This may sound really stupid but do you guys think i could jb weld a magnet to the end of my oil drain plug? Im wondering if would it would adhere to the plug thats been soaking in oil? Or would the hot oil temp and heat cycle effect it?

 

Honestly your best bet would be to stick it in a drill press and bore the end and press fit it into that.
I just would not want to risk it.
I mean you could try it, worst that could happen it winds up in the pan, The pick up has got a screen on it to prevent it from pulling such things in but I would prefer to not test mine.
As much as it seems a good idea, I'm sure frequent oil changes will keep the engine running well enough.
I don't recommend the Mr.Dimple plugs because they seem over priced, I have not used one. and I don't hear good things.

 

They have those janky magnet oil drin plugs on the eBay, and I asked mini about it one day. They laughed, said they've seen those, and seen them break off in the engine!

Like Colin said, as long as you change your oil and filter, it's really unnnessesary...

Janky... That's a funny @ss word! Hehe

 

You can buy this. http://www.drainplugmagnets.com/.

i would rather do that then have my DIY JB weld magnet break free in my oil pan.

I don't know if it works or not, but I wouldn't call it Janky. I think a 10 year old would have a tough time pulling that magnet off the side of the oil pan. It is really strong.

Dealers make money repairing cars not preventing breakdowns.

 

a ten year old cant heat it up to 200+ degrees and back constantly breaking down anything in there. being inside a engine is a harsh environment.

 

Bought a magnet oil pan plug at Oreillys 3 years ago for 5 bucks and no problems.

Yes, but the Big question: has it actually captured anything!

What about slapping a decent sized magnet on the bottom of the oil pan, and just leaving it forever. Wouldn't that trap particles just the same?

 

Yeah I'm not expecting it to act like a filter or actually do anything but its more just for my curiosity when doing oil changes. And I'm not going to spend money on something as simple as a magnet pressed onto a plug so I thought I'd see if I can make something similar. I think if I just tossed a magnet into the pan it would end up getting thrown around and I'd be worried of little peices cracking off

 

I get the reluctance to pay money for a rather simple concept, but in the end you have to look at the risk involved in saving $5-30 (less the cost of the JB weld and magnet) vs. having the bond fail and have both a magnet and pieces of the adhesive floating around in your oil pan.

 

If you need to replace the drain plug and want a magnet, buy a proper one. Usually, transmission plugs are magnetic (auto at least), but there's more stuff that can contaminate the oil with metallic particles, clutch packs, gears, etc.

 

You would have to GLUE it to the pan....it is CAST aluminium.....and having to conduct the magnetism through another layer would make it less potent.
Most any magnet used in this type of application is usually a RARE-EARTH magnet...
You can buy them at radio-shack, online, or even harvest them from old hard-drives.
Then the issue is how do you get the shavings out....vola,,,the plug!!

 

the trans has a magnet in it stock, it never really collects much other than metallic fuzz.
I really would not worry about it.

 

When i was servicing my supercharger I replaced the plugs with magnetic plugs from WMW. Mostly did it out of curiousity.

As for the oil pan, not to sure a small magnetic drain plug would be strong enough to capture anything given the volume of the oil pan. But it cant hurt

 

I purchased them from advanced for a few of my cars and they were only a few bucks. The thread on the mini is m14x1.5 if you grab one.

Here's an article that came out from blackstone on them

I think they're belief was it only draws out the iron in the oil and thats usually not the issue with engine failure and non ferrous metals make up most of the metal that floats around. I remember after building an engine in my evo there was a lot of metal on the first oil change but only a very small amount every time after. It was always a good piece of mind for me. usually from the factory most manufactures only use magnets in transmissions, rear ends and transfer cases were oils are used for extended periods and the metals contacting each other are ferrous metals.

It can't hurt to have one and certainly may make you sleep better at night for a few bucks, but I don't believe it's necessary or more manufactures would be using them in engines.
