem is, as previously
mentioned a common problem. On the later models and in particular B200
engines, advice from The Volvo Owners Club (UK) is to simply throw the flame
trap part away as Volvo decided that they were of little or no use. Also by
doing this, you allow the engine to breathe easier thus reducing the
tendency for it suffering from pressure build up.

So you pull the housing out, remove the trap from inside it and refit the
empty housing? Given that the flame trap is a restrictor to limit the
volume of crankcase vapour going into the intake manifold, does this
change the way the engine runs at all?

It isn't meant to restrict gas volume, but to arrest any flames from
a backfire. No effect on how the engine runs - you just want to hope it
doesn't backfire and send a flame through that hose...

The advice to chuck the trap came from The Volvo Owners Club who advised
that Volvo themselves stated that the trap could be chucked! Can't think of
any one better to believe.

Has anyone heard out their any knowledge of having removed the trap?
