I'm hoping someone out there has some insight on this issue. I've got a Volvo A25D that is filling the bellhousing with engine oil after a few hours of operation. Rear main seal and the seal between gear case and bellhousing have been replaced, but issue persists. Pulled the starter this morning and oil was running out. Went ahead and replaced the power take off lube/drain pump as well since it didn't seem to be pumping oil out of the the pto gear case that is bolted on the bottom of the bellhousing. Ran the truck awhile and checked engine oil, found it very low. Pulled starter and of course bell housing is full again. Its not making a whole lot of sense to me, hopefully somebody has a lot more Volvo experience than me
