Not sure what you really mean mr66, from the pic I think you talking about the bolts holding your auto in. You can tighten these up as much as you like and it wont fix the leak, you could take one of these out and it wont leak. From the pic it looks like its running down the block and if its not from the rocker cover try your sump bolts(all the overhead ones) , dont overtighten them though. Hope this helps Shane.
