1086 injectors

how is the best way to take out injectors in a 414 engine. i have heard that they can be very hard to get out. jim7

First off, drain the coolant as the injection nozzles fit in a brass sleeve which is directly exposed to the coolant so if sleeve loosens you may end up with cyl full of coolant. Second, don't twist back and forth as this will only make them bind tighter. They should actually just pull out easily if top dirt seal and lower compression seal are good. Usually just a small rolling head bar will pop a tight one out but you may have to devise a puller. Before installing them clean sleeve good including the hole in bottom where tip extend into comb chamber and try fitting injector into sleeve with out the top seal to make sure it drops right into bottom on it's own weight. I have seen them where they leak combustion after installation due to the carbon build up in that hole and injector not bottoming out really easy. Torque clamping cap screw to only 12 ft lbs .

The simple answer is with an injector puller designed for that engine. I would not expect you to by a puller for just your own use. The main advantage of the puller is that it will pull out the stuck injectors, usually along with the sleeve.

The first thing to do is drain the cooling system, at least to a level below the cylinder head. If you have an injector seized to the sleeve there is good possibility that the sleeve will come out with the injector. If you do not drain the coolant before you start you run the risk of getting antifreeze in the cylinders.

If the upper seals are doing their job the injectors will come out quite easily. If moisture has gotten below the sleeve there is a good chance that the injector will be corroded to the sleeve. After removing the retaining bolt try twisting the injector to break it free. If you can get them to turn they will usually come out fairly easily. If they are really stuck you can use the hold down bar on the injector and use a pry bar on each side to pry it up. If an injector sleeve moves it needs to be replaced. If you just reseat a sleeve you run the risk of it leaking after you install the injector.

I like to coat the outside of the injector with grease when I install them. That usually insures that they will come out easily the next time they need service.

owen aaland and pete23, thank you for the advice. i was able to get the injector out.
