I'm having a hard time keeping bolts in that hold the exhaust flange on the turbo from backing out. I was debating putting a dab of JB Weld on the corners to hold them in. I have the big bolts that hold the turbo to the manifold tack welded on but I can't do that these little bolts because if I wanna take the exhaust off later I won't be able to get to the welds with a grinder or impact wrench to break them loose. So what do YOU use to keep those bastards snug?
