If it breaks at idling speed or very low speeds there is a possiblity that you may be saved from the costly repairs such as damaged head, camshaft engine valves, pistons etc. But if this happens at high speeds then it really damages the engine and you are in for a a very high cost repair job.

Do you remember at what speed the engine stalled ?

The general practice after the timing belt is changed, engine is rebuilt or when you refit a FIP the technician must rotate the engine manually for one complete rotation. This is done to ensure the timing is correct. If the timing goes wrong then the engine locks at a particular point when the piston and the valves touch each other. In your case if the camshaft is bent and the head is damaged how could they start the engine ? The engine as I told you just wont rotate fully if the camshaft is bent. Even your regular advisor is also amused at it. I would suggest you to tow your vehicle to Bangalore and get it repaired at your trusted place.

Keep us updated.

I understand that when the head is removed/replaced one also has to replace piston rings and/sleeve else it results in loss of compression over time resulting in engine oil consumption. Is that correct?

No it is not cumpulsory to replace the piston rings if you remove the head. Suppose you have a blown gasket. What would you do ? You just have to remove the head change the head gasket and thats it.

One thing important here is the correct thickness of the head gasket. If you dont get it right then there will be a big change in the firing of the engine. Even a lay man can feel the difference in the engine noise.

It wont have any loss of compression resulting in early engine work.

My Safari Dicor 2.2 VTT brokedown in the middle of the night during travel 2 weeks back. It wouldnt start. Finally I got it towed to the nearest dealer Manickbag in Hubli which was around 70KM. I am told that Timing Belt is broken and needs to be chaged.

Did you get the retro-fitment exercise done , which was taken up by TATA 2+ years back on initial 2.2's. ?

My safari dicor 2.2 is about little less than 20k on the odometer. I had changed the oil when it was at 10K through the service centre.

want advice if i can procure synthetic oil from outside? and ask the them service outlet to use that? is that possible?
else can i do it outside, if so what engine would one recommend for the safari 2.2 dicor?

thanks in advance

You can use Mobil Delvac 1 (API CI-4/SAE 5W-40) that exceeds what TATA recommends for 2.2.Since the oil exceeds the specs needed,I don't think TASC would mind.

It is not about exceeding specifications, the reason given to me by A.S.S was that unless the oil is sourced by them, it cannot be entered into the computer and hence will come in the way of warranty claims.

A lot of 2.2s had timing belt snap issue. Tata issued retro(timing kit and gear complete change), and most 2.2s got it. If your vehicle somehow missed this update, you can probably ask customer care to give you some discount. However, the current TASS may be taking you for a ride, take the vehicle to your trusted service center, and see the damage.

Thanks for many advises. Some answers below:

- I was at approx 70 km when the belt snapped. I could not make out at that time and the vehicle continued to move for approx 30 meters before stalling.
- I did take my safari for retro fit which was I think 1.5 yrs back. I don't think they changed timing belt though. They loaded new ecu sw and ecu cover.
- I have done all my servicing on time and also did a check 1 month back before I went on long drive. All in prerana motors. Now I m confused which is worse... Tata product or their service.

All this while I was putting up with small issues since my love for safari was too much. But after this I am never going to buy another tata product.

Also can anyone confirm whether timing belt should be changed before 1.05 lakh km or 2 year whichever is earlier? That's what the gm is telling.

Its only on the running KM's as you have mentioned and not on the years. Go through your owners manual Pg 146, Service Schedule, timing belt needs to be changed only after 105000 km along with the sedimenter and there is no mention of 2 years for these two items.

Hello fellow safari owners,
I recently serviced my "Dicor 3.0" Safari, which has covered 140K Kms. I serviced them at Concorde Bangalore. Usually I service them in Coimbatore, but just thought I will try some other place. My service request were to do a oil service and also fix timing belt, water pump and recalibrate fuel pump. But the SA advised me that the 3.0 ltr does'nt have timing belt and they have timing chain. Which I was not clear about at that time. But later confirmed from this forum.
I am puzzled by the fact that the 2.2 ltr which is an update of 3.0 went back to timing belt. Can anyone confirm if the 3 ltr has timing belt or timing chain?

Regards
Prem

Folks got the delivery of my Safari last friday, the truck came with 68kms on odo and have managed to take it to 331 on weekend.

Noticed couple of things:

- Whats the rpm i need to maintain in 4th gear? noticed that a weired sound, something like a tapped noise if i drive in 4th in 2k rpm, the same does not happen if the rpm is around 2400. 3rd gear is very happy at 2k, is this normal?

- Engaging reverse gear and first at times is hard

Congratulations on getting your Safari.
Show us some pictures of your truck.

Yes. It is quite normal for the engine to protest when you lug it in any gear. After the running in period is over , she will become more 'eager' at higher gears. But until that time, try to maintain her at around 2500 rpm.

They are right, 3.0 is a timing chain.

They havent gone back since the evolution is from Timing chain to Timing belt. The chain makes more noise & vibration but is more robust. But 3.0 ltr engine was a redesigned 407 engine and therefore the chain.

[lohithrao]

Thanks Prowler, sure will post some pictures soon.

Because of the traffic i was forced to stick to slower speed, ultimately ended up driving in 3rd ear at 2k rpm for most of the time.

Dadu the 3.0 Dicor has gear timing. Actually the engine is the same as the Spacio Engine which has been worked on by Tata Motors into a common rail engine.

The 2.2 version by designed by AVL for Tata Motors and is a very advanced engine with twin cam 16 valves VGT etc.

thanks for the response to my query.
At this time i may have stick to the service outlet oil change, since they dont make an entry in the records if I purchase the oil from outside.
That might have some impact in warranty if there are any problems.

thanks once again
