Rust on top of cylinder wall?

[samuraichamploo]

Is that a big deal?
theres a very very small amount of rust on the top 1/8th of a inch of the cylinder wall.
I dont even thnk the piston comes up that high but figured id ask.

i dont think that is rust.............i think you are seeing thick brown carbon deposits i had them on my cylinder walls.(where the pistons didnt touch)

get a ridge reamer and cut it off so the top ring doesn't catch on it and break, if you want. You can just put it back together, that's a normal feature of piston engines

 

[samuraichamploo]

nono, its inside the cylinder.
Its rust, water got in it, but not enough, only so that it got down 1/8 of a inch.

its definately ***ed it up dude, just ship it to me i got good use for it.

 

[samuraichamploo]

are you serious???
its only 1/8th of a inch from the rim!
Im gonna buff it out and hope for the best.
the ****ing piston ring wont even hit it.

 

[Jay5_o]

Im only joking. i dont think it will matter. was the engine sitting around awhile not being run or something ?

 

[samuraichamploo]

its had rust on it for a max of 2 weeks
its now covered in plastic and soaking in oil to prevent further rust.

Take a little fine emery cloth or a fine scotch brite pad, spray a little wd40 on it to catch the debris and lightly clean it up. If it comes right off - no problems. If it's deep enough so the cylinder wall is pitted, and it's below the ring line - that could pose problems.

ya, dont worry, its nothing. just clean it off good and it will be the very best

 

[samuraichamploo]

Should I worry about the dirt and debris that falls onto the cylinders?
i cant vaccum it because its sticky with the oil that was in there.

(with a rag) wipe out the debris you can, bring the piston to top and wipe it off, then drop the piston again and some more debris may be left behind to wipe out.
