Hi Bob,
Yes - Of course I meant SM. Please excuse fat fingers, dyslexic?
I got VV851 from my local auto parts store. He said they didn't have
any such until I gave him the part number. It's frightfully expensive
though. I think for my use, a pint of EOS #1052367 combined with my
traditional VR1 20-50 will do the job at less cost.
Who knows how much longer GM will keep selling EOS, though. So far,
they have just changed the label & recommendations.
I'm especially interested in the subject since I AM breaking in a new
flat tappet cam & lifters.
Regards,
Dave Russell
