Also, for the OP and myself, is it really true that running synthetic oil can quiet the lifters or is that MB folklore? Thanks.

just wondering if he had low oil pressure at idle, since he pulled the pistons, but did not mention replacing the bearings.
I can see if the lifters were sticking from varnish or thick oil, changing to synthetic could free them up.
I use nothing but synthetic on my 603 powered cars...
