Hi There....I've got a 2003 911 TT with 68K miles on it. Lots of go fast goodies including larger Turbos. I've only had the car a couple of months but noticing it's using at least a quart of oil ever couple of weeks - say 200 to 300 miles of driving. Does smoke sometimes on startup but not always.


Runs strong and otherwise seems great. Thoughts on the high oil consumption?

Thanks

I have no idea what's wrong with your car, but if you're at 200 miles between adding a quart of oil then something is definitely not right.

Whens the last time you changed your oil?
Thats a lot of oil.
When i run twisties everyday for 2 weeks straight in 90 plus weather For an hour or two i burn through a quart in 600 miles. Im switching to kevins recommendation before i run backroads soon..
I notice more burning at the around 5k miles since an oil change.

Fwiw im bone stock.

Also how is your driving style?
Do you do a lot of rolling runs or dig runs?
Cool your turbos down after driving?
I only ger smoke on start up when i turn the car on
After moving my cars around hot and cold engine.

As Dock wrote, something is not right.

I would guess the oil seals in the turbo bearing are shot. Are you getting a lot of oily shooting on the exhaust tips? Aer you sure there isn't an oil leak somewhere?

Checked for leaks? Sounds like if it is burning it could be the turbo seals.

Carlo_Carrera

Usually if the turbo bearing seal wears out you get seepage in and around the turbo unit. Thus, check for leaks.

Perhaps a bad PCV as well? Pressurizing the crank case?

How full do you keep it? Right at the top? 1 Bar down? 3 bars down...etc.
When do you check it? Hot after a good long drive?

Carlo_Carrera

Maybe, but I think if the case was being pressurize to would trigger a check engine light and throw codes.

Turbo bearing seals are one of the few things I can think of that can go bad, burn a lot of oil, and not throw codes, at least initially. Valve seals might also do it.

I have the exact same condition
did you ever figure yours out ?

Pressurizing the case or turbo seals would make it smoke.

cerex

I have no smoke at all, some slight white smoke at start up no more than i had on C4S for 5 years that never ate an ounce of oil

there are NO circumstances in which this might be considered normal. I'd be looking for puddles.

cerex

Taking her in next week for diagnosis try to solve the mystery agree not normal at all

I have small dribbles here and there but we are talking drops nothing that adds up

your car ( no car ) should visibly leak oil. turbo seals is a possible but wouldn't nearly account for the type of loss you describe. GL with it. you need to get it on a lift etc.
