Good vid ..to bad i didnt see it earlier ,,I scotch 2 of my cylinders with PB blaster but the engine is on a engine stand ,,Could I flip the motor upside down and spray the cylinders with brake cleaner to flush it ?
How does a material that is softer than any bearing in the engine going to damage to said bearings if the bearings are harder than the aluminum oxide? To scratch or damage a surface the material has to be of equal or greater hardness.
Do you think I can get away with the scotch brite I used to clean off a intake manafold gasket surface, I tried to get all the dust out but there is still some left in the runners, rookie mistake I know I should have had something in the hole to prevent that
Okay I tried my best to follow I’m not completely finished with the video but your saying their is aluminum oxide in the pad and the (spin cleaner thing lol) or cleaning it with the pad gets it in the pad? And even if it’s used on a dirt bike engine? Even a hone can do this? Sorry might be dumb questions it’s a kind of a lot too
Aluminum oxide is in both the pads and discs. I don't recommend either for cleaning any surface that does or could come in contact with anything in the lubrication system even in a dirt bike. No a hone will not do this, I was specifically talking about cleaning cylinders after they have been bored and honed.
I'd love to know why you think an AlOx honing stone isn't going to introduce the same AlOx particles. The reality is that it does. The other reality is that none of these abrasive cleaning methods should be used without a complete post cleaning. THAT is the reason these remnants were found in soft bearing material as they were used on a partially assembled engine. You can't properly clean an abrasive out unless the engine is apart. So the real lesson is stop using any of these abrasives unless the engine is completely apart and your going to clean it afterwards.
SME 2002 I would of imagined not many after cleaning, so what you are saying is cleaning the area with a lint free cloth won't pick these particles up? 😥

The bearings are made of aluminum, bronze, and lead. You can scratch lead with paper. You are lost

Glad I watched this I was just about to clean my dirt bike cylinder with scotch bright
so what do you use instead?
Metal scraper
Does this apply to Nikasil coated cylinder bores as well? (sorry if you said this in the video...)
Would it be okay to clean external engine casing with scotch brite? Like cooling fins etc...
Any proof of damage or is it just theory?
Yes proof of damage watch video. General motors study
Is red scotch brite any better??

SME 2002 okay thanks for the info I almost used one of these before but changed my mind

What about using 0000 steel wool?
That would actually be worse then scothbrite. Think about how bad thousands of tiny metal particles floating around would be.

The odds of getting them all is very low. The real questions here are why chance it and what do you think you are accomplishing by using it?
SME 2002 To clean up a forged cylinder wall that doesn't need honing for example? What would you use then in this scenario?
