I got a replacement magnetic oil drain plug and I'm changing the oil today. A forum member was selling them a while back...
Couple of concerns/questions...
The one I have contains a 19 mm bolt head on it, and it sticks out about a half inch. The factory one is flush with the oil pan. Should I be worried about this? I see no bottoming out scrape marks on the oil pan.
Next, it has a black plastic gasket, not the aluminum one that should be swapped out each time. Should I use the plastic one or an aluminum one?
Last, the magnet is very securely attached to this steel bolt, probably with epoxy or JB weld (can't tell if it is screwed into the bolt as well or not). Now if I'm thinking right, to attract metal to the exposed end, the glued end is the opposite polarity, pushing away from the bolt, right? That gives me rise for concern. What if the glue gives way and that magnet takes off and finds some steel to attach itself to in my motor?
So, here are THREE questions for some knowledgeable about these plugs... Please don't post a best-guess if you don't know much about them or their use. This is my motor we are talking about here, not a tire preference or something else that's quite subjective.
