did all your injector tube's come out when you pulled out the injector? or if they didn't come out did you just leave them in and not worry about it?. GM has a tool for pulling the injectors and the injector cups did you need that?

 

if they didnt come out just leave them there. its a real pain to clean the mating surface of the head where the injector sleeves meet up. the one i pulled out came out because the injector got stuck to it and did not want to let go.

 

Did you use any sealant under the lower valve cover?

You mentioned you did under the upper...but nothing about teh lower.

Excellant write up and pics



.

 

the lower valve cover uses a rubber seal to seal it up. They are sometimes reusable, depends on how they look. i have had no problems using the same rubber seal 3 times when doing my injectors, the only hard part is getting it to stay on the lower valve cover. I used vasoline and make the rubber seal stick to the lower vc so i can install it.

 

Sweet write up Danny, that helps a lot! Looks a lot less intimidating than I thought.

 

If I drain the coolant out my radiator will that stop coolant from going into my cylinder?
What would I do if I did get coolant in my cylinder?

 

if you get coolant in the cylinder bump the engine over with the starter go get the coolant out. make sure to cover up the hole with lots of rags.

most of the time yes draining the rad helps

 

exellant thread danno i am going to be doing my new dmax soon with larger injs now i dlont have anything to worry about it seams simple

 

if its a new dmax u it should take a few hours to swap injectors, no need to pull the valve covers
