get at the least 3 oil changes in on it(1,000 miles). I really think that it's limited to the dual spring setup and not the single springsOriginally Posted by GMC93
Nah not yet but the truck only had a couple hundred miles on it since the cam swap. I was hoping i had caught it before anything happened. What do you think?

Ive pulked two comp cams that looked just like that. One even had a nice 20 thousandths groove a lifter roller wide cut into one of the lobes. When I decide to buy another cam it wont be from comp nor will I be using their springs. Both incedences I had were with prc dual golds.

They buy the least expensive cam blank's and sell them at the highest price on the market. This pays for all the marketing that helps keep them at the top of the list.

Well my motor is back together with a comp camn 233/239 and dual PRC springs. What are the signs that the cam is flaking? Something that I will notice in an oil change? Does it cause major problems or is it something you will only notice if you pull the cam?

To the OP... on the cam pictured, are the 'flakes' on the trailing ramp of the cam lobe? If so, the valve train setup could be to blame due to instability and 'pole vaulting' the lifter off the top of the lobe. When it crashes down with the high open pressure of aftermarket springs, it beats up the lifter roller and cam lobe.
All of the damages that I've seen on the lobes are always on the entry side, exiting has been ok.Originally Posted by BigKID
The lack of ZDDP in modern oils due to emissions and the effects zinc has on catalytic converters has been a hot topic for a while now. There could be some truth to the debate with higher spring pressures and aggressive lobes even on roller cams. Valve train setup probably has more to to with the lifter and cam lobe failures on hydraulic rollers than anything.

There was one that had been ran for much longer, and it had flaked all the way around a lobe. This was blamed on a lifter issue and not a cam issue. Now I see that it's complete BS
