Oil leak, between flywheel housing and block

[JMBT]

Hello all. I have a Volvo with a CM2250, 789K, and have recently noticed oil leaking on the passenger side between the flywheel housing and the block. I cannot see for sure where it is originating so after my next load I am going to pull the dog house and try to get a better view from the top to make damn sure that is where it is coming from before I pull the tranny.

Anyone who has replaced this gasket on an 871, 2250, or 2350, please share any tips, tricks or pics, I would greatly appreciate it.

Also, any danger in running it for a bit longer and just monitoring oil level like a hawk, until a more convenient time?

Thanks in advance!!
