Well it won't help with the aluminum chips. It will get any burrs that may come off the crank and bearings eventually.

The magnet on the drain plug is there as a secondary "catch-all" for (heaven forbid) large ferrous objects that may end up in the crankcase and hold them until the next oil change. During an oil change it's normal to occassionally find very small filings and / or metal dust (so to speak) on the plug. The engine uses a pressurized oil system and all oil supplied is filtered such any debris in the engine case and sump should not result in damage from dirty oil being supplied.
In saying that, what does take a beating are the two oil pumps. Any debris in the case has to first pass thru the scavange pump then the main oil supply pump to then be passed on and collected in the filter. Of course if these two parts become damaged from large debris then... well you can easily figure out the possibilities.

Yo Alien,
We're both on the same page here. You're also right that some of us (me mostly) didn't read backwards far enough and think 'bout what and where you where coming from.
I've always admitted that sometimes, which is most of the time, I'm just smart enough to be dangerous.

No problem, I actually don't let any of this get to me. Its all in fun and a discusion between people with a common interest (motorcycles)!
I have said this before, your opinion is worth no more and no less than mine. We are each entitled to one.
That being said if scr103 would like some additional chips for a quicker break in I would be more than willing to help him out if this is what he truly believes, I am just trying to help here

I read the whole thing. Should have put a in my reply. I know you know better. LOL
BTW I work in a machine shop and have access to alot of very good metal chips. They break in our tools everyday. We have mostly Inconel, Titanium and Stainless. If there are any you need let me know. You won't have to worry about the magnet sticking to those either.

Hmm, well, not exactly. Almost all piston aircraft engines are broken in using a straight weight mineral oil (non-additive oil). The use of mineral oil allows the rings to seat. The mineral oil is kept in the engine until the oil consumption stabilizes at which time the operator's oil of choice (almost always an ashless-dispersant oil as opposed to a detergent oil) is introduced.scre103 said:
I have never heard of metal particles doing anything other than harm in a piston aircraft engine (or any other engine for that matter).
It is kinda interesting to note that, to my knowledge, there are no FAA approved straight synthetic piston aircraft engine oils. About twenty years or so ago Mobil introduced a Mobil 1 synthetic aircraft oil. Man, operators almost p1ssed themselves they were so excited. It sold like hotcakes. And then the problems started. It was an absolute boondoggle on Mobil's part and the oil was quickly withdrawn with a ton of lawsuits on its heels. The fact of the matter is that synthetic oils do not do well at all in any application where they have a tendency to get "dirty" relatively quickly (mainly from combustion byproducts). Piston aircraft engines have relatively large tolerances in the cylinders and the oil does come in contact with a lot of combustion junk. There are some semi-synthetics for aircraft engines and lots of folks swear by them. But the pro-con argument is just as passionate there as it is here.
Hehe, I kinda get a kick out of seeing all the debate on these oils. I don't think it makes a hill of beans difference what kind of oil you use as long as it is a quality oil, you use the proper weight for the conditions, keep the level where it should be and change it often. Hey, if it makes you feel better buying a high priced oil then go for it. You can't please everyone so you might as well please yourself.
Now if you really want to see a gold-plated mess try putting a detergent automotive oil in an aircraft engine after it's been run several hundred hours with an AD oil. Take off after doing that and even the most brazen atheist will feel the need to pray!
