Tips for seating injector for # 5&6 cylinders

Posted

So feeling like a bit of an idiot for trying this project during a very cold weekend which is contributing to my install. Not my first time upgrading injectors.  However, can’t get 5&6 injectors to seat. Can’t apply enough pressure to push down on them and as they near the back can’t swing a mallet either. it’s just about freezing so fighting the cold metal and moisture in the air which is making it doubly hard. Anyone have any experience or tips to seat these? Can I use the hold down rocker arms and and torque the hold down bolts to seat them? Dumb of me to try this in the cold but hey.

i've use the hold down to leverage down the injector  should be fine.

Thanks. Yeah really no other way currently that I can see to do it.

Just double check for something dumb before doing it, but I am guessing a little bit of force and it will pop right in.

1- 4 cylinders needed a few blows of a rubber mallet to seat them. Has to be the cold because I couldn't apply enough downward force to seat and I’m not a small guy. Why I didn’t do this a few months ago when it was 70 degrees out is beyond me! 

Only thing I have is I had a crossover tube slide down on me and I fought that for 20 min. before I figured it out.

I wonder if you put the injectors in the house for an hour or two and let them come up to room temp. I'm guessing the big O ring is not wanting to compress as needed to seat down in the socket in the head.

I finally got them installed. Crowbar against the rear firewall worked wonders! Everything’s buttoned and tomorrow I’ll start the bleed process. Should be fun.  Hope my batteries hold out!
