I had to use a straight test pressure gauge since the kit I borrowed from a friend only went to 300 psi. I called all the parts stores in town, but none have a tester for these high pressures.

I had all the UVCH's laying on the bench and disconnected the huge engine harness connector to get it out of the way, so the #7 injector should not have been spraying fuel, especially that much.

The rockers look good. No obvioulsy bent push rods either but I didn't remove them. It may be a good idea since I will be waiting for injectors anyway. How do you remove and re-install them correctly.

I will take a look at the anti-freeze and report what I find.

 

There is a write up in the stickies on injector install.

 

I meant the push rods.

 

Just unbolt the rocker assembly and take them out, its pretty straight forward.

What about re-installing? Whats the torque spec?

 

I took a sample of the antifreeze through the drain **** in the radiator. Below is a picture. It looks kinda brown. I couldn't find a compression tester gauge that shows maximum PSI that is rated for 400 psi so I worked on my simple gauge and had my father in law watch it as I cranked the motor over.

The numbers were consistent between cylinders today, but still low. I decided that since they were all giving about the same results that I didn't really need accurate numbers at this time. So I moved on.

I pulled the injectors and found that my past dumba$$ mistake has caught up to me. The second picture is how about half the injectors looked when I pulled them out. A year and a half ago I put new external rings on and didn't have a small enough torque wrench so I guessed at it. BIG MISTAKE. The hold down bolts on some of them had worked loose.

#7 seven luckily did not have a busted off tip! Who-hoo! But the lower most o-ring was almost cut in half and the lower portion of the injector looked about like the one in the picture.





Could the torn ring have been the problem or it is still an internal problem in the injector? Either way I will be sending them to Rosewood. As far as I know they are original injectors just shy of 280k miles.

 

That injector is pretty dirty on the end, it looks like it was leaking combustion gasses past the copper washer on the bottom.

A cut o-ring could cause the problems you had but I would think it would set a CEL in the process.

There was no CEL when it happened but it working because it came on when i turned over the engine without having the harness plugged in.

 

I got my rebuilt/upgraded stage I's from Rosewood on Friday, a new intake boot and SD VC gaskets and harnesses from Riffraff. I also did the "Perlich mod" (atleast that what my friend calls it since I'm probably the only one to ever do it, but thats a different story.)

I got 'ol Great White started up Sunday evening, and then finished buttoning everything up Monday afternoon in the stinking rain. She is running like a Champ now. I cannot believe how smooth it pulls through the rpms. It used to be pretty shaky in the 1000-1500 rpm range. Also it feel like it actually has some power now, but the roads have been wet so evertime I push it a little I just spin the wheels (which is more than I could say before).

Thanks to everyone, including Jim and Clay, for all the help. Now I just need a chip!!

 

I need, need and want! LOL Glad you got her going.
