Hello Gentlemen,

My RX8 recently didnt start,so i had it checked by a mechanic only to find out that the engine had mixed oil and water and i have no idea what to do with it.

i love my car and really need to get help on the way forward.Am i left with the option of replacing it with the new engine?

please assist.

It's hard to say. Do your plugs show signs of water in them? Did the car blow a lot of smoke before it died for good?

You might be in for a new engine, it's just hard to say with the data you provided.

Did he come to that conclusion from checking the dipstick?

micus

At first it showed that their was no compression at all,hence we took out the engine only to realise oil and water had mixed,it didnt blow up i just packed it nicely but when i tried to start it,it could start at all.

What were the compression test results?

micus

not really..should we look into the dipstick?How about the seals coudnt they be the problem?

Slidin8

when u check your oil with the dipstick, due to condensation it can appear there is water in the oil. but its a common known issue which isn't a problem

but if you have no compression, this won't be your problem

Does this mean that you have the engine out of the car?

In particular:

"The amount of assistance you receive is DIRECTLY associated to how much detail you provide!

So what do you need to share?

A) Break each issue you are seeing out by itself. For each of these issues, detail what RPMs it occurs in, and what RPMs it doesn't. Detail how much throttle you are giving when it occurs.
B) Detail what the ambient temperatures are that you are seeing, what the gauges are doing.
C) If you have a CEL, GIVE US THE CODE! (most auto-parts stores will pull the code for free for you. Otherwise, you can buy a code reader for LESS than the dealer's diagnostic price, giving you a discount on that one, and free code pulling for the rest of the device's life, across every car you own) (Hint, search with Google and site:rx8club.com <CEL> before posting. You will probably find your answer.)
D) Detail any possible modifications or repairs that have been made within the last 3,000 miles, even if it seems like it's not related.
E) Detail the age and mileage of the car, and what maintenance history it has been on. NOT just "it's gotten regular maintenance" because there are wear items that are not part of "regular maintenance" for dealers and most shops.
F) Since many issues are ignition related, and you are going to get asked, give us the mileage and age of ignition coils, wires, and plugs.
G) Detail out when it DOESN'T happen. This is just as critical as when it does!"

You have not provided enough information to be useful in guessing what's wrong.

^.................Got that right. Severe lack of info.

If the conclusion turns out to be the water seals, you will need an overhaul. Just by reading your post and the other members comments.

If you are mechanically inclined or really curious, i would pressurize the motors coolant system to 13-15psi and see if it holds pressure. If it loses pressure you can try to find leaks... will need lots of light and cleaner. I wouldnt recommend going over 20psi or you can cause unwanted damage.
