Question Injector Install - Unique/Different Method

I'm almost ready to install my stage 1 Injectors and I remember reading somewhere that if you swap your injectors fast enough (say pull out your old one, and stick in the replacement injector imeadiately,.... one at a time) you could do so with out draining the rails & HPOP resivoir. And no chance of Hydro-Locking using this method.

Anyone have any knowledge of this?

Seems like I read this in Diesel Power Magazine a few months ago (while standing in line at the local Wal-Mart) where they had sort of a build-off challenge between two OBS trucks. One was a gasser w/ 351 that they put heads, intake & etc on,......while the other one was a Powerstroke that they did the typical air intake, exhaust, chip and of course (Beans stg 1's) injectors and sent both of them to the dyno.

I'm just a little leary of some of the things I read in the mags at times.


Of course my injectors are still in the truck and my Stage 1's should be here tomorrow.

I agree don't think you'll be able to do them fast enough to not at least have to pull the glow plugs and turn it over a few times

It is not hard or real time consuming to pull the fuel plug on the back of the head and the 2 oil rail plugs under the valve covers. If you pull the plugs after you remove the covers and than go pull the other cover and plugs their should be very little left to get into cylinder.

The oil plugs are little 1/8 plugs that are under the valve covers, at the top of the cylinder head and its doesnt drain the oil gallery until one of the injector is pulled. The Article was Diesel Power Dec 08. It should work just fine, but it doesnt allow you to inspect the injector bores and clean them out.

Regardless of how you replace them, pull the glow plugs and purge the cylinders, or you will blow something. Also I would suggest if you are going to clean the injector bores with a solvent. DISCONNECT THE GPR!!!!! I turned the key on the first time and about SH!T myself when it lit off and back fired!!!!

yeah I would be weary of that method, if you really dont want to you dont have to take out the oil galley plugs or drain the reservoir, but when you purge the cylinders a whole lot more oil is gonna come out of the those holes at a high velocity and starting will be a little more difficult

I'm in total agreence with all these guys, i wouldnt do that. Though i didn't pull my plugs. I just pull'd the glow plugs and truned the motor over a couple of extra time. You might want to keep a battery charger handy. Cuz after the injectors are installed It took a good 15 min's of cranking and waiting and cranking again before she started

Exclamation

Well,.....

What do you know,...... I tried installing them this way and guess what happened ....???


































It Worked



Started on the second try. It stumbled a little at first, but smoothed out in a few seconds.

It's ironic that I mentioned doing this and it just so happens that the guy that did my Injectors does his own swaps the same way.
how to do injectors..

Well, there are ways to do it that work, and there are ways to do it to be thorough and cautious. These guys offer good, sound ,cautious advice so as to limit any possible problems later.
Of course it's best to suck/pump/purge all the oil/fuel from the cylinders.

But...
If you're quick enough hardly any liquid gets into the chambers and usually isn't a big deal.

Glad it worked for ya.
