I have not yet removed the cam but here is a pick of one of the rollers



Looking at the cam through the lifter bores, it looks about the same. I will be removing it sometime this week and will post some picks of it.

I can't be upset, I have about 50k miles on this cam and a touch over 80k on the stock lifters. I am just glad I decided to tear the car down when I did. I was going to install some aftermarket heads and leave the TR224 cam in for a little longer. But I will be adding a new FMS cam along with some LS7 lifters soon enough.

 

cant see the pic?

 

did you see anything in your recent oil changes? one would think something wearing that badly would be evident.

 

i wouldn't chalk it up to normal wear and tear...

i had about 78k on stock lifters and 56k on a 224 cam and when i pulled the heads they looked perfect...

 

No excessive debre on the tip of the drain plug, but that is a subjective exam.

I am thinking that I was getting some consistant valve float that may have caused some of this.

 

That would do it.

 

dayum, never seen a lifter like that. How do the others look? Could be a faulty valve spring.

 

they all look about the same except for 1 or 2 look decent but not great.

 

well, just make sure the cam lobe is okay so you don't mess up a new lifter when you replace it
