Someone asked me today. What's the longest oil filter for our engines. These are the ones that I know. Two of the short ones that I wouldn't use. Fram PH25, and WIX 51307are 3.5 inches long. WIX 51049 is 5 inches long. I'm sure that there are more brands that are 5 inches long. Bob Dunahugh
 
Bob,

The Wix 51307 should NOT be used in either a 455 or 403 as it has a bypass valve.

http://oilfilterdata.com/index.php?view=filter_info&model=51307

The oil filter adapter of the 455 and 403 has a bypass valve in it:

Nor should any other filter with a bypass valve; I learned that from presentations made by Dick Patterson.

The Fram PF25 does not have a bypass valve, however, before I used on I'd cut it open and see what the total area of the filter
element was.

Here's a link that shows a Wix 51049 filter element unfolded and stretched out;

Do, how about the Wix 51258? Been using that for a long time. IIRC it is the shorter version of the 51049.

Larry,

Agreed, the 51258 is a shorter version of the 51049; it is the same diameter so safe to assume that the length of the element is the
same, just not as "wide."

I tried the wix 51049 and it was too long and would not fix because it hit the starter.

That's very strange, Mike. I'm using it on my '76 Palm Beach 455, with no
problem. I didn't check for starter clearance but I do know that it isn't
touching anything.

Something seems strange. I also have a 1977 Kingsley with the 455 and use the Wix 51049 and it has plenty of clearance with the starter.
Are you using a non-stock starter?

The starter is a rebuild. It looks like it would fit ok if I removed the starter for the filter. Needs maybe 1/4" or so more clearance. I don't
remember exactly where the interference was but did not fit.

There are different diameters too.....even through the seal size is the same.

I have been using a Purolator pureone PL25288 oil filter it is small 2.75" dia. X 4" long no bypass valve and filters to less than 5 microns.
Just what I use fits and works.

I looked up that filter and the site I went to said that is a 25 micron not a 5 micron filter. I thought 5 micron was very small for oil.

Mike,

I've never heard of an oil filter that filters down to 5 microns so I Googled the Purolator and here's what came up:

Note: Efficiency: 99.9% @ 20?

The old flat VW engines had nothing but a window screen in the pickup. A little finer that the one in ours, and our engine all by-pass the filter at
some time, so I refuse to worry about the filter quality past its basic crud catching....
If you remember, I had a timing chain that was bad because the little hole go plugged with a piece of carbon at some point. I will put a strainer in
there, but I will stay with a good name oil filter only because I had a bad one break up on me (when you see filter paper in the outlet, that is a bad
filter).

I've had several Vw air cooled and was always amazed at how much crud was on the clean out plate when I did an oil change.
The last Vw flat 4 I had was water cooled in a vanagon and that had an oil filter.
I had a filter in my Vw Touareg come apart. It has a replaceable element in the housing. The plastic ends came unglued from the media so no filtration
for some time.
