Unhappy I think it's headed to the junkyare but........

...who wants to take a stab at this?
Was driving my Jeep, a 2001 JGC limited with 4.7, the other day and upon accelerating i heard a kind of whistle....like how a turbo sounds winding up....didn't think anything of it except that 'hey, you want to be a turbo today huh?" :-) half mile up the road jeep starts shaking and hear a quiet ticking noise. Figured I'd blown out a tire and the ticking was some of the steel hitting on the wheel well. shut it down, got out, checked tires...NONE were flat. So I put up the hood, check the belt...nope. it's till intact. Got back in Jeep....dead. starter engages, but no cranking. nothing abnormal with the gauges except my oil pressure...which I'm told that my oil sending unit is probably shot because without jeep running, gauge shouldn't go up.....but that doesn't answer this problem. Nothing on dipstick...although a few days earlier it was okay. I pulled the serpentine belt off, since it's a piece of cake and tried to start again.....hoping maybe one of the pullies was locked up. still nothing. so, I'm thinking it's shot!!! I put a quart of oil in just for the helll of it.....barely showed on dipstick so I think it must have been about 2-3 quarts down. No clue where that oil went from the prior days.
So...who wants to give me anything else to check before I start parting it out as junk???

Re: I think it's headed to the junkyare but........

Was the oil pressure indication faulty before this started?
I would try and put a socket and an extension on the crank pulley nut and see if the crank can be rotated clockwise (standing in front of it) with not too much force. If not, remove all the plugs and try again. I would say that 3 qts low on oil should still leave enough oil for lubrication. No smoke from the exhaust before this started?

Also remove the radiator cap and check if there is any oil residue in there. If the oil wasnīt burnt of and didnīt leak out, then there are not so many places where it could go to.

Re: I think it's headed to the junkyare but........

It wouldnt hurt to run code self test and look for a transmission code.. Just for the heck of it. Its odd that it was idling when you pulled to side and now wont even turn over. Alt was charging I assume. Whine and shutter?, Id be thinking transmission. or torque converter.

Depending on how long it may have run without much oil, and how long it has sat since, might be able to salvage. When trying to turn the crank, don't move it very far, as you don't want to cause further damage.


NOTE: This is an old tactic, best used on antique GM stove bolt 6 engines or old Toyota 4 bangers, where they could run for years afterwards.

Drain the oil, and look for large bits of metal. If a lot, just give up.
Then, fill the oil with a mix of penetrating oil [or kerosene] and STP.
Pop the spark plugs and put about a teaspoon of kerosene/penetrating oil mixed with a few drops of STP in the cylinders and let it set for a few hours.

Then, try the wrench on the crank and see if you can turn it. If you can, keep turning it for several turns, hopefully the resistance will drop.

Then, drain the oil, new filter, and add a good oil brand before you try to crank again.

All you purist mechanics can now go get your Dramamine--but this old method does work--not that I'd do it on my engine except for long enough to drive to a junkyard or crate engine supplier.

Re: I think it's headed to the junkyare but........

It's been burning oil for the past two years...but I keep it up and changed regularly. The last time it was checked before this happened was two days prior and it was good. yes, the jeep smokes and has been because it's been burning oil. I will check the coolant for discoloration...it was drained and refilled a year ago and was good then...no indication of oil in it. I did do the key dance....I can't recall now what the codes were, two had been on there previously for emmissions and maybe an oxygen sensor. I had two or three misfire codes when I checked it after it broke down. I will put a wrench on the crank pully and see if I can move it at all and get back to you on that. The alternator is good and the jeep was showing normal voltage when the key was turned over. I think its very odd that I didn't have ANY gauge warnings when it went haywire(other than check engine for the previously two codes)....and the gauges are all still normal. I dont know if the oil pressure gauge was normal or not...to me it seemed to be working just fine. It was a friend of mine who said the gauge should not be reading pressure when the jeep isn't running. That's all I know about that. No low oil light. I went and bought a 2014 Malibu LTZ the other day...sure would have loved to have a new jeep, but this chick can't afford a $50,000 Jeep. :-( maybe someday when I'm done with college and have my accounting degree I'll be able to afford another Jeep. :-) Thanks for all the info.....I'll follow the suggestions and see what comes of it and post more info.

Re: I think it's headed to the junkyare but........

So, I put a socket and cheater bar on the crank pulley and notta....i used a lot of strength, and I'm a pretty strong chick..lol....it would not budge at all! Wish I could keep it and tear into it...just for the fun of it, but, I need cash so going to try to sell for parts. unless I don' t get any buyer...and then maybe I will tear into it. :-) might be fun to dissect it without the worry of screwing anything up!! :-)

Oh ow! Since it isn't that likely anyone would want the engine except possibly to offer you $20 bucks as a rebuild or whatever it is worth in scrap iron, it might not hurt to try the penetrating oil down the cylinders, and in the crankcase and let it set, then add a bit of STP and try the cheater bar again. I'd guess bearings over seized rings...

Re: I think it's headed to the junkyare but........

so, would this mean I need to pull all of the coil packs and plugs to pour the stuff in there? I don't really know much about engines. I'd give it a shot just for the hell of it. :-) I'm not real keen on selling to junk yard just yet. they are only paying like $180. Hell, I can take a few parts off it and sell on ebay or craigslist and make more than that.....:-)

Re: I think it's headed to the junkyare but........

Yes, you will have to pull the coils and plugs and pour a bit of the recommended fluid in. Not too much, but leave the plugs out while it soaks. You don't want to create a hydraulic lock when the plugs are in place and more fluid was poured in then volume available above the pistons.
