How long do camshafts usually last whether they re beaten on or lightly used?

I want to buy some TODA camshafts that have around 8-10k miles on them. How can I identify wear & tear or is the investment worth it to buy them new?

Thanks

They always last exactly Three years, 12 Days, and 37 seconds.

Like everyone will tell you it depends on way too many variables to say.

If they're pitted, or grooved or rusted, or disgustingly dirty I might stay away. Although once again it's an edjucated guess.

 

Good question, but I think it would be best to send the cams to Toda (if you have Toda cams) so they could recheck/mic the cam profile and see how worn down they are.

One major thing that can contribute to cam lob wear is valve spring binding. If you don't run the right springs with the right cams, you'll eventually wear flat spots into the cam lobes. This is rather rare though..

You could also visually inspect the cam lobes for flat spots and wear, but normally camshafts last a loooooong time and there's always variables..

 

I bet you'd get more help if your thread title at least hinted at your actual question.

 

Thanks guys! I appreciate all the help. Im sure everyone understands how "iffy" it can be buying good expensive gear and not knowing.

Anyone can add to the thread, please, but I'll stay away from rude comments...thanks again!

Visually inspect them. Go on google or on Toda's website and look at pics of how a new cam looks like and compare. if it looks exactly alike (which it should, unless they're beat to ****) then you are fine. 10K is nothing.

 

One thing I would worry about is the scarring and pitting stated above, but before I would even consider picking them up, check to make sure they are still straight. Look for signs of taper on the bearing surfaces.
