I bought a used engine to swap into my firebird and before I got the heads on the cylinder walls got a chance to surface rust. What should I use to clean this up? Brad

 

wipe them with wd40

 

Really, thats it? I dont need to get the rust off before I put the heads back on?

 

Scrub the rust off with a coarse rag and oil.

 

I tried that and couldnt get it off. What happens if I leave it on there? I am gonna go and try to scrub harder this time and see what happens.

 

see if you can post a pic of it so we can tell you how bad it is (or isn't)

 

I have a digicam but recently purchased a new PC and dont have the upload software It is only rust from sitting for 2 days when it rained. Was very humid afterwards and no it didnt get rained on, lol.

 

It's probably inconsequential surface rust - unprotected iron will do that almost immediately in moist air. You have peaks and valleys in the cylinder hone pattern, and you probably can't scrub the rust out of the scratches without an abrasive - you should probably just clean them up with paper towles or lint free rags and wd or something similar and call it a day. I suppose you could use a scrub brush if you wanted. I had that happen to me a couple times in the past and nothing came of it.

 

Thanks for the help man. I decided to put my timing chain cover on instead of mess with the cylinders but going back out in a sec to try the rough rag and wd 40. Brad
