What (if possible) would be the closest grit sandpaper that a camshaft bearing would be. Me and my girl have a cam that may go in, but it has some minor surface rust. A scotch brite can't quite get it off, but I don't wanna risk roughing it up too much. I may have to take it to a machine shop, but money is a concern.... Any help? Thanks.

 

I wouldnt use that cam, id get a new one.

 

you will never get it 100% smooth with over the counter sanding methods. a machine shop would have to take care of it. at that point you will almost certainly require new cam bearings. a machine shop would more than likely have to install them too.
get another cam or dont do anything.

 

ok cool thanks.

 

I have a factory late 2000 cam with about 60k on it if you want it, just pay shipping.

 

Dont use sandpaper on a bearing journal!!!

You might be able to try a very fine steel wool, but if its not coming out then its a gamble. Maybe youll be fine, maybe youll develop problems. Pics might help.

 

heard this stuff called navy jelly works i got a hint of surface on my cylinder walls going to try it

 

actualy you can use sand paper......like 1400 and brake fluid is great.. trust me i worked in an engine shop for a LONG time......cam bearings arent anything critical like rod or main bearings... as long as its smooth any microscopic sratches or pits will just get filled with oil. truuust me.

 

BUUUT stock cams are a dime a dozen on here, and I PERSONALY would probably buy a stock used cam..... but each to there own.

 

what about cylinder walls? had the head off for 1 day and it rained a **** load.. got the lightest/slightest thing of surface rust never had it rain while a motors open it went nuts I had a bag taped over and everything.. today I sprayed WD40 wiped it down then put some mobile 1 on by hand in the cylinders there to stop anything... I heard naval jelly works on removing rust but dunno if its safe in there

 

Extra fine sand paper or steel wool should take light surface rust off just fine. Use brake fluid or wd40 as stated above and you should be OK.

 

PM sent.

How did you know I was going back to stock? LoL
We may go back to stock since I dunno the exact specs of the cam in the car (but I was told by the owner it was an LS6 hotcam ). Plus we would like to put more time into the suspension/drive train than have to mess with the valve train and tuning, at least for now.

 

no. i wouldnt use it on cylider walls... because you will be useing new rings (i pray) and the rings will need the cross hatch scratches of a honing process to seal them to the walls.
