My 350x keeps leaking oil out of the oil filter cover...

[SWIGIN]

My X leaked after a oil change as well. The area that the oil cooler hose sits in must be spotless. I used a q tip and got down in those tiny cracks. That is were my problem was and made it seem like it was leaking from the large cover o ring. If that does not work, Dirtcrasher's input would seem to be my next step as well. Good luck

Well it's just common sence that you need to keep those areas clean. But regardless on how clean you have it you do need all the O rings...lol


I'll try to go get a pic of the little O ring and where it goes and post it here since this has come upmore then once.

OK, here is the little O ring sitting in it's groove. This is the one I have seen a bunch of guys loose then say they can't stop a oil leak. There is a total of 3 O rings for the cover, 1 for the top oil line, 1 large one that slides into the filter area, And this little fellow.



Even if you have this little O ring it might be flattened out from being old and not sealing well. my buddy had a chromed 350x oil filter cover that he gave me for free because he said he could not get it to stop leaking. After I cleaned all the silicon sealer out of it and used ALL new O rings it never weeped a drop.....he was pissed....lol

I just got the same problem on my 250sx after changing the oil

I wish I didnt read this thread... I feel like I am going to be jinxed after this... LOL
Anyway James, look at it this way, you could have a stripped drain plug like me. I love my 350x, but damnit, everything seems to go the "hard way" on this thing.
Let me put it like this... When I changed the carrier, it took a 5" grinder, a large pipe wrench, and a new anti fade nut assambly to get it all done.

wow... I've looked like 5 times at that cover and never once realized that there was an o ring that went there. I will go order one (maybe 5 just in case) and then swap out the cover. I guarantee that there is no o ring there because i took a wire brush (toothbrush sized) and scrubbed both surfaces. I feel like el stupido now...

Thanks guys!!!

FWIW, I'd never use any size wire brush on a sealing surface. next time just use a rag and some super clean, or a real tooth brush.
