Help ,oil Filter leaking??
Ive only owned the WRX 2 weeks, last week I changed the oil and filter. The filter that was on there was a Ryco Z495,I couldn't get to a Subaru outlet to buy a genuine filter so I did some research and many were saying next best option is the [B]Ryco Z436 [/B]so I fitted that.
The Z495 Filter that was on there did not leak a drop but after fitting the smaller Z495 one it started leaking out of the O Ring on the Filter??. Ive cleaned it off twice and double checked= definitely out the Filter O Ring. I keep hearing guys saying that sometimes folk leave the old Filter O ring in the Housing by mistake then it leaks but on mine, the filter housing [B]HAS NO O- RING RECESS!??.[/B] It mates up to a flat surface on the Filter housing?. |
did you apply a little bit of clean oil to the o-ring on the filter before fitting?

Yes I allways do, Ive never had an Oil Filter leak on any car Ive ever owned and I'm 40! so had a few cars now. All I can think of is maybe I did it up a little too tight,so I backed it off a tiny bit but will have to see what happens tomorrow, though the leak was reasonably bad.... |
An oil filter should have a rubber I ring recess on it. Sometimes to I ring gets stuck to the oil cooler.it really shouldn't be anything else. If you've done everything right, unless the sump plug washer is leaking ?

I keep hearing about the O Ring left behind in the Cooler/ Housing but for some reason mine 100% HAS NO RECESS IN IT?? the filter's O - ring mates up to a Flat Surface yet seems everyone elses has a Recess in it??? from what I'm reading online, I checked the Sump Plug area and its fine. Indeed the filter has the Recess for the O Ring but not the Cooler,I don't see how anyone could not see an O ring stuck to the Cooler, not on mine anyways.. |
Your oil cooler it's self has an I ring further up. They might be talking about that.
|
did you clean down the oil cooler before you put the new filter on?
in my experience non gen filters do tend to leak alot more of the genuine ones |
Guys I cleaned all the surface of it prior to fitting, the higher up Oil Cooler ring on mine is fine, ive checked a few times after cleaning the area.
Sounds like I need to get a genuine filter then ASAP |
Some of the smaller aftermarket filters bottom out on the thread before the O ring fully contacts the cooler.
I would be checking that if the leak is still bad. |
What year rexy you got? Im pretty sure the Pre-MY00 are suppose to be Z495. Z436 are for the later models??
Also the oil filter housing surface is suppose to be flat, no recess, only the filter has a recess for the O Ring. What they mean is when you remove your old filter the O ring from the old filter gets left behind on the oil filter housing therefore placing two O ring filters (usually only happens on model of vehicles when you can see the housing). |
