My '81 300D had the U-shaped vent pipe. Tom Potter
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Merle Sent: Tuesday, February 20, 2007 1:41 AM To: Mercedes Discussion List Subject: [MBZ] Water pump vent pipe Discovered that my 79 300D ( non turbo ) does not have the vent pipe from water pump housing to head as it should have according to the parts list. Could this explain erratic temperature fluctuations as I suspect that air pockets are forming in the engine due to cavitaion or whatever. Later Om617 ( +- 1983 's ) however did not require this vent pipe even thogh pump and housing remained the same - so I'm a bit puzzeled as to weahter one actually does need this vent. Anyone have any info on this matter?
