Oil Sample...Lead

[dumbo]

Well I got my oil sample results back. Pretty well I was pleased except for my Lead was 9ppm. My question is can it only be rod/main bearings, or can it be my turbo? I also changed one of my cams few hundred k's before the sample but there isn't any lead up there correct? Only steel and aluinuim. Any comments/advice please, I'm seeing rod knock in the future.

Also my engine is a 7M-GE with turbo, running Castrol GTX 10w30 on the sample, switched to German Castrol.

Damn a few hundred k?!! You must drive a LOT! Sorry, had to be a smartass:naughty:

what do your aluminum and copper look like?

9 ppm isn't a hell of a lot, and could be associated with test error.
