    Looking at upgrading injectors on my 04 BEW Jetta. I replaced the cam last year and that was... a job. I see the injectors are under the valve cover, but I don't remember quite how they were fastened in.

    Can I do this by simply removing the valve cover? Need I be at TDC? Anything beyond pulling the injector rockers off and lifting the injectors out?

    new bolts for the rockers to as tty...

    the injector has a bolt at the base of it... gotta drain cooling system... i beleive there is coolent flow around the injectors and will make you a nice mess.. now the trick is the tool to get the injector out of the head... i watched a guy jumping up and down on a 10 ft cheater bar bend a injector body... he refused to wait for me to grab my "lady finger" a 12" prybar that the end is 90* to the shaft and flat like a screwdriver.. i slipped it into the gap by the bolt anchor spot.. gave it a twist like loosening a screw with the tip.. pop out 3 were in 45 sec.. the bent one took me a hour as bent in such a way it had interfearance fitment issues now.. my pool would have never allowed it to get bent

    Ok, so the gist of it is, drain coolant, remove valve cover, undo bolt at base of injector, pry out with fine tool (thank you for links!!!); then installation is reverse of removal?

    pretty much... new o rings and such for the injectors.. lotsa lube on new ones when installing.. to damage a o-ring will fill coolent, or oil.. or both with diesel.. i do the twist while pressing into place as to not nick the o-rings.. not alot of room to twist..

    Forgot to check - do I need to drain oil too?
