i just got rid of my oil pressure tach so i was putting the stock sensor back on. its been a while since i took it off but i wasnt sure how far the screw it in. i have heard that if you tighten it to far you can crack your block. but since its not screwed in all the way i have a minor oil leak. so should i go ahead and screw it all the way.

 

Id say there has to be a torque spec sheet on this site with that on it since its on the block, if not then just tighten to where its as snug as it gonna get without over tightening it, cause you can always tighten it a little more and see if it keeps leaking. If you over tighten the first time and crack the block then your fucked basically
