oil leaking out oil filler 240DL

[Zoraster]

I have a 1988 240DL volvo.

Suddenly I am having a problem with oil leaking out the oil
filler opening. I bought a new cap thniking it was an old gasket problem.

it is still leaking.

So I guess there must be a value of some sort that is plugged and causing
pressure in the crackcase.

Anyone have an idea and have seen this problem before?

TIA

My guess is that either the flame trap is plugged, increasing crank case
pressure, or that some of the oil passages are plugged. The former is
easy (if a bit grubby) to fix, the latter could require significant
disassembly.

While specific to the 740/940 series, there is info for the 240 as
well.
