Cylinder head injectors

[jbturgeon]

Hi guys, i would like to have some advice as i am installing a cylinder head for the first time.
I was wondering if there was a pattern to follow for the soft rubber lines between the injectors?

I was also wondering if it matters if there is a 1 mm gap between the flywheel mark (tdc) and the arrow? (i guess it does!)

Last question: Do i need to bleed the injectors lines? Before or after the timing belt installation?

Thank you very much again!

Have a good day

a 1mm gap isn't too much, but it will affect the timing slightly.  you need to make sure you're looking straight down at the arrow, as the angle will distort the proper position.  you could make your own mark for TDC, or just make note that you need to position the flywheel 1mm over.

bleeding the injector lines isn't really necessary, but helps diagnosing fuel related problems, and its always nice to see fuel coming out of the lines.   the rubber return lines don't necessarily need to be in any order to work, as long as excess diesel can flow back to the pump, and then back to the tank.  you need a plug on one injector, and a return to the pump on another.  the rest of the injectors connect to eachother.  the plug is normally on injector no.1, and the return on no.4

Thx JTanguay! I am actually turning the ip sproket and there is some diesel coming out of the pump but nothing at the end of the line. I am a bit curious about it. I have been really clean in removal.

Any issue?

SORRY, no gazoil coming out of the pump! There was a spray two days ago. Can it be because i have rotate it counterclockwise?

thx

you'd need to spin the pump very fast to get it to push diesel out of the lines.  it needs to develop enough pressure on the inside, and can take a few hundred rpm.

i'm not sure about the rotation of the pump, but you don't really need to worry about that.  just install the pump on the car and the starter will spin it fast enough  :wink:

thx guys, my pump is sparying since i put the negative back and turn the key on.. Never thought it was that much electric..

I have align everything and will try to fire her up really soon.

When setting up the timing belt, loosen the cam to pulley bolt and "break" the pulley to cam "connection"(press fit, for lack of a better term).  Meaning, use a puller to pull the pulley off the cam just enough that the pulley will rotate freely on the cam. The cam should be locked down and the cam pulley should be loose and able to rotate on the cam. This will allow the TDC mark to be moved to exact TDC.  

Dont forget to tighten that cam pulley after you have tightened the tensioner.  And always rotate engine by hand 2 revolutions to make sure there is no piston to valve contact.
