possiable sieze!!!! help me and give advice

i have a 1974 jeep cj5 with a amc 304 v8. I recently changed my oil filer in an oil change and i guess the filter was leaking. I was driving down the road to my buddies place and i started to see smoke which i just assumed was a little bit of runoff that dropped on my headers then about 10 yds down the road i hear a squeaking (not like the sound of bad belts like the sound of metal on metal). I did not want to stop and check it out because I was literally 30 yds from my buddies house. until i was about 10 yds from his house and i was at a light and my engine quit and would not completely turn over. once we rolled to my buddies house we tried to crank it again but it sounded kinda half way. O and my oil pressure was 0!!!(but i on the bright side i did get a half way crank). so we threw about 2 quarts of oil in it (all i had on me) and began to figure out where the leak is.

Has anyone had anything similar happen and know what the condition of my engine might be?

Yeah you just screwed the pooch. Sounds like either the filter was not tight or the old gasket was left in place when the new filter was installed. There are only two situations where you continue running an engine when you have no oil pressure. When taking on gun fire from an enemy and you need to get the ^%$^ out of there, or when lives are inside a burning building and you are the engineer of the attack pumper at a structure fire.

Thats a sad story Pete, but look at the bright side, heres the oportunity to drop a simple little straight six in there...
poor little Jeep

Here's an oportunity to get after some torque and ponies. Rip 'er down and build er up!!

Sounds like a rebuild. Too bad you ran it till it stopped, more damage.
You could also consider a long block exchange. More $ but less down time. Best of luck!

ok so today i pulled out the oil pan and it looks like it was comming out the front end of that. so i pulled it out and from the bottom everything looked like in good-ish shape except for two piston rods(i think that's what you call them) and some parts in that same area on the cam shaft, they were all burnt black. but i stuck my finger up there and the piston head felt slick so i think that's good. i also almost got it to turn over until my battery decided to die...ug! i just hope its really my battery and not a stuck piston.

 

[Raimond]

Pull the end caps from the piston rods and see how the Crankshaft looks. Or is this what you mean by 2 connecting rods look bad? Did the bearings stay on the end cap of the rod or did it stay stuck to the crankshaft?
Pull the intake and see it the camshaft is burnt as well.
Turning it over anymore at this point will only cause more damage as there is no oil in the metal to metal contact areas.
It is uncommon for a front seal to completely fail all at once letting that much oil out of the pan. Wind swirling will sometime blow oil forward and cause you to suspect a leak where there is not one.
Another line of thought is that the damage is done so go for it and try to get it too spin over.
Keep us updated.

sry it would be easier to explain if i had a pic, but i don't. so let me try to explain better. the parts that look bad are, when you have the oil pan off and your looking up at the bottom of the engine. that part that is usually a brass or gold color with 2 screws in it and then the rods going up to the piston head, they are black i don't think they were wielded together or anything but i know it did get really really hot and it is prob just burnt like hell from the oil probably burning up. do you know what im talking about now?
the other 4 sets of pistons are fine tho, and when my engine quit, i immediately threw some oil in the engine. also when i was trying to turn it over today, it was after we re-sealed the oil pan and filled it w/ 4qts of oil. so it was not metal on metal at that time.

btw, just thinking out loud, would it be possiable to make it a v-6 and just get rid of that section or do i really need that combustion there to move the camshaft. i probably do don't i?

you need all of the cylinders working in order for the motor to work right. i would find a AMC motor and put in there.

 

[Saddle Tramp]

I would look for a used AMC 360 from a junk yard that has good compression. They should be plentiful. It will be a direct bolt in with no mods, even the existing clutch will work, except you will need to make sure you have an AMC 360 flywheel. AMC motors are externally balanced and each motor has its own flywheel. Still, cheapest way to get you back on the road.

ya, i have thought about that but that's worst case scenario tho.

 

[sweetpeet]

what would it mean for me if my valves were burnt?

 

[Shewilly]

But doesnt your current situation classify as worst case?
Why not look into a motor that is beginner friendly?
Ask Santa for a Chiltons

i have one bud. and i dont need a motor that is beginner friendly, i just need to pay more attention to my ****!

 

[John B]

what might of happened is the whole motor is shot. the motor may never be right without putting alot of money into it. like new heads,shave the block all new valves camshaft crank rods pistons

The color of the internal parts does not matter. Older engines that ran on oils of yesterday often have burned deposits and black coatings in them. I have resurrected several siezed engines by pulling the spark plugs and and putting Mystery oil in the cylinders. The V design engines (like your V8) don't allow for total coverage but some Mystery oil will get in. Leave the Mystery oil in there for a couple of days and then try to turn the engine over by hand with a breaker bar (no spark plugs installed) . If you get it to turn you can try to spin it with the starter (no spark plugs). Once it spins over (and this WILL make a mess - the Mystery oil will fly out the spark plug holes) you can try to reinstall the plugs and run it. Be sure there are no leaks and watch your gauge. If you get no pressure shut it down right away. Did you find two gaskets under the oil filter? That's a common oil change "gotcha" that can cause sudden loss of ALL the oil. Even if you do get this running again the engine will probably have a lower life expectancy than it did before. And, of course, it might be too far gone to save without a rebuild. It depends on a lot of things like how many miles are on it, how hard you were pushing it when it ran out, etc. Best of luck - John

so your saying I have to take the valve covers off and the parts that are on top of there and pour this oil in? should I keep the oil that I already have in the pan?

 

[HiHood]

Save yourself mucho delores de cabeza (much head pain) by either rebuilding it or gettin another motor. It sounds pretty obvious that you fried it. I would recommend rebuilding it or having it done if you don't have the knowledge and or tooling. You don't want to get it running only to seize up somewhere too far to get to a friends' or whatever.
