    Before we condemn the cam.. what does the roller of the suspect lifter look like? If it's looking good, then the cam is likely not an issue. No metal in the oil pan is also a good sign that the cam is fine.

    Is compression on that cylinder still an issue?
    I drink..so consider that when reading my posts.

    I meant to post a picture of the lifter roller. Does this look like proper wear?

    Joe.. Dave is worried you plan to yank the cam. Looks like it's probably fine and isn't causing your issue.
