every time I change my oil, I leave the filter off after filling the oil tank back up. Start the engine, and let all the black oil run out. When the oil runs clean, shut it off and put a new filter on.
That way you have only clean oil in your scoot.

 

Take the rturn hose off at the oil tank and start your bike. This will get all the old oil out of the return line also. Just run it till clean oil comes out and then put hose back on and top off with oil.

 

That wasn't my question. The oil has been throughly changed 3 times in 3 weeks. The metal fragments will not leave. The next option is to split the jugs and I might as well buy a new engine if that is the case. I would like to do the flush if this is indeed a possibility.

 

What kind of bike? Is it new or did you get it used? How big are the particles? If they persist you may hve some sort of failure taking place in the motor. In which case you will need to tear it apart and investigate. It is still cheaper to rebuild your motor than it is to replace it.

 

I don't think I'd try the pressure trick. That sounds like a problem waiting to happen. However, before you tear the engine down, you might try a product called Auto-RX. It's purpose is to suspend particles in the oil and help the oil filter catch them, plus its a good cleaner. I've used it in my '90 Jeep, and I'm currently using it in an 96" S&S that has sat for awhile, to clean out the crud. Although the stuff is expensive (24.95 a bottle), it only takes 2 oz. per quart of oil. I believe the website is www.Auto-Rx.com. IT WORKS.

 

While Auto RX by all accounts does work at cleaning sludge out of motors, I have never heard anyone contend that it will suspend metal fragments. Best to e-mail Frank (Auto RX inventor) and ask before expecting it to do so. I think I will do just that as well. The cam bearings in my 99 TC-88 just disentegrated. While dealership replaced oil as part of warranty coverage I am concerned about shavings remaining. Will follow-up tomorrow.

 

Let it be known that someone on another forum ( www.bobistheoilguy.com ) said Auto RX will work to clean metal particles out of engines.

 

I've been a mechanic all my life(I'm probably been around longer than most around this site). My experience is not good news. That engine must be completely dissasembled. Anything short of that is trouble, and it will cost more. No flush has ever been able to clean metal from an engine. The stuff will lay in corners and come lose at the most inoportune times. Every time that engine goes around, it cost money. The cheapest way out of this is the best way. Shut it down. tear it down. clean every part(moving or otherwise). replace what ever is not right and reassemble with the best gaskets you can find. Sorry to say this but its the truth.

 

pause for thought.

what type of metal particles are you talking about?

Have you had an engine failure previously ???

Is there something currently wrong with the engine???

if you are talking a slight metallic look similar to metallic paint when you swirl it, it is most likely normal. if you drag your finger thru any lubricant that has been in an engine, tranny, differential etc.. it will have a metallic swirl look to it.

If you are talking about chunks, you are on borrowed time.

one of the things that gives pause for thought are that since most of the failures to any harley engine are in the bottom end where the bearings are, and a harley has a dry sump how do these chunks or pieces pass thru the gears in the oil pump? how come the pump didn't fail??

 

Doyall:

Sorry to hear about the cam failure. How many miles on the 99? I heard there was a possibility of cam problems with the 2000 models as well.

What kind of symtoms did you have prior to the failure?

Thanks

Magnet

Hi Guys,,,,,I am new on this board,,,,,regarding metalparticles in the oil,,put a magnet around on the incoming hose to the oilpump,,,,,and You can trap all the particles in the oil,,,,,and on the next oilchange ,,take away the hose without moving the magnet and clean it,,,,,all metalsparticles have being removed from the engine,

Best Regards

Then maybe we didn't understand your question.

Leaving the filter off & running the motor until clean will take most of them out.
The magnet trick works well, but I've heard most wrap the oil filter with a magnet. So when you take it off, the metal is inside the filter, not your motor.
If you're so worried about the miniscule particles, use this cold time to do a rebuild & have fun this spring.
Ride safe,

 

Prevention

Hi Trekker,,,,.naturally this is a good option,,,but if You have failure in the bottom end,,in my case broken crankpin,,and metalparticles in the whole system,,and You clean and rebuild everything,,,You can not be sure that all the particles is removed,,,therefore the magnet prevent any metal to pass the oilpump and the crankbearings and later reach the oilfilter,,this is to late,,therefore a magnet on the incoming oilhose catch the particles before the reach critical areas,,after the first oilchange the engine is clean and You can remove the magnet.

How's the big end?

That wasn't my question. The oil has been throughly changed 3 times in 3 weeks. The metal fragments will not leave. The next option is to split the jugs and I might as well buy a new engine if that is the case. I would like to do the flush if this is indeed a possibility.

===============================
If you are getting metal fragments continually in the oil in three weeks with three changes, I suspect that something is going out. I would consider that your big end is starting to bail out. Are there any suspicious noises accompanying your metal fragments?

 

A magnet will only help with ferrous materials. If the chunks you're talking about turn out to be aluminum shavings, then a magnet will do you no good.

Do the right thing: split the cases, clean it out thoroughly, put it back together and ride worry-free.
