My question really is cant used Cams hurt ur motor or miss up ur motor if somthing is wrong with them or just being used? What r the changes of them working and have nothing wrong...

im not too familar with cams really at all... i just wanted some peoples oppion that know much more then me

 

yeah it can be bad, if the lobes are all worn out and the cam is in bad condition, BUT unless you know the person buying from i would not recomend getting used cams.

 

People upgrade all the time.. And often the buyer won't know the seller. If it's a name brand cam.. It would have to take years of abuse before the lobes wear down. It's generally safe.. I would say it's best to ask for a picture and judge for yourself. You can usually tell when the lobe has worn out enough that it's not usable. Feel free to ask for a measurement to satisfy any fears.

 

Your better off buying new cams.

Otherwise I would inspect the ones you are purchasing thoroughly or request for detailed pics

 

You have an Evo 8 .. so NON Mivec.. The only time I have heard of cams breaking were on the Mivec INTAKE cam on the evo IX (9).. It is fine to buy them used as long as the lobes aren't terribly worn out. so like every one else said, just simply ask for upclose pictures to verify the condition.. Most people, like myself, usually sell cams because they want to try something different or upgrade to something more aggressive for more power.. but keep in mind.. when you get something more aggressive, you tend to lose spool of the turbo.. From my experience, Kelford 272s, GSC S2's, Cosworth M2's, FP 4R's, etc are all good well rounded cams .. Try to find a set of one of those.. Good luck!

 

There are just some things I'd rather spend the extra money on and get new. Cams are one of them.

 

FWIW, I purchased HKS 264s off of a dude and they were perfectly fine.

 

I've bought used cams a couple times, all perfect for thousands of miles.

 

Yep so did I--HKS. If it was any other design of cam and rocker I would say no way for a used cam---these parts wear in together so thats the issue. With the roller tips riding on the cam--unless the cam is showing wear there should be no issues at all. Need to be sure all your rockers are in good shape as well and not showing wear on your existing cam. Other then that--drop them in and lube your lobes before start up.

 

It amazes me how skeptical people are to buy to a set of used cams for an avergae cost of 350, but we spend thousand of dollars for a used Evo with everthing used....majority of what is not visible to the eyes, like the cams!!!

 

Always buy new motor parts.

 

I completely disagree. There is nothing wrong with a used set of cams as long as all the lobes are in good shape. This should be by far the majority of them.

 

i wouldnt buy used internals but thats my .02

 

opinions are gonna come out of the woodworks on this one. It's all about personal preference. I don't believe any answer given will have concrete evidence one way or the other. You are gonna take a bigger chance of faulty parts when buying used, that's bottom line up front. I personally don't like the idea of saving money on parts that have moving metal to metal characteristics. Next question would be, can you purchase used pistons, rods and crank. Can you save money, yes... but why. Good luck with your purchase.

 

I would buy used cams for sure. No big deal to me. Just look them over and make sure there is not excessive wear on the lobes.
