VAC oil leak from head

I was gonna replace head gasket, etc. cause of an oil leak. On closer inspection, it looks like the oil is coming from the stud that is located on the right side (for a spark plug cover?). I moved the stud and seems to be loose. Also, there is some silicone where it looks like someone tried to stop the leak. I am thinking of pulling the head anyway and see if I can replace or plug where the stud is-maybe weld. Has this happened to anyone else and do you have any suggestions for a repair?

I'm not sure about the VAC heads, but the later tractors can be sealed around those push rod tubes by removing the head, pressing out the tubes, and replacing orings that are between the tubes and the head casting both top and bottom.

The push rods go through the tubes on side of the head. There are 8 of them and they are pressed in and can leak oil. You could try leaving the tractor set with the stud removed and then clean the hole with brake cleaner let dry and install the stud with gasket maker.

Today's Featured Article - Two-Brush Generators - by Chris Pratt. Whether for product liability or because the aftermarket parts and labor business is lucrative, this concept is disturbingly prevalent. Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit ... [Read Article]
