chevy caprice classic: how do I stop the oil returns from clogging

This answer was rated:

how do I stop the oil returns from clogging up every 2 or three months on a 1992 caprice classic 5.0. It seems to be an ongoing problem. Is there any cleaners to flush the returns?
Try adding 3 quarts of marvel mystery oil and two quarts of regular oil, then run the engine for about 5 minuets.Drain and just do a regular oil change,that should correct your problem.
Do you still need more assistance?
