Oil leak from the lines. Need Help.

[killaz]

Hello all, I have a 2013 Silverado 1500. This thing has had an oil leak for a bit, and was able to track it down. The 2 lines right above the front driveline held in by 2 10mm bolts. That gasket was seeping some oil. Pop the 2 bolts out, add the new gasket, go to tighten the 2 bolts and they will not get snug. now my small oil leak is a larger oil leak. Any advice? Can I block it off and do something external? Looking for options 

thx

Pull the bolts out one at a time and look at them.  See if the threads on the bolt have stretched (this has happened to me for these bolts) or if the threads they go into have stripped out.

 

Then either or both replace the bolts and/or helicoil the threads.  And use a torque wrench to install the bolts, they don't need a lot of pressure to seal the connection.
