Roy I did a Google search on the part# 110 180 03 55 you show on pg 15 post#225. and MB of South Atalanta come up and lists the part as NLA.
STRAINER. SUCTION BASKET. Mercedes 600 SEL V12 # 1101800355
I think it is also listed in the Unobtaniul parts thread also.
So what would you recommend for a replacement? I suppose there are still a few floating around with some of the parts suppliers, or on a shelf in someone`s garage.
I pick up looking a the MB site above, this part was used on a lot of MB engines over the years.
Might have to start dropping oil pans at PNP.
