Years ago, I used a magnetic oil drain plug with the hope of catching small metal bits in my non-filtered T1 engines. It worked, there were always some real fine, kind of powdery black particulate.
Recently, I re-engineered the oil cooling in my 2110 and removed the comlete oil filter. I had not used a magnetic plug since the engine was new - just the filter. Much to my surprise, the magnetic drain plug is too long and would not fit because it drives right into the bottom of the screen base! Even with thick gaskets on both sides of the screen there was about 3/16 inch clearance between the drain plate and screen gasket.
A week ago (maybe 100 miles, about 5 runs) I put four "super magnets on the drain plug plate. When I dropped the plate for my regular oil change there was some particulate. Not a lot because the engine is still young.
These things are strong! While removing the plug, it slipped out of my hand and one of the magnets grabbed that little sucker and held it tight against the plate - whap! Neat little side benifit. There is no bump that will shake these off.
Any comments?
