at my volvo 240 there is sometimes little oil-drip at the bellhousing/engine
brace (just a little bit: 1 drop in three days). Where is this coming from ?
the rear cranshaft oil seal? Gearbox?

( I thought the sympton for a leaking rear cranshaft oil seal, was oil on
the outside of the oil-pan. In fact the outside of the oil pan is always
wihtout any trace of oil. ?

Check the valve cover, sometimes it trickles all the way down. Rear main
seal can also do this, sometimes the oil pan gasket, but usually the latter
will get oil on the pan.

Thank you for your answer.
There is no trace of oil from the valve cover . So I understand it is
"sweeting" from the rear seal. I found out that the flametrap was also
clogged. I ´ve cleaned it yet. Is it possible that the dripping/sweeting
now stops? Or do have to renew the rear seal anyway? (the seals were
already changed bij the former owner; 10.000 km ago)

thanks in advance Tintti

Wait a bit and see. Clogged flame trap can definitely make seals leak. It
can blow them out too, but usually when that happens the leak is very bad.

Thanks!
The oil dripping has stopped (I drove 500km´s after my last message. But is
it possible that there is still al lot of in the bellhousing ? (I mean is
there a gasket between the bellhousing and the engine)

No, anything in there will drip out.
