Try a telescoping magnet maybe..

Aluminum magnet

What is harder? The ALUMINUM that you shaved off the intake or the IRON that your rings and cylinder walls are composed of?

News flash. Soft things can not scratch hard things.

Hmmmm...really?

I've been building race engines in cars and motorcycles for many years and you'll be amazed what kind of damage an ALUMINUM piston can do to a STEEL or even NICKEL PLATED cylinder sleeve. It's not always a case of how hard the metal is.

I think he was trying to say that a less hard material can still scratch a more hard material. A sharp piece of AL with scratch iron, the AL will get way more worn down, but in the case of an engine even a little scratch can cause problems when it is repeated 1000 times, on the cylinder wall.

yes, thats what i was saying. i guess the internet doesnt convey witty comments very well

Usually the damage is caused not by the aluminum pistons but by the iron rings from having ring end gap too small or getting cracked from detonation.

I, too have seen galled up bores from aluminum pistons, but once they are honed, the aluminum goes away.

Back OT. Soft materials do not scratch hard materials. Saying things like you can cut steel with aluminum is just retarded.

then tell me: how DO you cut diamond?

For the love of God, pulling the intake takes 45 mintes. Pull if off clean it out and be done with it.

And OW GTI, tell me how a brass iron brush powered by a drill (which travels at less speed then a piston) can scuff an iron block?

you should have took you time and done it right

92tealTSI · Sep 20, 2005

I meant brass wire brush

OWGTI · Sep 20, 2005

Is it brass wires or brass coated steel wires? Shenanigoats.

I cant imagine that it would be a solid brass brush, that would be expensive and brass is soft.

92 Teal TSi Please explain to ME why you use a brass punch when you dont want to gouge whatever you are hitting.

you know take off the manifold and damn this got off topic I don’t know much about metal but I think it depends on how hard it is tempered (im prob talking out of my ass ) So you cut a diamond with a diamond solid brass brush I think not. steal brush with brass coating yes and aluminum i guess could scratch steal if it was hard enough.
