I35 Oil Filter Adapter Gasket & Oil Pan Gasket

[Logank]

Hey everyone,

New to this site, found it while searching for some info on a few problems I'm having with my 2004 i35. The posts I found here were the most informative so I'm hoping someone can clarify a few things for me.

I took my car into get an oil change and the mechanic told me that I need to replace my Oil Filter Adapter Gasket, as well as my Oil Pan Gasket- at a labor cost of $400 total (the parts were around $20-30 total).

I replaced my oil myself this last time, noticed what he was talking about regarding the oil pan gasket. As far as I can see, it's just a sealant of some sort, maybe silicone, gasket, right? Replacing that seems fairly straight forward, remove the oil pan, clean off any gunk, apply the gasket with sealant, let it sit, re-apply the oil pan and let it sit. Anything I'm missing here?

When it comes to the Oil Filter Adapter Gasket, I'm not sure if that's referring to the oil cooler gasket, or something else? I read a post on here where someone said,

"I had the same problem with my 2003 I35 oil cooler, but was able to fix it in 5 minutes. The problem is not the gasket (quality rubber gasket, can't imagine it ever going bad). It's the actual oil filter stud tube (what the filter screws onto). It loosens up over time from oil filter changes.

All you have to do is remove the oil filter and tighten the the stud tube, just that simple. I'm sure this is the case for all Nissans and Infinitis that use this oil cooler/filter combo. This should save an unnecessary pricey trip to the dealer."

Can anyone give me an idea which problem I'm having?

Thanks so much in advance for any help!

I would not take is offer on the oil pan gasket replacement
A nine year old car could have oil leaks from several places
I think any mechanic should know this
I would get some auto ramps, rags, and degreaser and clean the area well
and then re-assess the problem. It might be your valve cover gaskets.

Never heard of the tube problem before
Your best bet is to check the schematics on the Floor Shop Manual

The schematic needed is on page 31

The parts involved appear to be the;
Oil filter
Oil Cooler Connection (that looks like the stud tube item you are discussing)
Oil Cooler
A gasket behind the oil cooler
Relief valve

There is also an oil pressure switch nearby. These things like to leak too.

any of these could be leaking. It sounds like you know more than the mechanic
Looks like the stud tube needs between 33-39 ft pounds of torque (if you can
get a wrench on it)

i would clean it all up first before trying anything

my comments above stand as the schematics for that area are the same

I had to replace the gasket on the oil pan. Just use RTV sealant and that did the trick. I let it sit for a couple hours before putting oil back into the car. Have to be careful with removing the old gasket as you do not want to gouge the block.

Thanks for the help guys, really appreciate it.

I ended up removing the oil filter adapter/cooler and replacing the Orange o-ring in the back. Pretty much did he trick.

Still have a TINY leak in the oil pan gasket, going to tackle that soon. But it's not enough of a leak for me to worry at the moment.
