Alright, in a bit of a bind here. After changing the oil, my oil pressure sensor wouldn’t go out, so I pulled the sensor. When putting it back in, I cracked the crankcase. When looking closer at the crack, it looks like a stone had weakened the area. Not an over torquing issue. I drained the oil and had it welded. Leaked after welded so I put some Teflon tape on sensor. Cracked again. Now I have been using JB Weld and it doesn’t seem to work. Anyone have any ideas on how to fix without a new crankcase and engine rebuild. Thanks.
