The Scorpio is at FNG Kumar and Harvinder's garage (Listed in Team-bhp directory) in Vasant Kunj. Met afew Team-BHP members there today morning.
Okay so here is the update.
The head was opened, and the picture wasn't too good.
2 Valves of the third Cylender had broken damaging that piston and the head. The push rods were bent. The turbo had oil so is also damaged.
The engine hadn't siezed though. After removing the head and the damaged valves, the pistons were moving freely and with very little play.
What caused the engine to race to very high rpms, breaking the valves and doing the damage still remains a mystery. The Scorpio was serviced with Oil Change etc barely 900 kms (2 weeks) before this incident at MASS. One suspicious thing we saw was that the thermostat body had a dirty piece of cloth tugged inside. In the last service at MASS, Koncept Automobiles, I had asked them to replace all coolant pipes etc and flush and add the new coolant. It is possible, a cloth was tugged in to stop the coolant from spilling in one of the hose pipes or something. That could have stopped the flow of coolant. But my mechanics say that even in that case the engine can heat up but the engine cannot race and break valves.
For the first few years of ownership I meticulously followed the engine idling at start and stop. I have to admit that after that the engine idling rule was not followed always. But Turbo failing could also not have caused the Engine to race in this way I think.
Now the engine is is undergoing a complete rebuild. The good thing is that this engine has removable sleeves (Similar to Trucks) in which the Pistons move.
We managed to source a good condition head from Mayapuri (Second hand Car Parts Market in Delhi). We also got one piston from there.
We have got a new Genuine Mahindra Sleeve set, Piston Ring Set, Valve Set, Packing Kit, Oilseals, Tappet Bolts etc.
Now that the engine is being rebuilt we took out the fuel pump and injectors and got these serviced, and re-configured from Authorized Bosch Diesel Service Center - Guru Nanak Diesel in Gurgoan. This was the same place I had visited for the solenoid switch a week back.
The only major part to be still sourced is the Turbo Charger. I have been told that Mahindra Uses a TEL Turbo Charger. The Turbo charger is available both in Mahindra Packing and TEL Packing. The Mahindra Branded TEL Turbocharger is more expensive by 4-5K.
I contacted a TEL Dealer for the Turbocharger and he told me there were two models (Part No 53039700088 and Part No: 53049700027) and he wasn't sure which one will go in our Scorpio.
We will remove the current one and see the Part No if we can see it.
It's a decision from the heart not the head to spend a lot of money to get this engine rebuilt. My Scorpio does not have a spot of rust, and all other parts like AC / Clutch / Brakes / Music System, Tyres / Batter etc are in excellent condition so I decided to get it up again. In the last 2 years, I got new battery, new tyres, Complete AC overall with new Compressor, Cooling Coil, Condensor, Blower motor etc.
My Scorpio has been to Leh Thrice , and uncountable trips on the highways and hills. This was the first time in 12 years that my vehicle stalled on the road and I had to call the mechanics.
