Someone a couple of months ago suggested "CD-2" lifter rebuild in a can (I
don't remember exactly which CD-2 product it was, but there's only one that
claims to "quiet noisy lifters".)  This , of course engendered a bit of
discussion about oil additives in general.  Having suffered from Vanagon noisy
lifter syndrome for years, on a motor that will turn 180k miles tomorrow, I
felt that I had v. little to lose.  I gave it a try.  It "quiets noisy lifters."

Don't flame me.  It worked for the suggester, it worked for me.  If you don't
think it's wise to put additives into your crankcase, DON'T!
