Yeah, all the return lines were probably original and i replaced them all already. I did get it running, but it still doesn't appear air tight. I'll mess around with the collars and o-rings again later. The important thing is it runs.

it lives. After replacing all the return lines and fixing a couples loose fittings i got it bled and 1 cycle of the glows and vrrooom. The old lines were almost like plastic they were so hard. Go to say i don't like the injector return fittings. the collars with the o-rings are a pain...

haha! i do actually. Can anyone point me to the the DB2 to DS4 conversion thread for a 7.3idi? :rof:

hmm. well fuel lines are off right now, but after i get it back together tomorrow ill try it again if need be.

i tried. but apparently they changed the formula so it wont work for that anymore? at least thats what i read. and it seems to be true. not even a cough. just eating then im going to go out and see take a look before it gets to dark and cold.

glows are about a year old bosch duratherms. i'll probably pull them and check them too. seemed normal though.. It didnt even cough or try to fire at all though. just smooth cranking with white smoke out the tailpipe. its 3C and sunny out right now. i would think it would at least try to fire...

I thought so. Could be air in the lines i suppose but even when i've run out of fuel i've never had this much problem with air in the system. I'm going to have it towed home tonight and I will see about changing all the return lines an o-rings (i have them sitting around already). Could it...

ip is cold. it was parked at 8:30 and i tried to start it at 1:40. i say this cause thats a trick for a dying ip with hot start issues right?

So i just about an hour ago i went out to get a late lunch at the truck wouldnt start. cranked over just fine, wait to start light came on for the normal time ( i could hear the relay click as well), white smoke out the tail pipe. i have fuel, and there was no air restriction. It started up...

so i drained all the oil and tore then engine down to the heads this weekend. valve covers and the cdr have nasty goo in them. Heads seem fairly clean, but there was some gunk. The oil i drained looked normal. pressure tested the coolant system and found this...

That is basically what i did. Didnt use arp stuff, and i did the studs a bit more than finger tight (used an allan key to tighten them up a bit, but nothing considerable). basically followed the arp instructions.

I am going to tow it up to my dads this weekend. its an 1-1/2 hour drive and i dont want to cause anymore damage. im not going to drive it this week either. Done it once before too, gotta say im rather impressed with the 7.3 IDI. This time it will be towed with either my dad's Cherokee 3.0L...

Well the truck is off the road and going up to my dads shop again next weekend. But it's too late for the turbo. bearings are shot. Dont know if the feed line got plugged or if it was coolant in the oil. Gonna replace the water pump on the ford and the chev will sit for few weeks till i can...

oooh i see. the first time i looked at that pic it looked like you had grooved the inside of the bolt hole. you just put two steps into the top for the o ring, and then i assume you clamp the o ring in place with the washer. I was wondering about doing that with a chamfering bit. I suppose...

that is an excellent idea. i wish i had the equipment to do it. Also i like the color you chose. :thumbsup:

Yeah your right. almost there at that point. 1 stud would be nice. It doesnt leak that quick and im not seeing an increase in oil level. I'll try throwing some coolant tabs in this weekend watch my coolant level closely. If that doesnt solve the problem I suppose ill be tearing it down one...

Hmm, didnt know about that stuff. I used moly lube like ARP's instructions suggested. seemed to work fine.

i didn't go as far as you but i did tighten mine as well. i used an alan key and tightened them up a bit. I'd rather not pull the heads again so soon after putting the whole thing back together, thats why i was wondering about doing them 1 at a time. i was thinking taking them out 1 at a time...

So, i just redid the heads and cam in the truck, as well as a blown head gasket and i've been losing coolant. I found a couple leaks at the heater hose quick disconnect and the t for the rear heat. Fixed those, although i'm not too confident with the fitting. But that's another issue. I...

I tried to get a set for my rebuild and the supplier ended up coming back to me saying that the mahle 18:1 pistons were discontinued. I later talked to mahle, and it turns out the supplier had misunderstood. the 18:1 pistons weren't discontinued, just the .040 over ones i ordered. i dont know if...
