It's because the pumps are all aluminum and they wear very fast when cold. Once they reach operating temperature, they wear very slow.
Also, the pump has one piston in the center & a distribution plate they aligns with each output port in turn. This means that the one little piston is working 8X harder than the inline pumps used on Mercedes diesels.

Just curious, I've been thinking it'd be cool to put a 350 diesel into an S truck but that would probably see quite a few highway miles. Is it because of lower speed running or stopping and starting? -Curt Date: Fri, 14 Mar 2008 09:13:03 -0500 From: "Tom Hargrave" <[EMAIL PROTECTED]> Subject: Re: [MBZ] Olds diesels was Re: Craigs list finds To: "'Mercedes Discussion List'" <mercedes@okiebenz.com> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="windows-1250" By 81, the Olds diesel was a good engine. And I understand why your friend kept 2 pumps around. The engine uses a rotary pump. The pump will go 100,000's of miles on the highway but 50,000 city miles will wear out. I owned a 81 Pontiac Bonneville with the Olds diesel. It was one of the best cars I've owned to date. I killed the engine at 150,000 miles.
