I'm new to these boards and I only bought the Jeep yesterday... I paid only $300 for it and everything works... except I fear (assumed actually for the price I paid) that the engine is either on it's way out or driving it back home finished it. The gauges are jumping around randomly... every single one of them... when the engine runs, it's extremely rough, sounds worse than a diesel engine... When I got home I realized the oil gauge was empty... it wasn't when I left... I only drove maybe 30miles to get back home... I also noticed the dipstick isn't in there anymore for the engine oil... the small yellow cap is in, but no dipstick and alot of smoke is coming out from in there after the engine warms up. It also stalls if you stop at a light, clicks when you try to restart it, but eventually does restart... and it's backfiring like crazy...
Now I'm just gonna go ahead and assume I need a complete swap of the engine... but is there anything I could try first? Fresh new oil, filter & dipstick? I don't have far to go to get to the garage for the swap and I rather not pay +$100 to get it there...
Also, when I brake it jumps around, I'm assuming warped rotors?
If you just need to tow it a short distance, put the transfer case in neutral and pull it home with a tow rope. Saves you money and If you have to buy the tow rope it is money well spent for the future when you will be the one lending a hand.
Is that supposed to look like that?
I picked up mine for $600 and it had a knocking engine. I spent about $1000 and rebuilt it myself. That is with boring it .030 over with new pistons,cam,oil pump,lifters, gaskets, sending the head out to get checked for cracks and milled .008. And i did a valve job on it. But I aso work at a dealer and have access to some great equipment and know a lot of people to help.
^ Video of the engine running... I added 6L of oil... I'm assuming the gauge reads 5.4L because that's how much oil fits into the crankcase/filter/etc...? Anyways you can see in the video it reads about 4 after adding 6L... it's starts great and runs hard, but runs when it has oil in it
rocker panels are rusted out, other than that there are 2-3 fist sized spots that have been primered... everything works, cept the back wiper (new motor) and blower... also the back door won't open, but I read somewhere that that is a relay issue, and there is a way to override it?
I watched your video and cannot see the guage you are referring too, and although I'm not familiar with the WJ's, I would be surprised if there was an 'oil level' guage on the dash. Could you be you be confusing it with the 'oil pressure' guage? If you lost oil pressure and did not immediately turn off the motor, that would be a cause for the bearing failure in your motor.
Anywho, that motor is toast. That noise sounds like rod knock for sure. Stop messing around with it and stop wasting money putting oil in it.
Good judgment comes from experience, experience comes from bad judgment.
X2 on the gauge reading, it is oil pressure not volume you are looking at. and a little over 40 would be about normal for a 100,000 mile engine. First have your codes scanned and find out what the errors are for the check engine light and then maybe a compression check. It sounds like either a rod knocking or maybe a broken piston, burned or broken valve or similar issue. You can either rebuild that motor or buy a used motor and replace or part it out for more than you paid. The rear differential should net you $300 or so.
Is that supposed to look like that?
So what should I do? Buy a rebuild kit? I looked at a few, but I was wondering what kinda kit to get... there are different ones, I'm assuming a Master rebuild kit? Is it cheaper/does a dodge pickup 4.7 rebuild kit work?
I live in Sherbrooke, QC by the way... craigslist isn't really used around here... are there any other engine's that would fit "easily" in these WJ's? If I can get a used engine for less than a rebuild, I'd rather go for that... but the 4.7L WJ engine is impossible to find it seems...
