So, the previous owner installed the new injectors with teflon tape on the threads?????

It looks that way. He said that he removed the injectors to clean them, and after reinstalled them, it wouldn't start.

The Motorcraft glowpugs should be Berus, just twice as expensive from Ford. Do you have an Autozone nearby? They have carried Berus. Be sure you get the proper part number. It should be like "ZD9" which happen to be 7.3 plugs. A parts house for big rigs that can get International parts should be able to get Berus. All the same plugs whether Motorcraft or International. Take one of the old ones in to match them up in case the counter guy is a dweeb.

Thanks. Looks like the Motorcraft part number for 6.9 glow plugs is ZD1A. I've read on here that some Motorcraft plugs are not made by Beru, though. Also read that Autozone discontinued carrying them.

Tonight I cleaned up injectors 1 and 2 (removed the teflon tape), and tried to clean out the injector bores. I can't seem to get the **** out of the bottom, where the copper washers are supposed to seat. Is there some sort of tool, like a stone or wire brush made for doing this?

EDIT: I think I found the answer here: http://www.oilburners.net/forums/showthread.php?t=10319

Just not sure if the injector seat reamer is supposed to be used with the heads installed or not.

Wow, that is close. Probably 10-15 minutes away from me. Yeah, I'd like to get together and see your truck. I looked through your pics, looks like you've done a lot of good work on it. Curious especially to see what you've done as far as underhood wiring, and also check out the front end conversion.

Ryan I drove 5 hours to find out that liddledoggie lives bout 35 miles from me.

 

[tbiagent69]

Make sure you guys keep this thread alive, I am really interested in seeing what the problem is!

Snuck on the computer over at my parents house to give an update.

Well I can shed some more light on Alans problems on the no start on the truck..
He shipped me the injectors yesterday and wow. Paperweights they are.

3 wouldn't even pop open at 5000 psi
3 popped at 1200 psi then bled down to full blown leakers.
1 popped off at 1500 psi with a fair spray pattern.
YUK!

1 got left on a battery in OH,but I think that will make a nice paperweight also.

Hopefully witha fresh set of injectors, we can hear this thing light off.

Ron, thanks for doing that test. Even though it sux to have to buy new injectors now, it's good to know for sure that they were at least part of the problem. I'm sure the low compression was part of the problem, too. Hopefully those numbers will go up considerably after I use the injector seat reamer that "icanfixall" is sending me to borrow.

Oh, and this is for holstein... pm sent.

Funny how it never occurred to that "pm sent" is a pretty stupid thing to post. But it's done all the time in another forum that I'm on regularly.

make sure there's no copper washer still stuck in there. before you use the reamer.
