I will speculate. If the joint surfaces did not pull apart while the nuts were off or loose you will not have a leak. If you didn't excessively overtighten the nuts and move the joint you won't have a leak. However, if there was enough residual stress in the joint when you loosened the nuts or the engine running loads moved things when the nuts were loose you will have likely have a leak. If you overtightened the nuts and moved the joint you will have likely made a leak. Who can tell? I believe your best course of action at this point is to loosen the nuts one at a time and retighten them to the correct torque. If a seam leak remains you'll need to split the case to fix it. Good luck . Jim
