We've been following this over on duramax diesels since the first video posted. Gale Banks always twists fact to say his stuff is the best. The magtech covers have been around alot of years, when was the last time you heard someone complain about premature gear or bearing failure caused by lack of lube while running one.
There is already one company that makes a stockish shaped finned cover (pictured in 1st video) he says its junk because it has a small reservoir on the bottom.
He will release a cover within a month of the final video with scientific proof of how it's the only one in the known universe that's built right. Just like everything else he makes.
