Hi All,
When I bought my 86 volvo 245 three months ago,The vlavo cover gasket leaking as below:





Other BBer told me that the flame trap might be blocked and cause the crankcase presure high and force the oil leaking.

About two months before, I clear the flame trap and changed the valve cover gasket. I keep one eye on it and there is no oil leak from the valve cover.



But, three weeks ago, when I change the trany's fluid,I noticed that there are serverl drop oil between the engine and the trany(see the location that two RED circle there).



Also, I know that the drain plug leak(might be the bad cop washer circled by black line).

And now the engine oil keep leaking from the two place.

Except the drain plug,Is it possiable that the rear crankshift seal is bad cause the engine oil leaking between the engine and trany?

If so, how hard to change the rear seal? How long,Special tools, other parts or work I can do during the process... etc.

I must make decison before the winter come in.

Thanks.
