    Well, because of lack of time and my engine just sitting with nothing in it, the cylinder walls got a little bit of rust of them. I plan to put the new pistons in maybe this weekend. I have been reading around on this and have heard of everything from just putting the pistons back in and running the engine, to steel wool and oil. What do you guys recommend to get rid of a little surface rust?

    a slight hone will solve any problems, as long as its only surface rust.

    to prevent this you shoulda just spray liberally with wd40 or engine assembly grease ('white')

    Ya, seems to be just surface rust. So hone it, and clean it then.

    And don't even think about putting steel wool anywhere near your engine. :thumbsup:

    Yeah steel wool will kill your cross hatch, don't plan on having you pistons seat if you do the wool.

    Ah, steel wool would even be bad if you used it before the hone? Or are you just worried about shavings getting caught in the motor?

    "shavings".. its amazing what a little piece of steel wool would do if cought in a main bearing. You couldn't possibly use it and expect to not drop a few threads down into the block..

    it'a amazing what a "crumb" of rust can do to a bearing too.

    completely flush out the block before re-building... use an air tool to blow it out or somethin

    dip the block in doo doo butter, if you dont , its shot im sorry


    but seriously, strip the block bare. hone it, clean it, then assemble.

    if its been sitting for awhile, it may be pitted, if it is, youll need to bore it.
