Thanks Srini, I have been through both of those threads and according to my SA friend in a MASS, there are a lot more such cases out there. The reason they don't come out in the open is Maruti's excellent customer service. They just replace the parts free of cost without causing any undue pains to the customer. Look at my case I have a complete new engine in a car that has done 40 - 50 thousand kilometers.

Great resolution I would say. And fair on MS's part to replace it without the fuss. And to have to pay even 5K for a new engine is not worth the hassle of arguing why.

Having said that, not very nice to know that there are lot more similar cases out there. Without getting too Ludlum on it, wouldn't this be the kind of thing that could lead to recalls and the like?

See that's the thing. There have not been enough failures to justify the cost of a full blown recall. Economically it would make more sense for Maruti to continue doing what they are at present that is replace damaged components free of cost rather than to do a recall and face bad publicity of their highest selling car.

Hmm ya I guess so. Atleast as of now.

Another thought, the cause of why this happened is not yet known, right? and it must have happened exactly when the engine was turned off. Wonder if there are any cases of it happening when the car was running. Engine shut down with the car moving would be disastrous in most situations.

Edit: Forgive me, I think I'm in a slightly paranoid state of mind today.

No idea if any such cases have happened. Will try and find out.

Hi,
Both camshafts breaking is very very puzzling.

Does Maruti use cast or forged blanks. What about Fiat?

Are Fiat and Maruti cams interchangeable. (Neglecting things like valve timing).

Yes it is very surprising. The ones that were on my car looked like they were forged, but I may be wrong about that as my analysis is only based on a visual inspection.

I don't know if they are interchangeable. Will try and find out.

When MASS changed your engine, would your engine number change?

Does the new number have to reflect in R/C book and insurance?

Thanks for pointing this out. I never thought about this at all. Will check and see what they have done. Like you have said if the engine number has changed then it has to reflect in the RC book.

This has me wondering since it mentions about there being more such MJD engine failures:

1. Wonder if these failures are in Maruti vehicles alone or Fiat/Tata vehicles running the MJD as well? This would clarify if the engine failures are tuning related or design flaw.

2. Notwithstanding the reason/good customer support, wonder why there has been no apparent effort been made by Maruti for addressing the root cause of these engine failures - since there are seemingly more engine failures as mentioned by your SA.

Supposedly the root cause has been identified but has not been shared with anybody, not even the MASS folks. This was the info given by my SA friend, but don't know how far it is true.

Most of the modern engines have forged cams. Maruti and Fiat engines both have forged ones.

While maruti has its own local vendors to procure the cam shafts Fiat has most of them imported.

Yes design is same and both overhead cam shafts can be interchanged. But i guess the spare part price of fiat cam shaft might be higher.

Engine number for a new engine does not change as per my knowledge. They tag the new engine with same serial number.

This is not the MJD engine failure. Please call it as DDIS engine failures.

There are no problems of blown turbos or camshafts on TATA quadrajet engine as its supplied by FIAT. TATA does not manufacture them. FIAT Manufactured MJD also do not have any such problems.

I guess a certain lot of camshafts were defective and were supplied by maruti vendors to them.

One of my close friends ended up with 2 broken camshafts a month ago on a swift, car had done 125000 kms , poor guy had to bear quite an expense to get the engine fixed ! There was no convincing explanation of why the camshafts broke in this case too! The timing chain had broken too - but there is no clue whether it was a consequence of the camshafts breaking or if it caused the camshafts to break in the first place!
