Default Turbo emits lot of smoke and top speed has gone down

Hello All,

A problem cropped up with my Indica Turbo DLX during the past one week.

It has started emitting a lot of smoke and the Top speed has gone down drastically. Infact, in the fifth gear, the Top speed does not cross 85KM.

Also, I have to shift down to 3rd or second gear evertime I have to drive uphill.

Wondering what could be the problem.. Your help is greatly appreciated..

Heres a little bit about the car usage: I have bought the car 6 weeks ago, and it has travelled 1800KM so far. I take the car out 3 or 4 times a week, and adhere to the instructions like idling the car before shutting down.


Best Regards,
Rajkumar

Get the FP checked. Most likely bad fuel screwed up some things. Since its a new car everything should be sorted out under warranty.
Also is the smoke completely black or you see blue smoke?

Hmm....two Indica Turbo damages in a small time. Both being sparingly used.
Maybe its just something wrong with TATA's turbo

Thanks Tanveer.. As I see it while I am driving, it is black. But I will double check and let you know.

Any other thoughts regarding what could be wrong..?

Regards,
Raj

hey raj
going uphill in 2nd or 3rd is ok.........but speed not crossing 85kmph in 5th gear is not ok.....usually diesel engines are sensitive to adultrated fuel.so that could be a cause.......did u get it checked with the service station?

@Karthik, Drifter - Thanks guys, I have read thru the link provided.

@Diven - I have not had the car checked at service station yet. Will have it done this week. When I said uphill, I am comparing how the car used to behave a couple of weeks ago, and how the car is behaving now. There is a drastic difference in the pickup while going uphill..

Anyways.. After I get it checked at the service statition this week, I will let you all know how it went..

- Raj

Hi Raj,

As karthik had mentioned, I had a torrid experience with my turbo as well.

In my case it was abrupt cut off of oil ot the turbo due to plumbing leak, when the turbo was on full boost, thereby causing malfunction due to excessive heat build up.

as psycho said, your case seems o be an oil seal going kaput-hence the excessive smoke.

Also, get ur clutch cheked. Speed notcrossing 85 could also point to a clutch malfunction.

I am not too much of a mech guy- so these are a layman's observations.

If u plant to keep your car longterm, you MUST get extended warranty.

I sold mine off in sheer disgust!

Thanks Psycho and Himanshu.. I have made a note of your suggestions. They will be handy when I talk to the Tata service people.

Yes. I have taken extended warranty, and it will be handy for self or for better resale value.

Your engine oil is being vapourised in the exhaust housing of the turbo putting out smoke... It would be white if it was on your intake side, as it would lead to burning of the oil. (in this case your turbo is still working with a blown oil seal)

In the second case if your turbo has jammed and stopped functioning and if your oil line is still flowing properly then it would be that your engine is pumping in excessive diesel leading to the black smoke.

Easiest way to check is to see if you hear the turbo whine when you drive.

Thanks Psycho..

I think it may be a problem with the Turbo.

Whenever the Turbo kicks in, I hear a small click from somewhere behind the steering, and then I see the car accelerating (earlier and now also).

Now - at lower speeds, I still hear the clicking, and the car accelerating (though with a good amount of smoke from exhaust). However, in higher gears (4th and 5th), I dont hear the Turbo click sound and also the car does not accelerate further. I am only able to maintain a steady speed in the higher gears.

I will try to hear in the Turbo whine when I drive tonight.

Regards,
Raj

Try driving with the AC off...and listen for the click. I suspect thats the compressor clutch making noise. Also check the EGR valve. One friend had a similar problem and was traced back to a faulty EGR valve.
