DIY - 'Magnetrap' - Oil Filter Magnet

[TitanRev]

If the magnetic is strong then it will catch any metal that flows by. I have cut out used filter on my 206 before got some fine sand like stuff stuck at the oil filter wall where the magnet is attached. The magnets on HDD is different from normal magnet where the magnetism is very much stronger.

HDD hunting is ON! xD

hmm i think i still have some spoilt hdd lying around, muehehe

Wah! like that means those still pass the filter element....

Vr2, I cant be sure but if the fluid is under pressure sure the flow speed is high and you know oil filter is mainly made from paper element. If it's something sharp could cut through the filter element. I can't verify this but just my thought.

If we change the oil filter frequently and don't delay the service interval, I guess not much metal impurities will go though the filter. My 2 cents..

Drain plug metal filing stick to it is good, then can clear them out, but necessary for the oil filter? Isn't the filter suppose to do the job?

I put them on both location. No metal pieces on eo oil drain plug, more of a metal dust but inside the pry open air filter(God knows how hard is it to manually cut the air filter in half using steel cutter), there are mixture of tiny sand and metal dust.
I forget to mentioned, I have done it on gearbox too. Guess what, thick yellowish metal dust on transmission fluid drain plug. Must be my sister changing gear without fully engage the
clutch .

More aye and less nay .
Yes : As the material of eo will degrade and become less effective after certain usage / period, service on time will avoid the build up of metal impurities inside. Reason for 5k - 10k service interval depend on eo type. Being a lousy driver, I usually change eo about 0.5k earlier from the service interval.
Nay : Most of the damage to the engine part happened during cold start where the cylinder, piston and whatever moving inside are not properly lubricated yet. Reason why I stay away from buying a lady driven car as I have seen many start their car and rev away. Old people tend to rev their car '99' to reach the optimum temperature in fastest way...

I think you mean oil filter?

This one sure change with oil change....

Actually, why on earth are there so much metal shards in your engines la? Mine was rebuilt so I have an excuse. You guys probably have fully run in engines and I don't see how you can get metal pieces floating around your oils.

Anyway, I put my magnets on my oil sump (inside). Everytime I'm in the mood I take out the sump tray and hey presto, the magnet is still there covered in metal filings. Now when I think about it, it's probably not a good idea to have a huge block of metal inside the engine hor? Especially if the magnetism loses its properties.

Oh shit. Ok I have something to do this weekend.

Hmmmm...to be frank, I've never warm up my engine in the morning. Just start engine and go.

Engines have optimum operating temperature range and the best and fastest way to reach that temperature is to drive them right away. This way, all the components reach optimum temp at the same rate. Idling too long to warm the engine up means the components are operating below optimum temperature longer so they'll exhibit more wear.

The key here is not to overstress the engine early in the operation, i.e to slowly build the rev as you go.

I have a habit of letting the engine idle for 3-5 mins before moving slowly and build up the revs... At cold start the idling for warming up will come down and thats when i start driving.

How big is the magnet? If big, you are replacing the space meant for the engine oil....

I start the engine, let the oil circulate for a while, reverse out then come out to lock the gate then drive slowly for 1st km or so....

I always start engine and let it sit at least 3-5 minutes while I take stuffs to put in my car and also open the gates. NO air cond too. Hate it when my friends or family member simply touch my cars.

i normally turn ac after +-30seconds the engine started to give small load for faster engine warmp-up....


why +-30seconds? because it was roughly taking that time for the engine oil to fully lubricating all engine area and the oil pump was fully primed up for its job...

I read through the whole of the OP but was unable to see anything related to how we can get the HDD magnets.. Did I miss something out?
