Engine rattling after driving a few minutes

Lets start off by saying, I am handy. I build/repair a lot of stuff. Cars... Just isn't my forte. So sit back and grab the pop corn for this one.

All started with my 98 sahara overheating after driving a while. Was told by a mechanic it was the thermostat. Looked up the fix, pretty easy. Took it out for a test drive, drove for 5 minutes seemed okay. Figure hey, lets pin the gas a make sure... Immediately car started to overheat, smoke, and oil went all over the engine (this is the point where i mention i have an oil leak, and probably had overfilled the oil in the first place).

So on the advice of a friend, a day later i lightly washed the engine with water to clean off the oil.

Took it back out for a test drive after letting drive for several hours, car had a hard time starting, and was clearly rumbling. Try to accelerate slowly and it hesitates/rumbles/doesnt go very much.

Bough fuel injector/water remover today told that was the fix. Drove it a few miles, the rattling begins. And progressively gets worse as the engine seems to get weaker & weaker, and finally gets the point where it stalls out while driving. Then comes the smoke.

So I am frigging stumped. Thinking its the spark plugs, or spark plug wires that need replacement. Though I do not know how that fixes this excessive rattling that comes about.

Your thoughts?

Just some basic questions... Did you overfill the engine with oil? By how much? You say oil went all over the place. Where did it spew out? When you replaced the thermostat, what kind of coolant did you put back in?

Have you checked your coolant / oil since all this happened with the overheating and oil getting everywhere? Is there any cross contamination?

Before the oil splattered everywhere, I couldn't tell you. Immediately after I drained the oil, and put 6 qts in.

It appears to have spewed out right side of the engine. Hard to tell it hit something/propelled because it made it to the left and right fenders.

I do not recall the type of refrigerant. More than likely 50/50

Didn't see anything, doesn't mean it was there though.

Mmmm good question.

Leaning towards knock, it only happens when pressing the gas.

Will try tomorrow. Attempted to start it today, engine wouldn't turn over. Might be the battery.

Video will be hard, it only happens after driving it a mile or so and when gas is pressed. Will attempt.

Well, I mean, it sounds like it could very well be a blown head gasket. Exhaust leak maybe?

Get under the with some fully concentrated simple green and spray everything down after you spray it with a hose.

Get a brush of some sort and try to clean things up down there to see if you can see where the oil is leaking. Obviously, cover your alternator, distributor if you've got one (97-99), your fuse box, PCM, and your intake. This should help track down your oil leak.

Used concentrated degreaser when I washed it down the first time. Cant say I really covered anything tho. It wasnt having a problem starting, or hesitating when pressing the gas. Ever since the car just sound/reacts weak.

Have had an exhaust leak for years, don't think theres any relation to it.

And the oil leak, prior to changing the thermostat and washing down the engine was coming from the rear main seal.

Then it doesn't make sense for oil to be all over the top of the engine if the leak came from the rear main seal. Now, your rear main may be leaking, but that's not going to cause oil to be all over the top of your engine.
A video of you driving the jeep in the cabin would probably be the best.

My thought was it was overfilled and it shot the oil out of the dipstick. Since then, I had did an oil change. Now the knocking, loss of power, smoking is the issue.

Okay. Pretty sure oil won't shoot out of the dipstick. You need pressure behind it and if you've ever seen a tj with no oil pan, you know the tube that the dipstick runs down, is a good 5 inches from the bottom of the dipstick.

So, not seeing that theory.

This smoke, it's white? Blue? Black? Does it smell like weed eater exhaust?

Also, you adde some sort of water be gone business. What's that? Where did you add it? Is it gone now?

I would start with a compression test, that way you will discard head gasket, valves, rings and any other issue with compression/power, after that check your catalytic converters, when they go bad can cause all kinds of symptoms.
Let us know what you find.

went to go start it today (presuming the battery is dead now) and noticed the pcv valve is dislodged from the engine. Looks broken.

MKK. so thats your CVC valve(different from pcv valve, dont ask what the difference is) as Chrysler calls it. If that becomes blocked with oil, sludge, shit, youre in trouble.

Im guessing it was blocked and it came off spewing oil out of the valve cover..

You didn't notice this when you were spraying your engine down with water???

Go grab that part and fix it and see what youve got after that.

Neg I think the hose was still in the hole when I was. Tho when I was starting the car yesterday and it wouldn't turn over I was giving it gas, thought i heard a pop in the engine. Maybe that was it coming off.

Okay, by turn over, you mean crank but no start?

If it isn't even turning over, your spark plugs aren't causing the problem.

Hopefully someone will chime in on how to jumper your battery to your starter to see I you can get it to turn over that way.

Key in ignition, everything turns on lights ect... Try to start "won't turn over" while jumping... Gave up, accidentally left the headlights on for a few minute battery dead at that point.

So... Replaced the pcv valve.. Apparently there is not a cvc on a sahara.

Went to go start it, batter dead. Tried to jump it, and won't turn over. After you disconnect the jumper cables it dies all together.

But when it was attached it tries to turn over. Don't quite get there, and surprise surprise.

MY DIPSTICK SHOT OUT!.

See the link for the video... Stumped.

It's a cvs valve. Sahara, sport, there's no difference engine wise. Your local part store can call it whatever they want.

Okay, your dipstick shot out. You're pressure in your crank case isn't being released.

Also, your jeep won't run if the battery was just dead. You have to keep it alive by giving it gas until the computer re learns how to run.
