Started out my speedometer did not work. I googled and was told to take a 1/16 drill bit and turn by hand until clear. The clog was very hard so I had to use force on the vise grips I was holding the drill bit with. After getting about an 1-1/2” in, it cleared. However, when I pulled the drill bit out, it started pouring out oil. I suspect I punctured a hole on the other side of the tubing. Any ideas on how to fix? Could I possibly seal the hole with silicone to prevent leakage without causing further damage?
