Strange "gunk" in Oil or on Dipstick - Info/Questions
#277
I'm new to this with my son's '04.
I'm also fresh off a intake gasket repair on a 3.1L Chevy with Dex Cool disease.
Just did an oil change today and hopefully, with the summer months ahead, this will get better.

Milky Oil
I Have 2 RX8's a 2004 230 and a 2006 Evolve both have the same problem making it hard to read the oil level until the dipstick has been taken out several times and cleaned.
I took them to my local mazda dealer who told me to take em out on a long run and hit the rev limiter a few times. Too many short runs of less than 100 miles causes condensation in the engine which he reassured me is quite normal!

Hi im new to the site and have had the gunk problem since i purchased my 2004 RX-8 in may of 2007. I had no other problems til this winter. I've noticed the smell of coolant after I take the car for a drive, even on shorter trips. If i get it to temperture it always smells of coolant. There is no visible leak that i can see on the ground or anywhere else. There is also a brownish tint to the coolant in the overflow bottle, which i assume to be oil. The other problem i have is when idleing at stop the rpm's go down close to 500 and nearly kills the car. Other than that it still drives well.
Any suggestions or tips?
Also i was wondering how i can tell if the recall work has been done. There is a green streak of paint on drivers side door, and also on enginge cover there is a white 18K and a yellow
B18-1. Does that mean anything?
Oh and car has 51013 miles on it now. In 2007 it had about 42000

Hi All,
Am a relatively new RX8 owner - have a 2005 231 and absolutely love the thing.
Was alarmed recently with the creamy gunk I have noticed on my dipstick, which seems to fit the pattern a lot of you are experiencing.
Haven't yet seen a resolution to the problem - do I ignore or should I take some action?
Many thanks in advance

As I recommend to all that ask about the dreaded CGOD (creamy gunk on dipstick); Run DO NOT WALK to your nearest dealer and BEG them to run procedure MNAO; 010.234b. This is critical for the health of your motor. If the synthetic hypertrophy initiated in the CGOD formation reaches your rotors, your seals will swell and displace the apex springs.

As for your CEL and shaking, that's not normal at all and I would recommend pulling the code for the CEL and/or getting your car checked out in detail.

I had the same issue while living in Saratoga Springs, New York . I saw this white milky substance and somewhat freaked out when i saw it. At the time it was around fall/winter. Highest temp i saw was 65F lowest was around -5F o_O. I looked online for some sort of resolution and sadly i didn't find any. Partly b/c i was way too busy at work. Then i moved to San Diego and no more milky substance. approx. 30k miles later no problems with the engine. So I would suggest a warmer climate. ; )

There's only two sure bets:
- Move somewhere warm
- Modify your PCV Valve. This prevents water condensing in your oil in the first place

Usually happens when weather changes from warm to cold
I did also see this on the oil dipstick, however the temperature dropped from 16 degrees Celcius to -2, in two days. ( Yes I'm from Sweden )
Ofcourse it doesn't have to go from warm to cold, but that could also be a reason. I would think that the difference between the temperature during the day compared to temperature during night is the bad guy here.

Having been alarmed by this problem earlier today and (after getting my heart back into my chest) finding this thread . . .
If this is true, perhaps taking the oil cap off after a long drive would help get the water vapor out?

It might help. But I would think you're just as likely to allow more to get in. Feel free to try it and report back though.

Thank you for searching frezik
You get 10000 internetz.
Taking your cap off may or may not make a difference, but it's a waste of time. The milky **** on the dipstick isn't gonna hurt anything. It just makes checking your oil take longer. An insulated dipstick tube would make the problem go away, but it more work than it's worth imho. Just make sure you check and change your oil consistently and you'll be fine.

I actually found gunk on my dip stick for the first time today. Its weird because in Houston ive always ran 5w-20 (old and new engine) and the only thing ive done different is switched from 5w-20 to 5w-30. Same area still. Yay i guess

My RX-8 has had this issue in the past and present. My theory is that it is merely caused by cold temperatures, warm up time or not, completely full or half empty oil, it just doesn't like the cold much, so it foams at the mouth.
#299
Me too!
Sure could use some reassurance here.
I backed my 8 out of the garage and did the fog light rewire. I started the engine a couple of times to make sure I did the for light rewire job right. I waited about 10 to 15 minutes and checked the oil level. I pulled the dip stick out, wiped it, re-inserted and pulled it out again. The dip stick had white foam with the oil all over it. I did the procedure again with similar results. The bottom bent end of the dip stick had a drop of foaming looking oil on it as well. The oil smelled like it had gasoline in it. The outside air temp was around 54 degrees.
The 8 has about 1500 miles on it. Oil level was 1/2 quart low. The car had been driving 24 hours earlier.
I would suspect if I were getting water into the oil the oil level would rise.
I'm hoping this condition is caused by cool temperature and no warm up.
Can anyone out there help?
