Pressure Oil Tube Fitting leak

I have a pesky leak from this fitting that connects the engine to the oil tank. I've tightened this fitting once using a new crush washer but it has loosened again.

Is there a retaining compound that I can use? I feel the case material (magnesium) is worn and a little sloppy.

Those can be loc-tited in to the case. If the threads are very worn, you may consider JB Weld.

Ordered some Loctite 680 from McMaster
Should do the trick

If the Loctite doesn't work, I make extended length fittings for cases with loose or stripped threads.

What is twisting this fitting counter clock wise? Would it be the steel oil pipe? Do you have the good kind, which crosses under the bell housing and comes out by the end of the engine oil cooler? Is it attached there as per factory? Could you fashion some other support so the weight of this pipe doesn't loosen the fitting just that little bit?

Very clever. If it works loose again I may give you a shout. A good aftermarket part would be a -10 or -12 hose from the case to the tank IMO.

I suspect the attachment on the right side was unbolted at some time and caused the fitting to work loose and wear the threads in the case. Right now the fitting is coated with the green Loctite and torqued in with a new crush washer.
