Citroens and their stable mates Pergeot [I can never spell it     ] that I have owned have had them.

my concern would be risking a restriction in oil flow when something gets trapped in the magnet filter.


I have always prefered a magnetic sump plug

Oil filters are actually 3-5 microns these days as all the paper is made in two or three countries, then shipped out to OE and aftermarket manufacturers.

The purpose of oil is to suspend small particles as well as lubricate, the oil pump is large enough to cope with them and they are filtered out in the oil filter. Particles which  enter through the return hoses, or internal engine drain channels are the only ones which should be in the sump unless there is a problem with the engine.

I; from experience, prefer the in sump types as these remove many before they are pumped through the engine, this preserves the oil filter and prolongs its life, it also helps the oil pump by reducing any larger particles.

mag drain plugs in sump gearbox & diff are common still in most heavy trucks today
change the oil & filter often use decent oil is the best thing you can do foryour engine replacing diff & gear oils every year also aint no bad policy ! mg on filter wont do any harm although as has been said you wont know whats in the re unless you disect the filter (messy)!

just get a big powerful magnet and stick it to the sump near the drain plug.  

any debris in the oil will stay at the bottom of the sump out of harms way

Yes, Mimauk remembers more than he thinks! The old Minis used to have them, an inch long cylinder magnet in the drain plug. I remember draining the oil from one once and stuck to it was a semicircular crankshaft thrust bearing. The chap who owned the car was prone to a lot of bad luck and complained that the clutch had a clunk to it when depressed....that was the reason. He loved his mini though and thought it was one of the quietest cars he had ever owned. He changed his mind after driving back from the doctors having had his ears syringed.

paj's have magnetic drain plugs anyway... well mine did  

[REVOGEL]

Most Austin/Moris and for a shot time BMC upto app 65 had them my 65 mini [only car ever from new] had one I think.

I stuck a magnet on the fuel tank drain plug.. or close to, just to catch any rusty bits from a damaged fuel filler pipe (fixed now) but left the magnet there !!  

[hutchy]

a lot of the kia,s and hyundai,s have magnetic plugs now....years ago you could buy a gizmo that went on the oil filter that had magnets in it...i just thought it was a blag to make money from people daft enough to fit them,but they sell them for fuel lines now apparantley saves fuel god now,s how i could do with the whole line being full of magnets

[Rob546454]

Quite a good idea to be fair. Always liked to use magnetic drain plugs but they are only small. Its easier to remove them too as you don't find yourself dropping them into the oil tray.

I have magnetic sump plugs on my type r..one on box one on engine .

This thread has reminded me of am engineering shortfall that I am trying to resolve so attention if I may.

I rebuilding a 2.8 4m40. The reason for the rebuild is that while offroading the vehicle entered a steep decline, causing oil starvation. Resulting in some rather worn big end shells.

Look at the design; how the sump overhangs the crankcase into the timing case. The timing case is quite a void, at a guess I would say you could loose at least 2 litres of oil in there.

So when the engine was on the incline, the oil drained from the sump and flooded the timing case. Not so bad for the timing gear but bad for the rest of the engine when the pickup pipe no longer contacts the oil.

I am looking for a solution, as is someone else. The mention of helicopters prompted this, as no doubt the aviation industry has a simple solution for this, as opposed to something like a dry sump which is a bit unnecessary.
