Took it to a FNG, and he said the seal needs to replaced. He said he has to open the gear box for the same. The oil leak is from the engine I think.

Why do you think it's from engine? Didn't you ask the FNG to show the leak traces?
Also the oil falling is a bit cleaner (Gear oil) or dark (Engine Oil) in colour?

Went to main MASS (Abharan Motors, Udupi) today to check if there was a coolant leak in my Alto, as I found the coolant empty in the morning. The mechanic showed me the underbody to say that there is no coolant leak anywhere. What I saw was shocking. No coolant leak, but this part was drenched in oil.

On enquiry, the SA said that they would have to open up the engine - could be oil leaking from the tappet. (? ? ?)

New problems have been arising since I took my car for servicing in August at a MASS after many years. Now I'm not sure if I should let them fix it or take it to a smaller service centre.

Seems like a case of Engine gulping the coolant.

First get the engine oil completely drained to see Coolant traces. If the coolant hasn't leaked, its got consumed .

You need to start checking the entire cooling system - Water Pump, Radiator hoses, Head Gaskets to ascertain what has failed that resulted in coolant heading where its not supposed to.

I would prefer you to stay with the car when this is being done.

Hi Team,
My car had to go through a pothole during recent drive within the city, there was a thud sound. Now I have noticed an oil Leakage near the exhaust area. I am worried if any major damage to my car. It's a sparingly used DEC 2015 K10 , only 4K on the odo. Please guide me, pic attached.

Are you sure Oil is leaking under the exhaust area and not under the Engine area?

Oil leak near the exhaust area could be due to ruptured fuel tank. Check whether the leaked contents are smelling of Petrol or Lubricant Oil.

If you don't mind can you bend down and get an image from the actual area of leakage? The one you posted is a bit difficult to point out to.

Leakage could be from the sump drain bolt too.

Please provide a few under body pictures to pin point the source of leakage.

Regards.

The stain looks like an oil stain, not fuel stain, to me.

Check your oil pan, drain bolt and the oil filter cartridge for any damage.

If the engine area turns out OK, proceed to check your brake system hydraulic lines & hoses for any small leaks.

Either way, these are critical systems. Please get them checked thoroughly before using the car.

It is best if the car were placed on a 4 point hoist the kind used at ASCs which will allow a full inspection of the underbody.

As others have pointed out this has to be either engine oil or gearbox oil if it is leaving stains on the floor and not evaporating. In case it is vaporising then its either coolant or fuel. A petrol leak is the easiest to identify due to the smell. Please get back to us with an image of the source of leakage. It isn't that hard to get under an alto.

Hi All,
I am owning a Chevrolet Optra 2004. I have been facing a minor engine oil leak. Small droplets of oil are found below the engine bay in the parking bay.*The leak is minor that there is no visible reduction of engine oil over the past 4 months. I have taken this to Chevrolet Service center and they have been replacing components, gaskets around the engine but have not solved*the problem. My local mechanic has advised me that it is difficult to obtain parts for Chevrolet these days, hence advised me to check and top up oil regularly. He advised me that there will be no issues in doing*so rather than spending a huge amount in the service center. Is this advisable to do?*
I have clocked around 90,000 km in this car and am expecting it to keep it for the next 3 to 4 years. The vehicle apart from this issue is in top-notch condition. I have done a major service recently*including timing belt change, suspension change and is in no mind to disposing of this car even though it is 15 years old.

Why not. That's what I would do too if the leak is not significant.

But to give you a peace of mind you can still diagnose the root cause. Just do a diesel wash of engine area including under side, use the car for few days and examine the under body by lifting the car. It should show some clue. Provided you have a good patient mechanic and a garage.

On another note, sometimes these small leaks get sealed by itself. Sometimes.

Hi Guys,
I too am facing this. ( small drop of oil? in the parking area). Any idea what this could be?
Also, in the last service, my service advisor warned about coolant. He suggested some replacement (forgot what it was) which was very costly. I didn't get this done since it was not severe.
This is for an old santro. What would be a reasonable estimate?

Hi all,

There is a minor leak on the gear oil sump of my 2012 Alto K10 manual (please see photos) A few drops can occasionally be seen on the floor directly beneath, not a puddle though and not always, even after the car has just been parked after having been driven.

I could spot a drop of transmission oil bead on the seam/seal just next to the drain nut (as seen in the photo)

Any guesses where the leak is? Transmission oil has not been changed recently.
