Magnetic engine sump plug
I am thinking of fitting a magnetic sump plug to my 1275 sprite engine that has recently been reconditioned and fitted to my van. I found one on ebay that states that it has a 5/8 inch UNC thread. Does anyone know if this is the right size for the job?
Re: Magnetic engine sump plug
Can't see the need myself........ and sorry - no idea about the thread.
Re: Magnetic engine sump plug
My wifes mini sprite has a magnetic sump plug as standard fitment (auto box and torque converter shares oil with the engine!)
Dont know what the thread is though and it may be a different plug on the mini
You could ask the usual mini spares suppliers.

Re: Magnetic engine sump plug
Oh yes - it's an essential on a Mini - with gears shedding shards almost constantly! But no need on a Minor.

I highly doubt that the thread is UNC. Most all sump plugs are fine thread of one sort or another.

Re: Magnetic engine sump plug
The Mini one goes into the alloy gearbox casing - it very probably IS a UNC thread - although I can't confirm its' size. The Minor one is certainly NOT UNC!!!
Re: Magnetic engine sump plug
Perhaps you could get 1 or 3 of those really strong little pill magnets off Ebay and epoxy them to the bottom of the existing plug (Ie the outside not inside) to make it magnetic

Re: Magnetic engine sump plug
I don't think that would be very effective. Have heard of strong magnets on the oil filter but probably highly debatable.

Re: Magnetic engine sump plug
Magnets ex hard drives seem to be popular on the filter casing on Minis - but really don't see the need on a Minor - but - can't do any harm!

Re: Magnetic engine sump plug
A "pill" magnet on the inner end of the sump plug will work as intended and you will be able to see how much it has picked up every time you do an oil change.
As Roy says, it wont do any harm.
I've got a hard drive magnet on the sump near the drain plug as I've got lots laying around* and it can only do good.
The catch is that I wont be able to tell if it has without removing the sump.
*Another use I intend to use one of these magnets for is to put some timing marks where I can see them standing up.

Re: Magnetic engine sump plug
Very old thread this but the OP's question was never answered. I am going to do an oil change soon and I thought I would fit a magnetic sump plug just to keep an eye out for unexpected engine wear.
The answer for an A-series engine that does not share oil with the gearbox e.g the Minor (but not the Mini) is 1/2" UNF (20 TPI). Broadly speaking, there are 2 options; a standard magnetic sump plug (which ESM and Holden sell but currently out of stock) or a "Gold Plug" which is considerably more expensive but has a very strong Neodymium magnet (Gold Plug AP-01).
Might be of some use to someone searching threads one day.

Re: Magnetic engine sump plug
:I have fitted the ESM one. Very worthwhile if you want your engine to last

Re: Magnetic engine sump plug
Links to said 'Gold Plug' and the ESM magnetic plugs below.or a "Gold Plug" which is considerably more expensive but has a very strong Neodymium magnet (Gold Plug AP-01).
Best wishes,

Re: Magnetic engine sump plug
Would one of these work using the standard sump plug?

Re: Magnetic engine sump plug
You could drill the standard sump plug and epoxy one of those magnets in? It would be much cheaper than a "Gold Plug".Myrtles Man wrote: ↑Wed Jun 14, 2023 7:38 pm Would one of these work using the standard sump plug?

Re: Magnetic engine sump plug
I made one for the gearbox, drilled a 8mm hole in the original plug then epoxied a 8mm magnet in the hole and peened the edges over while the epoxy was still wet.
