Here is the list of filters that I posted in the oil filter forum.
2003 Sienna / 1996 3.8L Windstar
Bosch 72161 / 72143
Bosch Premium 3330 / 3422
WIX 51348 / 51516
ACDelco PF53 / PFL400A
Fram X2 XG3614 / XG3600
Mobil 1 M1-102 / M1-209
K&N HP-1002 / HP-2009
Purolator PL10241 or L10241 / PL20195 or L20195
WIX and Purolator list specifications on their websites.
I noticed that Purolator lists a slightly higher bypass valve pressure opening value than the WIX, in both the Windstar and Sienna versions.
I have the "filter cap" type filter wrench that you use on a 3/8" ratchet drive....works VERY nicely.
I bought it some years ago for another vehicle (it has fit the past 3 vehicles I have owned!)
I bought the expensive "special tool" funnel that has the 1/4 turn to go in the oil cap mounting.....
It is AST Tool # OFTOY1001 2009 list price $59.23
If you have the threaded (not 1/4 turn) oil cap the AST # OFTOY1038 2009 list price $27.50
There is a TSB that warns about bending the baffel under the fill cap when adding oil.
I put 2 bottles of AutoRX in on Sunday, using the WIX filter.
I had very slight stuff like in the picture above on top of the oil baffel at the oil fill point.
However there is NO varnish or any other deposit on the dipstick.
Vehicle had 5000 mile Oil and filter changes.
I just got this vehicle, and have been surfing the web, reading up on what I can.
On the subject of PCV valves......I see several styles listed for my 2003 Sienna.......I orded the metal one that threads into the valve cover.
There are others listed that mount into a grommet and have a 90 degree elbow at the top.
One website listed those for early year production.
I am thinking, for the 1MZ-FE motor, more flow (within reason) is better.
