I had a rear main go out on a new 5.3 LS(mild build) that was less than 1k miles old. Replaced seal added Metco breather, no issues since.
If you don't want to try the Metco breather, One thing you will want to make sure is that your breather lines are all upgraded to -10 and routed correctly for the MM wild can to vent crank case pressure efficiently.

That catch can breather depends on the lines going to it to be able to manage the volume of air in the crank case. Catch cans and their long small diameter hoses likely offer much more restriction and hold pressure in the system longer.
This breather is a large 1" size opening to the crank case with significantly less pressure drop. It can handle large volume quick impulse crank case pressure events much better than any catch can could (shifting, snapping off throttle, etc). When vacuum returns to the crank case it seals off the vent with the floating disc.
