Hi,
have searched forums, but was wondering if anyone could tell me if these symptons are related? i bought my 04 rx8 6 months ago, i noticed the check engine coolant light coming on wen i drove at speeds over 50mph, then only yesterday i checked oil and it was creamy like baileys, i read on here that is pretty normal in cold codnditions, but i topped oil up, went for a drive and the CEL light come on??
Cheers Grant

Well, regarding the check coolant light - I am assuming you did check the coolant, right? All levels normal?

The frothy oil is normal.

How is the power? Pulling hard all the way to 9k? Hesitation? Flashing CEL anytime? Any odd smells? Exhaust, glowing cat, etc?

With a mysterious check engine light, its worth a trip to autozone and have them pull the CEL code. That would be the next thing to do.

How many miles?
Auto or MT?

ad a little coolant. get the code

If the coolant level was OK, there is a thread in the Tech section about the coolant sensor in the overflow tank failing. Replacing the whole overflow tank is the only fix (~$150), otherwise just disconnect the sensor and keep check on your coolant during oil level checks.

Milky oil has been covered at length, normal at cold temps and does not harm engine. Agree, get the code pulled more than likely gas cap (I've been thru 3 on my 04), but you need to find out what it is.

Yea checked the coolant, all fine. pulling hard all way till 9, but on motorway yesterday when the CEL light first come on power did seem to reduce alot seemed like it was almost going to cut out and CEL light was flashing. exhaust not glowing or anything, but is blowing a bit maybe baffles? the car is manual and 47k miles

many thanks grant

CEL flashing means a miss fire... I know you've only owned it for 6 months, but it may be time for new plugs first... then possibly coils.
It will flash until the miss fire stops and then it will go back to solid.

Pull the codes for sure now.


... However, that has nothing to do with your coolant light... Its possible the coolant seals on the rotary housings are starting to leak... BUT if that was the case, you would notice a TON a white smoke from the burning coolant and dramatic power loss.

+1 on replacing the plugs. Try replacing the plugs, coils and wires. I had a similar problem but went away after replacing those 3.

yeah pulling hard cel flashing = misfire

Hey guys, just took it out for a spin, not loosing power at all now and CEL light is solid, but when i hit around 4500rpm there is a noise like a grinding bearing , it gets louder and louder, and when it slows down it whistles/high pitch whine any thoughts??

get the code

Dude... not to be rude, but if you were out driving around, again... why didn't you stop in someplace and pull the code? Problems don't just go away with time.

Wait.....wait....is it me, or did someone already say "Get the code" ? :uhh:

^yeah u need to get that code pulled or u will never know what is wrong with the car....

Sorry guys,
haavent had code pulled up yet, as its £82 and dont get payed til friday :D, but wil get code fri and go from there. Thanks for all your help i do appreciate it
Cheers

What does getting paid have anything to do with getting the code pulled?
Places like Autozone will pull it FOR FREE!

well i'm not sure ur area where ur from but seeig ur not from the US I'm guessing u don't have like Autozne or Advance auto? If you do it's free there!

Uses the term "Motorway" and speaks in terms of money in "pounds", so I'm gonna guess he's in the UK.........my dear Watson! :)
Probably doesn't have an Autozone handy! :uhh:

Grant, it does help a little bit to add your location to your profile. You may find someone close by will pop in on this thread and offer to read it for free........but not if they don't know where you are.

So how'd I do anyway?

^yeah that's what i was figuring but i didn't know if they had like autozone around those parts or somthing of the like.

Right... that's why I said places LIKE Autozone. ;)
Not sure how things work outside US.

Oh Bloody Hell.....there has to be something of the sort! :eyetwitch

It would be rubbish to think otherwise

oh bloody Hell!!!!!!!hahahaha

^ you guys are stupid. :lol:


I would limp the car only IF you must drive it. Otherwise, I would find other transportation if you're able.

"Take the tube, mind the gap, good day!"

Cheers guys, i would take it to autozone but as Mazurfer (http://www.rx8club.com/member.php?u=32297) guesed im not from US wish i was by the sounds of it, getting codes read 4 free sounds gd :D no places like that here in England :( well not that i know off. No where seems to have a clue about the rx8 except 'only local mazda garge' lol and they want £82 just to pull the code up!!

England doesn't have any auto part stores that you could call and ask if they have a reader?

Jeez....at that price, I would buy one online from the US and have it shipped. It would still be less than what you're talking. Of course you could get a fancier one, but check this one out. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=94169 Even with shipping to the UK, you come out ahead and be able to at least read your codes from now on. If they won't ship, and you wanna pay me, I'll buy it and send it to you! I have one of their stores about 5 minutes away. Oh yeah....then you can charge other people to read theirs!

brilliant, didnt realise they were that cheap, found a few on ebay for nice and cheap :D know this is going to seem like a silly question but how do i go about reading the code? like where do i plug it etc??
many thanks

MADE IN ENGLAND

Get one in your own country for about as much as the dealer wants to read yours.

The OBD-II port is right under your dash near the steering column.

Once you get the code, go to this link to see what it means:
