During engine assembly, Connecting rod cleanup etc.

Hello guys hope you can help me with info on these few questions. I currently have my rotating assembly at the machine shop to get balanced etc. I got a set of Scat i beam capscrew rods for a 350 chevy. I know they come in special bags tha are sealed so they don't rust or anything. Now after the machine shop gets throuh with them I know they will have some rust on them on the beams because of them handling them. I know the rodbolts will have a small amount of spec's of rust on the bottom of them but is that a bad thing when they get like that. i know you have to clean everything and wipe it down such as block crank etc. What can I do to get the rust off of the rods and rod bolts so they will be clean when I put the engine together? I read from eagle that if you get any rust on the rods or bolts they are no good to use and must be replaced. For you guys out there over the years when you have put motors together what all do you do to clean up the rods of any rust or anything and are they still safe to use? Thanks for help.

Every time I ever got anything back from my machinist it has no rust on it period. Any shop that hands you over rusty material isn`t that good and wouldn`t get my business. However, I think your overly concerned. A spot of rust can be cleaned by WD40. If it`s basic surface rust as in this case, The WD40 will wipe it right out. Clean you engine good, scrub the bores to be sure there is no hone grit, rinse it, hose it with compressed air, and coat the machined surfaces with WD40 to prevent any rust and you`ll be just fine.

scrub the suspected area with a green scotchbrite pad and wd40. keeping them wet with oil will eleminate the rust from forming...

Unless the shop is a total hack job the rods will come to you clean with out any rust.

I think you might be over thinking this deal a bit. I have had rods in my shop hanging on pistons for 3 or 4 weeks waiting on other parts and they never get any rust on them, not even surface rust. There are some guys that have problems with there hands making things rust when they touch them. Even that will come off with just a bit of hand work and some scotchbrite, like was mentioned above.

Thanks for the input appreciated. I just had minor surface rust on my last set of connecting rods. They are from Scat and after I handled one and put it back in the bag it started to have a little rust on them just surface though. I have no clue what was used to clean them up. I was told to use pb blaster to spray my engine block down once I get it back from the shop. They are also going to do a final clean for assembly so i will just have to do a final scrub down with soap and water then blow it out with a air blower from my compressor. I will use a scotch brite pad to clean up the rods really wellso I wont have to worry about them. Thanks guys
