Hey Foby, thanks for letting us at TBHP know of this occurrence. It does sound a bit suspicious ... they speed at which they replaced the engine and the hush-hush manner does not inspire much confidence. I myself am looking for a new diesel and had short-listed the Sail hatchback as it is spacious and has a good ride. Now, I am not so sure any more. Hope and pray that the new engine does not give you any grief again.

What a shame for a company that once ruled the automotive world.

It is hard to digest that one of the biggest players in the global automotive scene like GM is unable to rectify an issue effectively and needs to resort to replacing the engine. Even much smaller players like Suzuki and Tata are able to provide much more reliable and durable configuration using the same MJD engine!

I feel sorry for all the Enjoy owners with low average running who might encounter this issue after the warranty has expired. Looks like they are in for a nasty shock!

That's startling! The fast turnaround indicates that the dealers have been given directives on this regard by Chevy. Warranty replacements for big ticket items ought to take more time. I too think the dealer should have informed you before plonking in a brand new engine on your car.

And please update the new engine' number in the registration certificate. Very important!

The engine is from Fiat and is reliable. But, I suspect the air intake plumbing design by Chevrolet is faulty, and hence they are replacing engines.

How they are related sir, Air & Oil doesn't comes to contact with oil each other in turbo & contact happens in the combustion chamber only. As long as there is sufficient clearance between piston & cylinders burning of oil doesn't happen.
Experts correct me if I'm wrong.

Foby -

Good that Chevy did this to you without you undergoing much hassle. Now you can enjoy the newly transplanted heart and sure your vehicle will feel much younger now!

Couple of questions:

1. Did you ask them why the engine was replaced? What was the "real" issue which caused them to silently replace the engine?

2. Did they give a reason why they did not inform you before replacing the engine?

3. How they will help you get your paper work done - RTO, Insurance etc?

4. What are the warranty terms of the new engine?

5. With new engine in place, are they suggesting you to look for indicators periodically - Other than the on-board visual indicators - like manual checking of oil level, hoses, oil drips etc.?

Have safe drives.

Enjoy the new wine in old bottle.

The GM-Enjoy was pulled out of the China factory, and the diesel engine jointly developed with FIAT was placed longitudinal to provide power to the rear wheels.

The FIAT motor is large for the available space / bay and GM thus compromised at several places to make it happen / perform in Enjoy.

The problem of premature engine failure has been observed in Enjoy while the Sail Sedan and Hatchback are not affected by this and are working alright.

Cheers !

Hopefully the parceled engine can help avert this in future.

My friend works in tool manufacturing company who are the primary suppliers for Chevrolet, Nissan, Renault etc says that if they cannot meet the demands, most of the parts are smashed with hammer and chisel manually ( in parallel to the automated assembly line ) which results in poor quality of the internals.

My heart goes out to all unsuspecting Enjoy owners who have not seen the issue yet but might do so after the vehicle is out of warranty. I am not sure if GM would be generous enough to replace engines without charge in that case.
Can it be escalated to Chevy India bosses and get some kind of acknowledgement that this is a known issue and would be dealt with appropriately even if the vehicle is out of warranty?

[zenren]

More instances of GM doing things in a hushed up manner, this time with Cruze. No official recall.

https://www.team-bhp.com/forum/india...ngine-bay.html (Chevrolet Cruze Recall in India (PVC bracket in the engine bay))

The only explanation I can think of is that the real culprits in the earlier fiasco regarding the Tavera's emissions were untouched and the ones sent out were just scapegoats.

In a good condition engine, air and oil doesn't come into contact anywhere. Even in the combustion chamber, where fuel and air mixture burn.

The shaft of the turbo with the turbines, is lubricated with engine oil. If the intake plumbing is not sufficient enough, the compressor side will suck oil through the bushes. Just like when the bushes are shot (Noticed oil in the intercooler?).

This oil is taken along with the intake air to the engine, and is burnt. After so many kilometers, the engine oil will be completely sucked through the turbo and the sump will run dry, damaging the engine permanently.

Quick update :- I have completed around 350 kilometers with the new engine and the oil color has not yet changed. The ride is smooth though.

Thanks for sharing! I can see from the thread that you're not the only one who's faced this issue. Hoping Chevy has taken this seriously! Wish you hassle free miles on it.

Earlier when their SAIL diesel twins had an issue they stopped the production for 3 months or so, GM never disclosed the actual problem with SAIL twins although it was suspected to be oil leakage. Now they have a issue with Enjoy, diesel version. They just wanted to have a diesel car on the road in no-time and plonked the 1.3L engine into these vehicles which were primarily made for petrol versions. I doubt if enough testing was done with diesel version, the packaging of components inside the engine bay also needs a re-look. They now may change engine free of cost under warranty but what after 2-3 years, who is going to bear the cost of engine replacement and will it be worth doing it?
Oil is the lifeline of a turbo bearing, with this kind of leak the turbo will blow off, a thorough inspection of air intake line can throw light on the oil leak. It will be interesting to compare the oil drain of turbo with the old and new engine, any change to the piping?

Hi
I don't think that its legal to do so. Have they(dealer) consulted with the RTO authorities before embossing the engine number. I think its another fraudulent practice by Chevy that is going to surface up in a few months.
Anyways keeping other things apart congrats for the new engine and happy mile munching.
