996tt Smoke when booting it hard?

[911habbit]

Is it normal if you boot away to see some smoke left behind at the lights? Once at speed you can't see any.

What should the oil consumption be on average for a 996TT?

Any experiences welcome - thanks.

The car is a 2001 996tt with 22k miles

With our M5 at speed if you are behind it and the M5 floors it you see a lot of black smoke.

However i have never seen any on our turbo. We ahve 15k miles and oil consumption is very low.

all the best

Is it your clutch? In which case it maybe up for replacement sooner than you think. Doing trick standing start stuff in 4wd is HEAVY on clutches. THey wear just like tyres.
I note we should report abuse!

My 2003 tt got through 3 ltrs of oil in the first 2.5k miles... since then it's calmed down to about .5 ltr per K

Never seen any smoke though... OPC visit I guess?

Using about 1 quarter of a litre every 1,000 miles. Only get smoke when starting engine from cold, especially when the car has been left standing for a few days (this is normal though).

Our boxsterengine gives the same, smoke from a cold start, really quite a lot if it's been left for a while. Never had to fill the oil though.

Adam, just a quick warning: I just took my M5 back to the dealer for the same problem - turns out the bores were worn and they replaced the entire engine block (and pistons) for a total cost of just under £9K.

All covered by the warranty .. which was nice.

Apparently Esso/Shell/BP (the service chap couldn't recall) were selling some dodgy petrol a while ago which caused this problem.

Thread hijack.

futie - if the service chap was correct, I'm not convinced BMW would have stumped the full cost under warranty...smells a bit funny to me.

Whilst bad fuel can cause all sorts of maladies, it's not uncommon for manufacturers to try and point the finger elsewhere.

If this were the situation, there must have been tens or hundreds of thousands of people affected on all sorts of marques. You'd have to be very unlucky to be the only one hit, and I'm even less convinced that BMW would stump up multiple hits of multiple kGBP rebuilds...

Can't disagree with anything you say, Andy. Certainly seems odd.

V8 engined BMW had nikasil bores which was affected by the a relatively high sulphur content contained in some petrol sold on forecourts in the late '90's - the sulphur cause the nikasil coating to wear away.

The same prob affected the early Jag V8 engined cars which also had nikasil bores.

Both Jag & BMW had to replace a good few engines under warranty - accepting warranty claims for replacement engines up to 100k miles on affected engines as long as it had been serviced within the dealer nework.
