Purolator oil filter
 

2 weeks ago I changed the oil filter in my 83 300 D using a Purolator Premium plus L43056 from Advance auto parts. I know, I know it's not oem but I couldn't wait. Anyway, there are 3 copper washers that came with the Purolator that I did not install because none came out with the old filter. I only installed the large rubber o-ring gasket.

It's bugging me that there are extra parts left over. Did I screw up or should they go somewhere?

One is probably for the oil pan drain plug.

The two same-sized ones go on the oil filter housing cover. The bigger one is drain plug.

I was told that the same filter is used for many applications and that those washers are for the 'other' models.
Wierd thing is when I was messing with 126 gassers, the same question was asked and the 'other' models were OMs. :confused:

The two large washers are not utilized on the 617.

BTW, the Purolator is a POS. I've used it for several years until I cut it open. It's so bad that I threw out the remaining two brand new filters. :eek:

You mean you through away 2 perfectly good roach motels? :eek:

Well I'll be... I was always curious about those

A lot of the Ford guys get filters at www.fleetfilter.com. They're Wix filters though.

That Purolator would be a 51385 for $6.39.

Wix for MB
 

I almost installed a Wix oil filter today that came with my car purchase, until the O-ring that came with it didn't fit inside of my oil housing cover :pukeface: plus the Wix filter also was designed slightly different than all the other OEM brands (it didn't have that 3/4 metal part on the upper half of the filter).

Long story short, I installed the Hengst filter and the O-ring that fit and everything is great :beer:

I like the German OEM for my MB :uzi:
