Not too familiar with the head gaskets on these cars but thats normally the cause. If your loosing coolant and there's no visible leak, its getting burned off in the cylinders.

I would think so. I would also think that it would cause the car to idle rough-ish, or feel sluggish. But I've seen weirder things.

Then again, when you're in higher RPMs, a car will usually run smooth unless something is severely damaged.. We had the same issue with our '66 Mustang until we rebuilt the carb. It wouldn't idle worth a damn, but would run like a top at higher RPMs.

Just my 0.02.... I had what I thought was my headgasket blown. I had white smoke, what I thought was an extreme coolant smell and was losing coolant but couldn't find a leak. Spent crazy money to replace headgasket and still had problem. Finally one day I saw a dribble of coolant which looked like it was coming from the oil pan and in a matter of days it was pooring out.... Finally found out it was the waterpump. Replaced that and now that I'm digging deeper I think I have a faulty injector causing me to run extremely rich. Haven't had time to check them out yet but soon will. What I thought to be an extreme coolant smell was really gas. Moral of the story just keep checking and start with the simplest things before you dig deep into a head gasket. Also never put that gasket sealer in your car. It will cause way more problems than you ever dreamed of

If you don't drive your G for days it's not unusual to see condensation dripping off your exhaust. Once your car is warmed up it will disappear, if it doesn't then you have issues....Gary

This. I also cringe every time I hear someone say, "I poured Stop Leak in my radiator to try and slow down the leak."

Based on what you said, you might have overfilled - Running high RPMs with overfilled oil can cause white smoke as well.

k guys. i really appreciate all the help i been getting here. so many of u were correct. I decided to change my oil. Oil came out blk but it didn't look like other times i have changed it. looked milkish like MADTin had said. I changed the filter 2. I stated the car and let it warm up for like 15 mins and saw that my anti-freeze had drop also. before it wouldn't. I also saw that my anti-freeze had some oil. So now im wondering what I should do first? thanks

G35 sedan w/ too much money in mods
You need to start shopping for a new motor, your head gasket is bad. It's usually cheaper to drop in a used motor than rebuild your current one. Sorry for the bad news.

Finding water in your oil, blown head gasket but that doesn't mean you need to replace the motor. Have a qualified mechanic replace the head gasket, change oil several time within the next 1K miles you should be alright. I had this happen on a Vette, replaced the head gasket and proceeded to put 180K on the engine without issues....Gary

I've been in the same boat where I had to replace my motor and headgasket on the g and it's def not cheaper to replace the motor. Replacing the motor I spent roughly 3500 maybe more including clutch and flywheel. Replacing the headgasket takes some searching because alot of local shops wouldn't even touch it cause of the wrk involved. I found somebody semi local who did the job for 850 and who specializes in these motors. Make sure u go to somebody with experience with these cars because the shop that did my shop didn't know **** about them and I'm still trying to work out issues. Good luck

Jebus, I wouldn't drive your coupe with water in the oil you'll only be causing more damage. And don't even consider using that stopleak, unless you also want to replace your radiator too....Gary
