Continuing from earlier....
Vinayak Motors is a well sort out, well equiped workshop for multiple brands, and at a place where most of the garages were dedicated for Jeeps, this workshop was like a well for a thirsty nomad in a desert(Keeping Jaipur, Rajasthan in mind; quite literaly :-D).
We stopped the car about 100m from the workshop, i ran back and told them the problem and they offered to push start the car or push it back to the workshop. The car was push started and again the blinding smoke out of the tail pipe, i was standing at the workshop watching the mechanics push the car when suddenly a group of people ran towards the car saying "aag lagi aag lagi"(fire fire!!) I almost fell to the ground laughing and when my friend who was in the car, realised the same, laughed his heart out too
.
It was now well after 6:30PM. After the car was brought to the workshop, the story of what had happened was naratted to the mechanic and so he started with the regular checks. Of the 4 glow plugs that were changed, 1 was working and 3 were dead, they were covered with thick carbon which indicated oil in the combustion chamber, this explained the white smoke too because oil in the cylinders will give you a bluish white smoke.
I told the mechanic to check out the air-box and he was awestruck at the condition of the air-box. As i mentioned earlier, there were sand cakes in the box and the filter was in a really bad state. The mechanic immidiately said the the turbo might be at fault, after hearing the strange noise. I was amazed at the fact that this fellow knew about turbo and its functioning because frakly at a place like that i did'nt expect any of the people have any knowledge about turbos.
When the plumbing was removed it became evident that oil had entered the cylinders through the intake which was causing the smoke, as the pipes were covered in oil from the inside.
The intercooler(IC)was removed for cleaning and the fellow started to remove the Turbo. Upon uninstalling the turbo the fault was diagnosed.
The pin holding the fan of the turbo had broken and caused the oil feed(for lubrication of the rotor inside the turbo) to leak. The turbo was functioning but it was sucking in oil and throwing it into the cylinders. The fan might have been damaged due to sucking in some of the gravel from the air-box.
The real problem now surfaced and me and my friend were in a soup. Where do we get a turbo from in this place? Time was closing at 9PM.The workshop manager said said he could get a turbo with some KKK make, but he could only get it the next day
or he said he has a used turbo from an Indigo. As Delhiites we said "Koi juggard nahi ho sakta?"(is'nt there an easier way out) to which he laughed and said "Aap Dilli wale hamesha juggard ke peeche kyu rehte ho?"(why are you delhites always after the easy way out)...we laughed and said "aap Jaipur wale nahi samjhoge!!!"(You guys from Jaipur wont understand!)(actually there are different meanings for the term "juggard" in Delhi, Delhiites should easily understand, unfortunately the same cant be explained on this forum;-D).
I noticed a Indigo cab in the workshop and got a feeling that this fellow(knowing that we are in dire straits, have no options other than take his offer for the used turbo) will be pulling out the turbo from that Indigo and plonking it into ours. He offered INR 15000 for the turbo and even after a lot of haggling just went down to INR 14000 but we did manage to include engine oil in the deal. IMO we did manage a good deal in that price as a new turbo would cost around approx. INR 35000-40000 from TATA, i am guessing, but we did'nt have any option other than that at 9:30PM 260-300kms away from home, as we had to reach delhi by morning.
Anyways, the job got started and the install went smoothly, the only thing i could check with the used turbo that the fan was operating smoothly and it did'nt have any play to indicate its not broken or damaged. In the mean while, i suggested to check the entire intermediate piping of the exhaust and the end-can. The intermediate pipes were dripping oil like anything and had to be washed. The cat-con was almost choked so the internals had to be broken with a rod. The mid-muffler, kept dripping good quantity of oil even after repeated washing.
Finally the air-filter was replaced and fresh engine oil was poured, the used engine oil showed evidence of dust entering the chamber as what came out was black and almost pasty in consistency.Oil was changed just 2000kms earlier so there was no chance it could have been that burnt. And whatever came out had very little, the mechanic said that had we ran the car for more kms the engine would have surely seized, i believed him looking at the condition and amount of oil left.
