I have to agree. I've seen hose's go.. many ways, but never like that!

"Almost looks like sabotage......."

His wife doesn't know the difference between a radiator hose and a brake line.

Did she act surprised when she saw you come home....in one piece? LOL!

Never ever! The edges are too clean to be a rupture, except for the very end. Did you leave it unattended at any time?

 

[jdxj]

No I was driving when It blew!

And My wife was with so She didn't do it!!!

It was a cheap Vato zone hose. only about 6 mnths old! A buddy of mine (a pro mech) said he's seen em do that with a bad Head gasket. Witch I'm guessing is my problem. Been having Overheating issues even with all the cooling system components upgraded and replaced. Plus a huge loss of power in the last week or two. So Ima have to check that out.

 

[NW-ZJ-SCOTT]

Bad headgasket could add pressure to the cooling system.. It does slightly make since

 

[loren mcclellan]

yeah loks to me like someone helped that along... I ain't never seen one go like that!

 

[YELLAHEEP]

The pressure it took to blow that hose like that would have me VERY concerned about the condition of the radiator as well. They aren't supposed to withstand that kinda pressure.

I think you're on the right track JD - with all the overheating issues you've had, it's gotta be a bad head or head gasket.

 

[jdxj]

Ya Ima probley just replace the head if I can find one! Radiator seems to be fine it's almost brandnew and also is a all metal unit 3 row. I think it had to ba a bad hose though because the rad cap should release at 16psi and it's a brandnew rad cap. SO im cornfussed again but the head and head gasket is the only thing in the entire cooling system thats not new so thats gota be it right? LMAO if that don't fix it I'll just pull a infor anotherjeepeverytimeichangemyunderware and sell the darm thing!

 

[old_man]

I would just replace the hose and see what happens. No reason to replace a head without confirming a problem. After replacing the hose, run it a while with a new radiator cap. If it doesn't puke all over the place, I might have a mechanic use a sniffer to sample gases from the radiator for exhaust gasses.

I'm betting it was just a crappy hose.

Ya I'm pretty sure it's the head or Head gasket cause now I'm geting the whiteish gunk in the oil. IMA take it to a buddies shop tomorrow and have em sniff it out but I'm 99% sure thats the problem! And I think your right the hose was shit! Thank you Vato zone. It should have at least held the 16 lbs to let the new cap relieve the presure.

Pull the thermostat and check it in boiling water. I had a new quit opening after overheating a couple of times.

DONE works fine!

So bringing this back from the dead...just purchased this motor and have stripped the head off, but still haven't found any evidence of what was causing the problem.

So i'll throw up a bunch of photos

Bottom of head:

Top of head, head gasket on top:

Top of head, bottom of head gasket:

Now onto the head in between the rockers. This is the infamous 0331 head, but after looking it over I'm not seeing any cracks anywhere, not even between the 3rd and fourth cylinders.

Between 3rd and 4th:

Rest:

So needless to say i'm a little perplexed...

-Didn't see anything that indicated a blown head gasket from looking at the gasket
-No fluid (or evidence of) in cylinders as far as I can see
-No cracks that *I* can find on the head

So the only thing I can think of is that the head might be warped enough to have caused the issues? I'm going to get it cleaned up then take it and run a dial indicator across it on an end mill to make sure its within spec of runout.

Any other ideas?

 

[xj-grin]

I was reading your post thinking there was going to be a "gotcha" at the end... I didn't see anything either. Gasket shows now fluid penetration, and from your pics I don't see any cracks either (my bad head was a casting defect with cracks behind no. 6, FWIW)... warping would be all I"ve got, but man that is some seriously nasty AF/Oil gook in the passeges.

He's talking about the coolant passages. Is there a film of oil or grunge in the cooling system, residue on the radiator cap seal?

Take the spark plugs out, clean the combustion chambers with a cup brush. Be careful to not wire brush the valve seats. Check the area between the valve seats for hairline cracks. It doesn't take much of a crack to start pumping coolant into the cylinder, or compression into the cooling system.

 

[xj-grin]

I was, but now that I am at a better monitor, the water jacket passages look crusty, but not oily...
