Just wondering if anyone else had seen this issue and what was the cause and cure for it. I have some ideas but just wanted to make sure that my thought process is sound. Below are a couple of pictures of where the leak is coming from. It only occurs when I use the 3 point and looks to be coming from a place where a vent for the casting was located maybe? I thought about drilling and tapping the location where the leak is to fix it with a plug. Everything functions fine and it only seems to do it when lifting. I have a video but I don't think I can post it on here due to size so below are a couple of photos. comes out right at the end of the black line that says "here".

If anyone has seen this please chime in and let me know if you have a better solution. Thanks!

Thanks Ya'll. I usually check jd parts catalog first but didn't this time. It is flush with the surface which made me think it was filled instead of a plug. I now feel dumber for asking this question. A lot easier fix than I originally over thought.
