    Curious if the Magnetic Drain plugs do anything?

    I last changes the engine oil and transmission gear lube the weekend before the Dragon and installed the drain plugs from Mr Dimple. Approx 4500 miles later I changed both fluids again to see the effects of the magnets.

    From the engine.

    From the gearbox.

    I'll do my best to change the fluids again at our next Club DIY day to see what the magnets have picked up.

    Thanks to Blind Dog Daddy for the images.

    Might have to swap out my fumoto, although I wonder how much of that stuff washes out anyway. Maybe I'll filter my next oil change, see what I pick up, need to change it in the next couple of days anyway (and the car is just off a track day).

    Those things reusable, or do they need a new gasket or anything with each use? They look much better quality than the OEM plug....

    I did change the crush washers.

    I'd imagine most of the bits are flushed out with each change but IMHO the magnet grabs the stuff and keeps it from floating around during engine use. Probably makes life a little easier on the filter as well.

    Once you shut down the engine most heavy metal particles will settle to the lower compartments or area's of the engine. A lot of times once they come to rest they will remain there even after changing oil. Even the engine running sometimes will not lift them back in the volume of oil to circulate through the engine hopefully later to be caught in the filter or the drain plug magnets. A oil changing trick is to use a quart of ATF in a warm engine prior to changing the oil. ATF is a high detergent oil and will clean better then engine oil and will help increase flushing during an oil change. Driving a short distance with it in the crankcase will in no way harm an engine.

    Impressive.......but what about us guys that are using the OEM oil temp sending unit. What would be the best alternative?

    *Drill and tap the sump (pan). Change the oil more frequently?

    * The best way would be to drain the oil and weld a bung to the sump. Unless to know exactly where the thicker casting of the pan is you may not be able to tap enough threads for a secure hold on the drain bolt.

    There are few that have had the pan off enough that may be able to give a good location for just drilling and tapping?
    George at MINI MADNESS may be able to give some good information on this as he has a modified MINI pan that he offers.

    Kinda what I thought, but as you stated I have no idea where a good place to tap would be. How far below the pan would this plug extend? Would hate to rip it off hitting a curb at the track.

    I currenty change the oil about every 4-5k.

    6 speed primary is m-26 x 1.5
    secondary m-16 x 1.5

    The engine is m-20

    The rear differential will have a new model available in about 7 - 10 days.

    I believe my oil drain is already magnetic. From the ones I've removed on the R160 rear ends, they are too. Wonder how much diff there is

    Yes they are.
    The ones from Magnetic Drain Plugs are 150% stronger then the oem units. I also think that they have a larger surface area then the oem?

    Its good to see the results. I've sold several of these and been installing them with alot of oil changes here at the shop.

    R53 magnetic drain plug
    R56 magnetic drain plug. This one we really like cause it gets rid of the silly allen stock drain plug.
    I've got the trans ones too, but not on the site yet.

    I hear ya, too many things to plug into too few spots. Drilling the oil pan is not my first consideration, but our options are definitely few.

    Way,

    Do you have any recomendations for an alternative location for the oil pan one? A thick area on the pan?

    After talking to a a friend that was king enough to measure the thickness of the MINI oil pan there is no better or good location. The pan is the same thickness along the bottom and will not give more then 4-5 mm of threads. Although this may be enough to hold a drain plug the better solution is to weld a bung for the drain plug.

    The one on the left is a specially coated pan.

    ^Yeah, I've had the oil pan off a few times and I looked for a spot to drill and tap a temp sender. No real good places, and I have no means of welding anything.

    My oil temp sender is just in a special drain plug, the wire has a blade disconnect so that it wont twist too much and snap.
