Serious problems...

Yes they had the tab but when I lifted the head off two were loose. They fit in the bore and the tab lined them up but they could fall out. I mean the head is on the motor now so they can fall out but I hope that wasn't the problem.
 
So what does this mean the head is bad ?? I blew air into them while the head was off to clean out any crap that might get in while I was cleaning and I think that loosened them up. I put them right back in but they barely stayed in while I was putting the head back on. They were not a "press" fit. Should I stop ? Both heads are back on. The only other thing that was weird was the two bolts that go in where the dowels are seems like they should have been a little longer.
 
They can't fall out with the head bolted on and they are not Loose but not press fit either. Do they just go straight in or should I have turned them to lock them or something ??
 
If they are not press fit will the compression burn out the fire rings ? Shit I just put this whole thing back together. Maybe that's why the HG falied ?? Why does this stuff happen to me. I should have just cut it up.

Already torqued the headbolts?

If not we can pull the head off tomorrow and take a look. If so then i dunno what the next step would be.

The CCLB heads i removed the precups all looked to be in there quiet tight, but i didn't try to remove one either so i can't really tell how tight they are in there.

The engines at school the precups seemed to be a press fit. I tried to remove one there but gave up since i didn't have the right tool to begin with. Not sure if those were frozen in due to rust(piston seized in bore from water) or if the precups really are that tight.
 
My guess is if they were tight when you removed the heads, the compression of torquing the heads down will tighten them up again.
 
I don't know. This is only the second time I have done heads and I don't remember having this problem. The heads are torqued so 300$ worth of gaskets are junk if the heads have a problem. I will not remove them again. If it doesn't run the truck is getting cut up for parts or possibly I'll look for a used motor. That is what I should have done. I knew this couldn't be simple. It never is for me.:mad:
I don't know what the hell is going on latley but it's like someone pulled the plug and everything I touch is going down the crapper. I'm ready to junk everything and buy a Hyundai. Maybe the Jimmy will run good. I doubt it. There will be someone more serious with that too. I will guarantee it. I;'m a walking jinx and I think maybe the only thing left to do is junk everything and buy a brand new something with an extended warranty. I thought i was buying something decent when I bought the Dodge and I got screwed and lost 5k$. I can't keep this up.

You start junking shit you wait til i get my pickup running. ):h My blazer could use a spare engine with all the shit that's gone wrong with it.

For shits and giggles do you want me to bring my comp tester with the 6.2/6.5 glowplug adapter tomorrow? We can do a comp check on the jimmy before even starting the IP job. If the comps bad, no sense wasting a good Ip and injectors not to mention time you really can't afford to waste since you've got the oil trucks to worry about as well.

That tester is the way i found the intake valve that's too long and the lack of a valve job on cylinder 2 on the CCLB.

I"m sure out of all these trucks you can make one good one, even if you pull the engine from the jimmy and stuff it in the burb for example.

Agreed. The clamping force from all 17 headbolts is huge. Also consider the precups really have no where to go once the head is on. As long as the precups were flush with the head surface i'd say your ok.
 
They were perfectly flush with the head. They weren't sticking out out at all. How could this be ? What does it mean ? Is it leaking compression around the precups and burning the firerings out ?? The fire rings on the old HGs looked ok.
 
Yeah I could not believe how tight those bolts are. I am pretty strong and I was feeling it tightening 34 of them. The thing is too that the worse looking HG came from Passenger side and the loose precups are on the drivers side.
 
Hey has anybody had trouble getting the right Donuts for the exhaust ? Both NAPA and Advanced gave me the wrong ones. They say on the bag that they are for a 6.2/6.5 but they are too small.

A buddy over on DP said he had Loose precups in one of his rebuilds and it meant nothing...That made me very happy to hear that.

You've told me this before and now i'm giving your advice back.

"You know what you have to do" We'll get it all back together tomorrow and fire it up. That's the only way to tell at this point.

Same goes for the Jimmy. My blazer sat 10 years and the comp was sort of all over ranging from 350 to 410 but with a new IP is runs great save for that bad lifter. It was a gamble, but anything that old will be a gamble. I"ll bet if we check the comp it'll be ok. How's it start even with a dying IP?
 
The Jimmy actually starts pretty good. Just smokes alot. I know the IP is screwed. The advance is stuck and does nothing when I move it with a screwdriver. I bumped the IP too and it made no difference at all. It's junk.

We'll start there then. being an 83 is there a chance it has the coarse thread red block injectors or are they the fine thread injectors?

The advance worked on mine, but the pump couldn't build enough pressure from the water damage it seemed.

My blazer started great even with a bad IP and at least two dead glowplugs.
 
Gotta fix the CUCV as well. I have no wheels right now. front brakes went on it and it has a charging system issue I have to shoot over to Steel Soldiers and do somehomework.
