hello everyone, new to this site, hopefully ill be using it alot and posting threads. i have a question. my k5 blazer has a small slow leak of transmission oil coming from one of the bolts on the transfer case. i tried cleaning all the underside and tightened it, still leaking. what am i gonna have to do? is it a gasket or just too full? anything can help. i can post a picture of it if needed.

thanks

 

pictures always help. is it the drain bolt or a case bolt

 

case bolt. only one. ill get a pic up today.
