I just purchased a 4 year old RX-8 about 5 months ago. Went to go get a oil change after 8,000 clicks and the mechanic noticed that my air filter was full of oil. Later on that day I took it out and half of the filter was pretty much fool of oil. I went to the dealership so they could take a look at it and they told me it was normal. The guy was like... "i have a RX-8 too and i have that same problem, all you have to do is get a new filter." I don't know about you guys but air filters are exactly that, not oil filters. I thought it could have been a loose apex seal that lets oil into the mix while the engine is running which means I would need a re-build. I thought that maybe they didn't want to re-build it because it was under extended warranty, i don't know i've been warned about dealers and mechanics. The guy at the dealership said its a high rmp engine (obviously), and it spits out oil when you rev it, depending on how you drive it. I dont race or anything so I don't get it. Any piece of advice? Everyone go check their air filters please if you have an RX-8 and let me know what you find. If you don't know how... here!

lol Im not kidding. Its an actual youtube video of a guy replacing an RX-8 air filter.

 

I NEVER had that and I drive like a complete *******.

 

It's true, at high rpms the car basiclly spits out oil thru the hose connected to the intake.

I have the K&N Typhoon II set up, it's best to switch to an aftermarket intake, it will be a lot easier to clean than messing with the OEM. You dont have to keeo buying a new one everytime oil kicks in.

At first when I bought mine I also experienced this, it's normal, and again like mostly other say, it will depend of the way the car is driven...

 

me too

 

overfill on ur oil?

 

search "catch can" - that will solve your problem ....

 

get a catch can!

 

get a catch can and vent to atmosphere with a breather

 

or some dillhole did not use a funnel and the oil took the short route..

beers

 

I notice that on my 2005 rx-8 could anyone post a picture of this set-up?
would need more info on this issue!

 

wow never hear of this much oil heres a few pics of what the filter looked like when I got my carlook like the orignal with right at 50,000. Yes I also about took a **** when I saw mine for the first time but no oil on it.

 

i'll take the time to post some pics tomorrow..now it's 23:26 and it's frezzzing cold out there!!!

 

this can happen on early cars. Mazda changed the breather system to help alleviate this and another issue

its usually from over filling print this tsb

and show it to the idiot who said it was normal to have oil in your airbox.

also tell him to call the tech line and ask if its "normal"


also ask him what happens when oil from an aftermarket oiled K&N airfilter gets on the MAF sensor.

clean your MAF

 

yeah it def could happen but everyonce and awhile i will have alittle oil on the piping afte the airfilter to the throttle body but never any of my filter and this was only once......

 

why does the link in post 13 redirect me to the arlington parts store?

 

It's the same place, they changed their website domain a few years back. That post is 7 years old

 

the link goes to the home page though, not a tsb. I didn't expect a dead thread to give much help anyways, I'll continue the search for a fresher one.

 

Oh, I'm sorry, I missed that you were looking for the TSB.
