Hello,

for a 2007 model, I understand the 2.3L engine has a potential problem with filter houses cracking, and the 2.0L engine does not.
Is this correct?

How can I make sure I don't have this problem? (I don't think I have 2.3L engine but I want to double check)
Does nayone have a picture of what the 2.0L filter is supposed to look like, and where is it located in the engine bay?

I thought the conversion was for the 2.3L, no?
I'm asking about the 2.0L, does it have a standard oil filter? (the type that comes with its own metal round housing)

Spin on filter conversion, lots of threads on this one.

lotsa threads DISCUSSING it, but there are only 2 links to the actual product, and one is down completely. There needs to be a writeup on installing this unit. Its fine to discuss it, and how to do the DIY oil changes, but there are some that might need a writeup and pics..


Here is the one I found that is still working:

http://siteground207.com/~protegeg/product_info.php?cPath=160_256&products_id=1210

I like the writeup at http://www.supercar-engineering.com/rubberducky/Mazda3/Maint/2.3L/OilC/index.html

for the pictures. In there you can see on this pic

the cartridge housing and see the bolt where you would remove it, and replace with the product up above. should be straightforward.

EDIT: this is the closest to actual instal writeup I've seen

The 2.0L has a standard spin-on filter. The 2.3L has a cartridge filter with an aluminum housing and a plastic cap that can be cracked by negligent removal or installation.

The part about "negligent removal or installation" is key here. I haven't heard of anyone here who's had their filter cap spontaneously fail for no reason...but I've heard several stories about people who have had their caps fail after having a quick-lube place perform an oil change. The design of the cap isn't defective; the failures of the caps are really due to carelessness/cluelessness. If Mazda didn't have faith in the design of the cap, they wouldn't have stuck with it for the DISI (which also has a more complex oil filter housing, as there's a factory oil cooler). If you have a 2.3, take your car to a trusted mechanic or dealer, or do oil changes yourself, and you will have nothing to worry about.
