This is a really bad injector of mine when it went bad. Car ran like sh1t and white smoke out of the exhaust, mis-fires and cylinder shut down on all cylinders.

Hello Bucky! brother this is some serious stuff.. I should check them out tomorrow or Saturday time permits. Correct me if im worng I take them of from the plenum and just hit the ingition and the fuel pump should prime the rail any faulty injector will start oozing or spraying (right??). Defo will give this a shot. What do you think about the carbon filter theory where vacuum is created and misfire codes and fuel mixture is affected? Thoughts...

Exhaust leaks won't cause any issues post oxygen sensors, anything pre can cause either fuel trim errors or catalytic converter code depending where the leak is.
Hey brother Esteban nothing so far with the fueling components will rule out ignition components before moving next. I have ordered Tiger patch for exhaust sealing I shall seal the whole thing like no other. Its weird tho because you see with the de-catted headers the 02 sensors are sitting in a weird position way down but when checking by hand (when the car was on lift) I could feel no leaks. I have attached the picture of the set-up. I had doubts before maybe that the header connection could be the culprit for the leak but it was not the case.

Yes just take them out from the inlet/throttle bodies. Turn the ignition on and off to build up pressure, try and start the car and video the injectors, you will see them pulse and it will give you and idea. Use a light coloured cloth like I did and it should help.

Carbon filter thing sounds like BS to me.

I would definitely change the injectors, just for the heck of it, they are not that expensive anyway. Check Spareto, they deliver using DHL I think and it should be fast to Qatar, in like 5-6 days.

and regarding the charcoal filter, if I remember correctly, the charcoal filter was only fitted in US-spec cars, which I don't think is the case with your car.

No problem man
And regarding the FAMS tune, I don't have it yet, but have heard nothing but great reviews about it, all the people that got it are saying that it is the best, hands down, some people even swapped from other tuners and they said that it is like day and night difference.

I am mainly planning on getting it for the smoother SMG shifts and an added HP wouldn't be bad as well haha.

DAY 5,6 more or less

Updates guys!

So all my parts (Injectors, Coils, Sparks) shall arrive next week. Now if by changing these components the beast jumps to its feet I will be the happiest man alive! If not then move on to other components (GOD PLEASE HAVE MERCY ON ME)

So my brother bucky told me about the injectors getting messed up but isnt there any diagnostics (error codes) for this ordeal? I mean the fact that the injectors were sent to be cleaned and checked doesn't actually insure that they are in a working order is a bit of a concern :s (but bought new ones ayways- Bimmerzone had an offer all 10 for $300 over here in Qatar they 100$ a pop lool {thanks brother Seif too}).

Anyways I come to think of worst case scenarios in my head so what are the tell tale signs of failing components such as cam springs or bent valves anyone care to educate this new learner.

Also as promised attached a few images of my beast with her little sister (my mini JCW- changing the head gasket [also learning - but on mini forums lool) and some other toys.

DAY 7

Hi brothers.

SO a quick update still waiting in on parts. On digging in the forum found that misfires are common problem even when the rod bearings are on their way out. We have no blackstone labs here to do an analysis so nothing more to do than guessing.

Is the rod bearing job very intensive?

I have seen some threads but I am a little bit wary of biting more than I can chew?!

Thoughts ... Suggestions

FYI there are no knocking noises but misfires are a cause for concern.

Would it have been rod bearings then both side would have misfires. The VANOS pressure line is common. Misfires happen because the VANOS actuators would be clogged with copper swarf. But that is not the case. Now what could be the case is that your VANOS pressure is marginal. And bank 1 is the first to show the signs. And if this is the case, it is likely the internal pressure line from the VANOS pump. Measure the pressure and know what is going on.

I wouldn't jump into conclusions, but if I were you, don't try to start the car until you get the stuff that are primarily suspected to be the cause of the misfire, replace them, clear the codes and start the car, and then measure the pressure like rt7085 suggested.
