Awesome and thanks!! How many o-ring kits did you go through? I was told you only need to change if they rip and did you order OEM injectors?
I'm not sure what you mean by o-ring kits. I replaced the injectors with OEM injectors. It's expensive but something as important as fuel delivery should not be skimped on.
I also replaced all gaskets (upper and lower manifold and throttle body) if that's what you're referring to. Injectors should come with all seals. I hope that answers your question.
So after the cleaning unfortunately I don't feel any extra power, which is a shame. The only difference is when flooring it around 6k RPM there's still some power left, whereas before it sort of was revving for the sake of it. Guess it makes sense as after a carbon clean you can push more air through. Fuel economy is slightly better, which is a plus. Anyone else care to comment on their before/after experiences?
Exactly the same for me.
It's much more easier (for me) to proceed like this :
- Unscrew these 2
These are screws 3+4 on this drawing on which the engine is seen from behind.
To separate the 2 parts, unscrew (not completely, just 2-3 turns) the screw 5
This is the way I chose, and it was easier, I think...
OK, I see !
Maybe you broke it because it was fragile ?...
I saw on forums that many people had to change it.
And that was the same for me !
I changed this piece (079133424S) 1 week before, because it was broken just after the coolant line...
If some of you want to remove the manifold and if your car is more than 6y old or more than 60,000 miles, I suggest you to change this item...
