metallic particles on oil drain magnet..

[daves66nova]

just changed the oil on my 89 gsxr 750. It's been a long time since i've changed the oil.I had a lot of metallic slivers and a few pieces that looked like clutch material.I believe the oil i used was 10w40 as spec'd. What might this stuff be?The engine was rebuilt around 55,000 miles ago.I just changed to 15w40 now.Engine does not get hot and i don't rev the snot out of it.

steel clutch plate material is always a possibility. same for tiny flecks from the tranny gearset and camchain.

a little fuzz on a mag drain plug is quite normal.

Have you ever opened up your oil filter to see what's being gathered there. I occasionally remove the paper material from the filter and open the pleats to inspect for glitter.

boraticus, dont know if that was posed to me or not, but i run a stainless steel filter that does better than paper.

Better than paper? Must be awfully fine mesh. How do you clean it? Just wash it in a solvent?

 

[sunruh]

it is very fine mesh 35micron filtering. and yes you back flush it in solvent.
fyi, it can cold flow more oil than the pump can produce. dont be fooled by its ability to filter that it will hinder flow.

here is what i use:

Filter up to 35 micron is not better than any paper filter I use.
My paper filters are in the high 90%'s for one time pass for 20 micron.

Doesnt look like scotts filter will even caputure a 20 miron particle.

Ive only used metal screen catridge filters on some ATV's and dirt bikes.

If I can screw on a filter I use a PureONE or WIX car filter.
