VTEC Lobe Wear (Pic)

I did my lash and noticed one of my intake VTEC lobes has more wear on it than others. I cant catch my finger nail on the worn area but I used a feeler gauge and I could feel that it was rougher where the wear is. Is this normal or should I be concerned?

Thanks

take the cam out and inspect the LMA (lost motion assembly) for damage. The LMA should move up and down smoothly with constant pressure. If it sticks, then it needs to be replaced.

what year is your motor?

Here is the only other pic I took at the time, unfortunately it doesn't show the same same lobe face as the first pic.

Blake, from what you can tell from the pic. do you think its urgent that I take out the cam and inspect the LMA? I don't have a second car, so its hard to arrange time to do something like that.

you dont really have to remove the cam, just press down on the vtec rocker to see if there is any binding/sticking. However, if are catching the beginning of the rocker beginning to galley, then it is pretty important to figure out what is going on between the two metals.

what was the valve lash on that cylinder?

Thanks for the replys. The valve lash was around .007 I believe. I plan on doing the timing belt and waterpump soon, I'll inspect it closely when I have it apart.
