I tore down a 96 5.8 for rebuild and was intending to reuse cam but the first four lobes are pitted just like a flat tappet will do. My question is is there anything I should look for to correct that would cause this or is it normal. This is my first roller cam project so I am roller ignorant. Appreciate any help

 

Can you snap a pic of the damage lobes?

 

pics are not a problem its posting them that are....I am very technically challenged but I will attempt it tomorrow. What is the best (easiest) hosting site to use

 

Right here on FTE.

It's easy and the images remain versus getting broken links when the hosting site decides to change, something they do frequently!

Sorry it took so long....it's only the first four lobes and the lifter rollers seem ok

 

Looks like maybe there was an oil contamination issue, and there was a lot of grit being crushed into the cam lobes.

I'd replace the cam and lifters honestly.

 

X2....

 

I am replacing them no questions asked....my question is why just the first four lobes....couldn't be something in oil as that would affect all the lobes....I thought maybe there was a oiling problem I needed to know about on the 351. Thanks

 

If there were some grit or something someone got into the engine, say during an oil change, it wouldn't necessarily go to every lobe.
