Question about 2005 Mazda RX-8
The is no headgasket on a rotary engine....This milky substance does not affect engine performance or any other functions of the vehicle. During cold weather, moisture contained in blow-by gases (exhaust
, oil, fuel, water vapor) is cooled by the intermediate housing wall and condenses due to difference in temperature. A chemical reaction between the moisture reacts and the engine oil in the intermediate housing will yield the milky fluid. This fluid then eventually dissipates
as the engine warms up to full operating temperature.
The milky fluid does not affect the quality of the engine oil and therefore the engine performance is not affected either. Mazda has verified that the amount of moisture in the oil is within the acceptable standard for motor oils commonly found in the market.
However, you should verify that the coolant reservoir is full and that there is no sign of engine coolant leakage.
You can also go to you Mazda dealer and ask for a new oil level gauge tube plastic insert which has been developed as a countermeasure to keep the milky substance off of the dipstick (however, the substance will still be in there- it's a cosmetic fix only).

Yes thats water or coolant in the oil .
So now the big problem, can you do the job or have you got to get a workshop to do it as it could be the head or gasket..
But tell me how was it running the last time you drove it and what happened ,was it running hot/or rough/missing ???????.
how much water do you have to put in to fill it before starting in the last week.or have you been checking the oil and water every week.
DID you see any white smoke out the exhaust pipe when starting or driving.have you been loosing power when driving.
Let me know the answers to all above. RON
