a) I wouldn't have filled with the wrong fuel

b) I would have heard the knocking myself and done something

They are called COCKLINKS for a reason!!

You do realise, I assume, that you are supposed to adjust the CockLink until you get no red lights (what is the point of a knock sensor which needs the owner to adjust????) ........ it's a Random Light Generator!!!

The Subaru Knock Sensor can hear knock, react to knock and adjust timing in a few milliseconds ........ less than the time it takes to illuminate your CockLink light!!

Think, think, and then put your wallet away - these things are expensive pointless gimmicks ....... yes, OK, they make you look cool to the 14 year old girls and boys at McDonalds on a Friday night - but, to most people they simply say you are a right CockLink!!!

pslewis

......... and, when the Magnet itself comes loose?? What then??

i have to say i agree with pslewis here, the car already has a knocklink fitted and adjusts the timing accordingly.
so i dont see the point of a knocklink light either.

pslewis

Stu .... I know you have a personal interest in these magnetic devices - but don't let that cloud your thoughts about my Engineering ability.

pslewis

That's uncanny ...... if I did tell you then you would be in AWE of me!!

That's a cryptic clue by the way .....

Roughly translated as you have no interest in continuing your argument with someone who really does understand what he is talking about?
My questions are there to be answered and we can then discuss the topic further from there... fill your boots.

pslewis

EH?

That's not what it meant at all ..... it meant that you have a personal and financial interest in selling as many Magnetic Sump Plugs as you possibly can - therefore, oddly, your 'Engineering Degree in the HydroDynamics of Fluids' may be subject to some spin.

I'm interested to hear what particles you think will pass through the Subaru Oil Filter - a diameter will do.

And then, what diameter particle could do damage to the engine .... again. a diameter will do.

Also, where has this Ferrous Particle come from? The bearings are not Ferrous (the main wear in an Engine - that's what they are designed for).

I'm not disputing that this magnetic sump plug will attract Ferrous Particles which come within range - what is the range of the Magnetic pull on these? 50mm maybe?

pslewis

Interesting note on EBay about these items:-

I quote directly:-

"Dear Ebayer,

Before considering purchasing one of the above please take a couple of seconds to read this advice.

For those who have a limited knowledge of cars, the sump plug is esentially the bolt that screws into your oil resevoir under your car. This is the bolt that is unscrewed and taken out to drain your cars oil before replacing.

Why buy a magnetic one?

Many sellers on ebay sell magnetic plugs/bolts. Claims are made that harmful metal fillings that could damage your engine are attracted to the bolt, thus ensuring the fillings don't get circulated back into the engine itself. While I'm sure it does work, ask yourself the question - why do I have an oil filter?

Why not to buy one!

To be honest, they wont cause your car any harm. But before paying over the odds when a standard 'Partco' style part will do - bare in mind that any harmfull metal fillings or debris that could be in your oil will be picked out by your oil filter - that's what its there for.

One guarenteed thing that will help prevent your engine being damaged is to regularly change your oil and your filter"

David at API - very highly regarded on these pages and experienced in Engine rebuilds - shares the very same opinion as EBay ....... and as I do.

I have no axe to gring one way or the other - I have ZERO to gain whether people fit them, or not ..... I am simply sharing my many, many decades of Engineering Design knowledge.

So your best engineering answer to my questions, is to rehash my own questions and ask me to answer them myself, for you?

And you then go on to say the main wear items in an modern engine are its bearings? An engineer would never honestly believe that, so I am not really sure that further comments are worthwhile as your obviously, as people keep telling me, just on a wind up. LOL

pslewis

Hmmmmmm, I didn't think you would be able to answer!!

Happy Selling

Evolution Stu

Yep, been there and done that, as David originally thought all the moving parts were made of alloy IIRC. I suspect he has since changed his opinion... if you search, you will find the topic with he and I discussing that very thing.

Evolution Stu

Your as transaparent as glass this time sadly mate, you hoped I woudl answer for you and you failed.

lets face it... one of us writes technical automotive articles and runs both a well established tuning company and a well established remapping brand for a living and the other is well known for his internet trolling... I guess people will make up their own minds which one is likely to be correct.

pslewis

He choose not to argue with you - that's all.

Being an expert on these devices we look to you to provide answers ... I suprised you are struggling to oblige, in all honesty.

I assume that you have heard the term 'Wash Off'? Where the build up of Ferrous Particles, if gathered on the plug, wash off as a larger particle (these particles have been magnetised, of course).

Would you want minute, non dangerous, particles remaining in the oil suspension - OR, to have magnetised larger particles drifting about collecting ever more particles?

pslewis

If a magnetic plug is to attract contaminant, that contaminant must pass very close to the magnet. Particles don’t have to be too far removed from the magnet to negate any attraction, greatly limiting magnet efficiency.

You once referred to David O'Brien at API as a "hobbyist", didn't you.

Evolution Stu

If you answer the original set of questions that I raised in direct answer to your previous comments then I will gladly continue the discussion as much as is required, until then, enjoy your trolling as I have no interest in wasting my time putting points to you that you wont answer, as has proved to be the case so far.

pslewis

Can't answer the wash off question either ... bad show.

You are, after all that ***** waving, the undisputed master of the Magnetic Sump Plug - I'm shocked that you cannot give me the diameters?

Clue ..... it will be a number with the word Micron after it ... probably between 5 and 25 at a guess - but, I'm not the master - that's why we ask you.

Anyway, my Design skills have kicked in .... how about dismantling an old speaker, taking the magnet, and attaching it to the Oil Filter casing? That would do a decent job, wouldn't it?

We could market it as a 'Magnatron Filter Triple X Rally Spec Ferrous Particulate Attractor' ............ should sell in shed loads!!

So your a part in the war machine that robs us tax paying brits of a nuclear threat that doesn't exist? And even if it did it would all be over before you'd have a chance to fire back?

Well.....****ing.....done

I would have been far more impressed with NASA to be honest.

CASD ... or Constant at Sea Deterrent is extremely good value.

And, as for it being too late to fire back, that's why we do not launch from the UK or any of our ground bases!

We launch from somewhere in the Oceans - no-one knows where we are ..... rest assured, if someone wipes out your family, friends and loved ones - we WILL destroy them.

I'm sure that, for a fraction of the cost of chavs on the dole, you would agree that is amazing value for money?

dj219957

Nice idea Pete, ive got some old alba 12 inch hi fi speakers, will they do? Do I put them one on top of the other or one on each side of the filter?

pslewis

The 'Magnatron Filter Triple X Rally Spec Ferrous Particulate Attractors' can only be made from SONY Speaker Magnets ..... I'm afraid ALBA speakers, as everyone knows, have their Ferrite Molecules arranged in a West/East configuration.

SONY have their Molecules arranged in a North/South orientation .... thus attracting more dangerous ferrous particles away from the vital moving parts of the engine.

We could market the ALBA ones as a cheaper alternative for the Chavs ..... call it a Super version and we will mop up!!!

The points he (Pete) has raised have not been answered with any conviction. As someone sat on the fence I would certainly not be rushing out to buy a magnetic sump plug on the basis of this thread. Stu@Internet Brands has a vested interest in these plugs so can't offer an objective viewpoint. Furthermore none of the respected tuners/garages openly recommend these plugs. Infact David@API categorically stated these plugs are a complete waste of time and money. Go figure.

Certainly didn't make a fool of myself and l have been misquoted - again -.

Most wearing parts in an engine are alloy of some sort, And as such are unattracted by a magnet. They are made of soft metal [ pistons and crank bearing surfaces ] so as to take the shock load. The heavier parts are protected by the soft parts, when the soft parts are doing their job right.

Any particles that do erode from steel / iron moving parts are small enough to get trapped by the oil filter.

Larger particles will get attracted to a magnet - but large enough particles to do damage, that get on he magnet, mean the engine has already failed anyway........... Too late!! she cried.

By all means buy a magnetic drain plug it cannot do any harm, except to your bank account. BUT it isn't going to do what you think it is going to do.

In a transmission, where iron and steel parts impact on each other you would be mad not to have a magnetic drain plug. But where metal parts that are designed to wear slowly and are made of alloy and don't impact on each other are fitted, the need is far less.

If an explanation like that means I make a fool of myself Matty then I am happy to be considered stupid as the day is long.
