No.. I would put the plug in.. If you have air in the cylinder, it could get pretty messy...

 

LOL,, that would be my luck

Hey on a unrelated note,,, why do you think I cant get the tube out on the #6 injector,,, it just wont come out no matter what I try

 

Kevin, does the engine hoist cylinder have a **** integrated with a lever as the release valve?

My Princess Auto imported hoist that has a **** & a lever integrated together
to be some kind of mickey mouse "quick lift" feature or super slow lowering feature.

It drives us nuts & I can never remember which one to loosen or tighten when pumping up or releasing the pressure.
I think that you should never have both tightened up at the same time. If you get it wrong it has no lifting power.


...Joe

 

Not that i remember seeing Joe, just the normal way of lifting and lowering,, but there is 2 recessed screws on the base that say not to touch

 

What the problem? You cant get it to pop loose? Or you dont have enough room to get it out of the head?

 

I cant get it to pop loose... Im not even worried about getting it out of the head,, if I could just get it to come far enough out so I could pull the injector Iwould be happy

 

Well, theres you problem - youve got to tinker with them a bit...

I was kidding about the instructions - a real man throws them out when he opens the box...

 

Must be really stuck I was able to just pop them all out by hand. Have you tried it with the injector bolts loose? If you have the rail off maybe try threading the nut back on a ways so you can get a flat blade screw driver behind the nut to pry on it a bit.

 

i have the bolts completely out on the injector, just like on the others.. I havent tried the nut, but I did try a set of visegrips and a screwdriver... I think maybe I will try to put the bolts back in on the injector and see if that helps out some

Its always #6 that's the tough one. If you have no other choice you might try finding a washer that just fits over the connector tube then threading the nut back on and tightening it down on the washer creating a puller. Might wreck the nut doing that though. Or try and find a regular nut to use. Although it really shouldnt be that tight, unless something else is going on??

I don't know if you plan on putting new connector tubes in but its a good idea. On my brothers truck ever since putting in injectors in he had rail pressure issues and eventually had to put new connector tubes in. Also follow the steps for installing the injectors closely and save your self hassle later on.

Good luck and look forward to finally meeting you and seeing the beast up close this year.

 

Kevin...To bad your so far away..I would let you borrow my bottle jack from my engine hoist...I think some sort of seals must blow out just like my 6 ton floor jack.Can't beleive that lefting my truck in the front blew the jack out.Its not like 6500 lbs of truck is all in the front end.I had another floor jack that did the same thing.Put more oil in it and removed all air in the cylinder...Landed up in Calgary metal in the end.

 

I must of been up to late, I was thinking the connector tube nut threads onto the connector tube but it just slides over it and threads into the head. So that wouldn't work but just a regular nut might. Although vise grips and a screwdriver should be more then enough to pop it out. I would also tighten the injector back down so know everything is aligned. I wouldn't be to worried about wrecking JUST the connector tube there only $30 bucks and its recommended to change them.

If your pulling the head by yourself it will be really hard not to damage that injector if you leave it in especially with it being #6.

 

Thats exactly what I am thinking.. I was thinking about trying to do it with the injector in, but as I wa surveying the situation, it looked like that chances of something going wrong were close to the 90% mark

And yes I am totally prepared to replacing the tube, there was another allready that I had planned on changing out too... must have been # 6 the last time the injectors got changed

 

I had one injector stuck in the head. The darn copper washer let engine combustion up into the injector and caused lots of carboning. Just lift the rear of the head first so you don't damage the nozzle tip. I built a injector puller and just slowly popped out the injector. It was stuck in good. You should be able to wiggle head loose by hand. If you can't something is still attached and holding firm.

Dumb question, how many studs have you removed? Have you removed the rocker arms and the rocker pedestal. Push rods? The head isn't too heavy and should be easily lifted by any typical engine hoist. The rest of the engine is different,as it weights more than a typical 350 chebby. I usually leave in the connector tubes and injectors. This will preserve the seal on the tubes and injectors, but saying that you have to be extra careful, not to damage those nozzles on the bottom. Good luck, I tend to ramble on lots...

 

LOL, thats ok Mike... I dont think that the injector itself is seized, its that darn tube that just wont come out... the other ones were easy.

As for the head, I can lift it by hand, but that beautiful crane that I have wont,, lol
