Magnetic Sump plugs - Hype?

Recommended Posts

Judging by the amount of metal I get on my other cars oil drain plug magnets, it must be better than having the bits floating round in the oilways.

 

I think Gavin L was trying to source some a while ago..

 

I would have one like a shot if anyone can find one for the MKIV.

What about the two 'newer' things ? ? ?

 

the magnetic 'insert' that screws between the FILTER and BLOCK ? ? ?

 

and,

 

the magnetic 'lump' that just sticks to the end of the filter ? ? ?

 

same ideas as plug, just going a bit more 'overboard' ? ? ?

I work on aircraft and used to work in the early failure detection side of things. We use mag plugs to monitor the wear in aircraft engines and gearboxes. Its a relatively simple process. Extract mag plug at set intervals ie 3000 miles for instance degrease said mag plug with whatever degreasant you can lay your hands on (we use petroleum ether but white spirit would probably do). Using clear sticky tape dab the remaining metallic debris onto the tape in a 2 pence piece diameter size or smaller. Then measure the ferrous strength (difficult part if you haven't got a debris tester lol) and record result. Stick in a book and watch the profile grow. If there is a problem developing then it will show in an increase trend. If you are really technical you can send the debris to a lab get them to scanning electron microscope it, send you the material spec of debris and then you go to manufacturer of engine and ask em what bit is made of that metal spec thereby knowing which bit is getting buggered. With aircraft stuff we can generally figure out which component within a gearbox or engine is letting go reducing our down time for servicings. You wanna get mega technical and you can sample the oil send this to the lab and they will spectrometrically analyse it (burn the stuff and see how much metal there is in on a parts per million basis) and build a concurrent profile next to your mag plugs.

Tedeco make all our mag plugs so its possible they may be able to fit you up with summat.
