So I am trying to stay away from boring out if any all possible. I got this block free and it has rust in the cylinders, I noticed what is looks like some light pitting. I can barely feel them with my nail. Is it possible that a hone will get them out? I dont want to waste my time if it wont.

The rust itself comes off very easy

If its very little pitting and just surface rust you should have no problem getting it off, but there might be wear in the cylinder from when it was running. hard to know without trying

Well the guy I got it from said there was not a lot of miles, it just ran with low oil and killed a rod bearing. and the top of the cylinder has no kind of lip from wear. So i have hopes it has very minimal wear. Im just wondering if anyone here has done it before and they it came out good.

I would be worried more about the bore roundness, wear, damage, ect.

The rust should not be an issue after hone.
Even if slight minimal pitting is still present as they will just end up retaining oil, just as long as damage doesnt run the length of the cylinder wall, and your cylinders are round and in spec after machining/hone,
you should not encounter oil control issues.

Scotchbrite or 3M rust removing pads will help you clean things up a little better to get a better view of what your dealing with.

Then you can present it to your machinist and get the best opinion availible.

Thank you for the input

I had a block that had slight rust in it. I just took wd40 and sprayed it on the cylinder walls and haven't had a problem with it. But it wasn't near as bad as your pic so I would try a hone and go from there.

spray it down first, clean well.
what ever is left the hone should get.
make sure you get the walls gauged for roundness before proceeding.
