So today after someone's suggestion to check out my MAS I decided to take my entire air intake apart (stock one that is). Reason being I've been getting pure shyt gas milage. I found a DYI about removing the airbox and away I went.
And this is what I found

So after all this I realize my service dep are filled with bloddy idiots!! The Pepsi bottle is filled with oil that was in a run off thingy lol

Ouch, that hurts.

Looks like you have a 2004 or 2005, they have the old crankcase vent setup.

The new system sends oil mist thru a PCV valve to the very bottom of the intake, just before the engine. Our "old" system vents right before the throttle plate, without a valve.

It helps if you install an oil "catch-can" in the line that goes from the top of the oil fill tube, it will knock out all the liquids.

Mine looked the same oily mess as that back in 2004.

Oh, and don't forget to clean off the MAF sensor, or you will get TERRIBLE gas mileage!

davidwanj

how bad are your gas mileage? I don't know if I have the same problem or not, but I do notice I have less then what it used to be

Clavius

Around 9.5-10.5miles per gallon. Whoohoo..!! bleh.

Stealth gonna be sending you a PM man.

Hmmmm........Interesting. I should check mine. My mileage is shitty compared to my normal, but we are on the "winter" gas which totally sucks anyway, although it's sucking worse than last year by about 2 MPG. Is that oily mess something that is caused by over-filling the oil???

I used to think it was an overfill problem, (and subsequently chewed out my service manager, and got a replacement filter for it) but it happened again, and clearly originates from the flow of engine gasses at high revs.

Since I put on a catch can, it has caught about 50ml of oil, and the intake stays clean.

^I'd have to say a big yes on that. The Amount of oil I wipped off and out of the intake was way to much to be blown off and considered mist accumilation. Id wager about erm.. 1/4 to a 1/8 a quart of oil atleast througout the entire air intake. Note the Pepsi bottle all that luquid came from the pastic peice next to it. Oh also I myself havent added oil in awhile and I noticed when the dealer last had my car my R-Magic Oil Cap was moved and hence must of been taken off (I made sure to position the cap when on fully to point directly forward so you could read the R-Magic logo hehe).

Sadly I just found out our "Filter" is a special order only so no real auto-parts stores normaly carry them Tomorrow gonna take my baby for a small spin and maybe go to the dealer and pray their parts dept is friggin' open (with my luck they wont!).

I could always have them check it out since I have to take mine in Monday anyway to get one of my TPMS sensors replaced, since I have the blinking light and sensor #2 is the culprit. If I can manage 450 more miles of driving before Monday morning (piece of cake) I will also be due for a tire rotation. Of course I would still like to see for myself, though.

I had thought my mileage was improved after the spark plug was tight again and I ran the treatment through the tank (almost finished with the second tank of it with one without in between, as recommended) since it went up to 20.16 and then the next tank (which included all my snow and freezing rain driving [which took two hours to drive the 19 miles home from work]) was 19.66. This tank right now is looking to be low 17s, although the car is still running good for the most part. The only thing different is I got it at a different gas station this time (the one closest to me on the way into town, instead of the 24-hour one on the way home from work). It's probably just the gas, but since dropping mileage was mentioned, it is at least worth checking into just in case. I've got a little over 9500 miles on my 06 right now.

I had close to the same thing on mine a while back. Guess it wasn't caused by the K&N filter.

I installed a catch can and haven't seen any either.

One of our local club members was over to do some maintenance and mods. He had the sitting oil in the flexible intake pipe as well.

The new TSB for milky substance on the dipstick is the fix for this.

Anyone know if a catch can is better than the PCV setup for NA or FI?

wankleman

Is there a DIY on the catch can?

Raptor75

There are a couple of good threads on catch cans and it is very easy to install.

As to the problem, I had the same thing happen on my late model 05. My air box looked worst then that pictured, the service manager told me it was my fault (isn't it always) because I was filling the oil with out a funnel. They cleaned out the air box but didn't replace the oil soaked air filter, nice work Mazda. I bought a catch can but decided to hold off and see if the oil re accumulated and if it dose I plan to make Mazda put on the new engine venting system. I'm sure I'll have to do it with them kicking and screaming.

My gas mileage also sucks and I don't know if Mazda cleaned the MAF when they cleaned out the box, based on their **** poor service my bet is they didn't. I'll have to clean mine out.

DOMINION

I might be wrong but, If I recall in the Probs section someone said they had this same prob and the dealer would fix it for $3,000.
So I'm I wrong?

Clavius

Your right Missy I aint having the best of luck recently, obviously my dealer is filled with a bunch of friggin' morons. Thing that sucks is again I ended up breaking off the right bottom piece 'cause the grommet wouldnt let it go at all, oh that and the left bottom side had no grommet at all! Meaning the ******** when they last replaced my filter lost it and didnt replace it.

And Dom I hope/pray your wrong about that 3k fix. Gonna find that Catch Can DIY and might swing by Home Depot today. That is after I goto Advanced Auto Parts for some Brake Cleaner (thanks StealthTL!) to clean out my MAS properly.

Raptor75

e-bay has a lot of catch cans for sale cheap.

Clavius

So yesterday after a failed attempt to find a catch can or something I could modify into one, I decided to atleast clean off the MAS. When I did so and upon lifting it up and out I looked down to see before me yet another stream of oil in the piping. Needless to say I muttered some four lettered words out loud and said to myself afterwards "Screw this they are fixing this!".

I took my pictures I took of every step I took of cleaning to the dumbass dealer and told and shown both the service rep and the service manager what was going on. I told them that last time I took the car in was for my CEL which they ended up replacing my CAT, and that I noted how my oil cap was moved (thank you Lazi for that R-magic cap btw!). I got a look from both of them of "uuuuhh...... doh!". I told them of my **** poor milage (9.17mpg last tank thank ya very damn much woot!) and how I believe this to be the possible main culprit of it all.

Tomorrow I should hopefully get a call from them explaining what they are going to do. It better be damn free 'cause I sure as hell didnt cause this problem grrr... ok Clavius breath.. breath..... ahh.... ok back to a minor rant. If they tell me sumthing I dun like on the solution going to tell them I found sumthing (the previous posted TSB) and I'll be down in a few to drop it off.

I could understand a few droplets here or there but even the service manager said upon seeing this picture.

"Yeah the engine injest's oil naturaly but that yeah that aint right..." he likes to say Yeah alot I've noticed in the few times I've talked to him lol.. nice guy he just works with morons.

Add on: Also forgot haha this I found kinda interesting. As I was leaving to wait for a rental the Service Manager said to me "And thanks for investigating this helps alot." It wasnt sarcastic or condensending if anything thankful really. I have a feeling his Rx-8 service scores have been miserable (wait till MNAO gets my survey for my CEL/CAT issue... he aint gonna like it).

Hmmm . . . didn't you get the memo?? lol.


Stealth - do all 05's have the "old" crankcase vent setup?

StealthTL

iTrader: (1)

I don't know where the cut-off year is - the 05's have the old pipe and some 06's have the PCV and manifold piping, but they may have switched mid-year.

It is easy to tell which you have, the nipples on the passenger side of the alloy intake are just capped off if you have the old vent pipe 2005 system.

swoope

and there was a tech article for the dealers for retro fitting if the car had a problem.. i would mention that...

beers

Clavius

Thanks guys.. tomorrow when I call 'em up I'll mention the article. Hopefully I wont be blown off (again) and told something akin to "well if you fall within the Vin range..." I mentioned the problem about my door sil rust reoccuring and how there is a TSB for it (hoping he or someone would look it up to properly fix it) and he gave me a slight attitude 'bout it. Mind you I brought this up nicely and no ego whats so eva in my voice. Just repeated "well if you fall within the vin we'll look into it..".

Once they fix their mistake its done. I highly doubt if I went to another dealer and mentioned "yeah this other dealer messed up fix their problem" I'd get it done there.

dmc27

Thanks. I'll take a look.

GL Clavius.

Ahh just got it back they cleaned or rather recleaned the entire intake system replaced the filter, drained the oil and did another oil change and filled it to proper level. Its dark out right now so I can't verify the entire cleaning till tomorrow but so far when pulling out I definatly felt a improvement.

Acceleration wise butt dyno says I unlocked a few more previously locked away ponnies. I'd wager 5-10 atleast nothing drastic but noticable. Car sounds a bit cleaner to when breathing in.

Downside the mentioned side sill rust issue seemed to of been ignored. Oh well Just gonna bring my business else where. And while there I'll have them look at my motor mounts, SoB was shaking like I have a V10 unda the hood while at a stoplight. Soon I shall have my baby fixed right.

Mind you any post's I make about issue's with the car are not bashing the car nor have I really complained about the car but more or less about the dealer I've been dealing with. The car was previously a Corporate Lease Vehicle which means some GM or some form of Company Rep drove the car for 2 1/2 years got it to 31k and gave it back. I was told by a few people Corporate Lease Cars are the best since all the maintence and care are provided for free so there is no hesitation upon bringing it in (re: lack of money). So far this myth for me is soo busted (someone drop down the Myth Busters sign of Busted right now will ya). Its been slowly nothing but problems minor ones thank the gods but issues none the least. Wish I did a dyno run this past summer so I could compare it to a dyno run this coming summer to see how much hp I've unlocked.

Next Mod though is a catch can that is for sure. Oh and..
Thanks guys ya Rock for helping me out!

Hey Gang.
I have had my 8 since 8/04 and have tinkered around with it since the beginning. This problem never existed in my 8 till just around the 30 grand mark. In fact it was only days after my 30k service; I was on the parkway Christmas eve with my rpm’s around 7 grand and the engine just started breaking up. The engine light kicked in and after taking my foot of the gas and costing in neutral the light went out but it would continue every time I brought my rpm’s up over 6. I felt like I was running on half my engine. At first I thought it might be plugs and wires but when I took the air box off I found the exact same problem I see in Ur pics.
As far as I’m concerned, this isn’t an existing problem, I would have seen it … this is new and I am pushing my dealer for a total fix.
Today I dropped it off. They haven’t had a chance to look at it yet but I will keep U informed of events. where could I get my hands on that tech artical?
Regards.
Grey
