Hello Everyone! I have had the following oil leak for about a year now, its very slow but its time to fix it. I regularly check oil level and do have to add some between oil changes. The best way for me to ask the question is by showing the picture..I cleaned the area where I suspected the leak and with the engine running it is clearly coming from the joint of these two parts that the arrow points to. I'm no mechanic by any means, but my father-in-law was a Honda mechanic and will be helping me fix it. I would like to know what gasket/seal/part I need to fix the leak? I have a few more photos if needed. Any help would be greatly appreciated!
oops....please bare with me on the pic

Thanks
