Even I plan to do the intake manifold and EGR at FNG. They do the opening and refitting, I and another BHPian do the cleaning and general supervising​.

I don't visit MASS for all these jobs.

Hi a4anurag, I had this doubt, will cleaning the EGR valve and the EGR coolers along with it make any difference in the engine performance? Yes, i understand Nox will come down, but the rest of the parameters, say like pick up or smoke or engine noise etc? There is lot of demand for service providers for EGR cleaning in maruti ASCs , but I always wondered why they push for this service when customers complain bad pickup or smoke.

Saw these aids used in our campus to check the leak rate from the injector. These are being developed for OEM's and are prototypes for the moment.

The below ones are more accurate than the above apparatus. The hoses are all calibrated ones and the cavity itself have been marked accurately. I could not see the actual way in which the leak rate is measured. If I have anotheroppurtunity, I will share here.

I wonder why nobody have mentioned "SF 16 Seafoam" in this thread. It is an all in one solution, cleans not only the injector, but also claims to take out carbon deposit in your cylinders.
It is an internationally used solution, however is a bit more costly in India.
It has a lot of positive user reviews and you can see how it does the job if you go through youtube.
The best way to clean any injector is always to dismantle and use WD40 or any injector cleaning solution manually. But for the people who needs an easy fix , Seafoam does the job.

Showed this thread at FNG and performed injector cleaning for my friends swift.
As you pointed out rightly, the plastic T sections are very delicate, trying to remove one carefully, broke two T sections.
Just a hint to disconnect is, rotate pipe - clockwise and anticlockwise while applying mild pressure to pull it out. Just pulling it out, without rotating would break it.

This T section is not available individually. It comes as a set of four with hoses connected and costs around 1600Rs.

It should cost max 500Rs, for terming it reasonable.

Update to my previous post.
Maruti has updated the spare quality, with respect to return T sections and it's made of metal now.

People can buy for their quadrajet and Punto mjd too.

Below are the pics and now the price is justified.

Hi Anurag,

It looks like my Ritz has some problem releated to fuel/injectors. There's very bad diesel smoke smell at idle and also the engine sounds very rough inside the cabin.

MSM Chennai is suspecting that the injectors have gone kaput and are asking me to replace them at a whooping cost of Rs 15K per injector.

I was discussing about this with Parag couple of weeks back and he suggested me to use Liqui Moly diesel purge first and then change the fuel filter.

So, my question to you is, can I empty Liqui Moly diesel purge onto tankful diesel during my next filling?

Firstly, you don't need to replace the injectors if they can be removed, tested and re-calibrated and that is POSSIBILE.

Liqui Moly can be used by directly mixing it in the Diesel tank as per directions mentioned on the can itself.

For extreme cases, there are other methods of connecting it to the Fuel filter lines but that won't work due to insufficient pressure.

A Single can of LM can be used for 2 full tanks. But if your issue is extreme, use a can for half tank and it will still work. There is absolutely no hard and fast rule here and it all depends on how badly are the injectors clogged and there are cases where people have fed LM in place of diesel and run the engine till the can emptied. Hence, concentration percentage is not at all required.

This is a brilliant thread that explains the whole injector cleaning process. Please refer to that for more information.

Also, MASS won't do the cleaning for you. They will only remove and fix the injectors back. Once they remove the injectors, they will take it to a reputed Injection system agency to get these cleaned and re-calibrated.

If you can find out the best ones in Chennai (Like Bangalore has Swamy Diesel Injection systems), you can directly call and ask them. Since they deal with this business day in and out, they may also suggest you an ASC or an FNG that can confidently remove these injectors for you that MASS often tries not to fearing that they may get stuck during removal.
