I noticed that I have a brown ring at the top of my cylinder wall (A6), most likely thats carbon but then I noticed some brown like spoting just a little lower. Its not alot and I only find it in the #3 cylinder, the spotting that is, all the other cylinders have that ring on top. Is this going to be a problem, or is it no big deal, I'd hate having to buy another block

Here's the pics, tell me what you think.

hone it

Any idea how much that would cost?
and will it affect the bore size?

i'm pretty sure honing does not effect bore size. and you can probably do it yourself w/ a honing ball.. again wait for second opinion though.

honing is easy, just borrow on honing tool from someone and use a drill. it doesnt affect the bore size, it just makes the cylinder wall rougher so that the rings will wear perfectly into the cylinder

And make sure u lube the cylinder walls good. It kinda looks like rust to me...was your head gasket leaking?

It might have been leaking from the gasket, I know I bought the block smoking, not alot but it did smoke a little bit. So botton line, a good honing is all I need right?

were do I pick up one of those honing tools you guys speek of?

I'm not too sure where to get a ball hone, but i know u can get the bar style hones from napa. Also try to get some hone oil while you're there.

Is a deglazing hone the same thing?

Slo_crx1

Yup, pretty much...just try to find one with the highest possible grit...you're looking to scuff the cylinders, not eat through them.
Also a few tips for honing: Use plenty of lube, always keep the hone in motion, and try to keep your crosshatch pattern at a 60 degree angle.
I hope you're changing your piston rings also, right?
