K-Jetters, check your O rings!

Fitted a set of injector O rings to the car today, couldn`t believe what I found.

The top big donuts were loose, and these had been letting water in over a period of years probably, pulled the injectors and there was loads of rust, looked like I was pulling corks out .

Seriously you need to check them, I`m looking out for a set of injectors now, they`re that bad! Wish I took the camera with me, you wouldn`t believe the state they were in!

 

Get Merc 190 injectors - they are cheaper, brass instead of steel, and are said to give a slight increase in performance.....

 

Sounds promising!

Cheers, will have a look.

 

going to pull my injectors this weekend when I whip the head off.

can someone let me know the part numbers off etka?
(two sealing rings per injector right?)

cheers

 

Part number for the Merc injectors is 0-437-502-047 apparently, from a 1986 2.3l 190E. From the Vortex....

 

sorry mate

meant part numbers for the injector o-rings

hoping I don't have to fork out for new injectors...

 

I got some new o rings last week from gsf, changed them over but the old ones wern't too bad. But it was worth changing them for piece of mind and they don't cost much anyway.

 

The numbers for those were posted on here in the last fortnight or so - my Etka isn't working at the minute or I'd find them now. But if you try a search they should come up.....

 

Are the O rings replaceable then. Just had my injectors out and they were brittle and loose. thought they were a fixed part of the injector. duh

 

Yup, and yours need replaced by the sound of it - causes vacuum leaks.

 

Ones I got were the green viton? ones, will dig the numbers out. 15 for 8 though from vag!

 

034 133 557e (top oring big donut!)
035 133 557a (bottom o ring, mine didnt seem too bad)

 

Anyone know which model came equipped with injectors # 0 437 502 045?

Thanks

 

They are from a Volkswagen, look here on page 27.

 

I want to change mine om my mk1 as they prob been in the car for 21 years hehe. Can I upgrade the injectors on a mk1 gti with anything else?

Cheers

 

How do you get the injectors out of a MK1. Tried to pull mine out but they wouldn't move.

Do they come on their own or with the braided pipes attached?

 

The injectors come out with the braided pipe attatched, If the injectors are not coming out you need to pull harder. On mine i used some mole grips and a bit of leverage and the injectors came out no problem.

 

Keith, will you be replacing the injector pipes aswell? Mine have surface corrosion on them.

 

Are the braided pipes part of the injecter or are they sold as seperate items?

 

They come complete as far as i know,
