Zinc

As I said in another post 540RAT was exposed on SPEEDTALK and kicked off the site for bogus testing procedures etc.

Be careful what you read.

Spot on, including the Isky roller lifter fiasco. 540Rats a dick.
I just don't see how difficult this is for some people.. Just buy a good oil with zinc in it.. simple..
If you can't manage to do a simple task like that, then you deserve every cam failure you ever get..
