Jeep - Grandcherokee :: 1998 - Oil Has Gas Smell / No Smoke And Knocking When Shut Down
Feb 19, 2013
I have a '98 Jeep Grand Cherokee 4w with a 5.2l, it has approx 145,000 miles. It leaks a little oil and when i recently checked it (level was good), it smelled of gas. It starts easy and runs great with no smoke and no knocking when shut down. I've read it could be anything from rings to a stuck injector. I drive it on short trips now, only occasionally going out of town. It is due for an oil change but I would like to have a solution before driving it more or getting the oil change.

I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. Is it something to do with the wheel bearing, but that does not seem to be the case.???

My 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.

We have a beloved 1995 Jeep Gr Cherokee 4L that was our first new car! We have babied it for many years. It now has 173k on it. We took to local Jeep dealer to get all RECALL items taken care of and to have it checked out completely. It was pinging on acceleration and hvac wasn't working. They kept it 5 months and finished all recall stuff and replaced the ENGINE TEMP SENSOR. They also recommended a new trans and a new AC. Since my niece wants it; and she loves it like we do; we took it to an honest transmission shop.
They said trans was fine just needed oil pan gasket, rear main seal and an elec engine diag because trans and engine were not speaking to each other. Now our JEEP is home; sits in driveway all week. When we start the car on Saturday we still have WHITE SMOKE then after driving awhile it goes away. Does not leak oil; does not need coolant; has NEVER over heated. Engine sounds great and it runs great. Had it tested for head gasket a couple of years ago and they said pressure was fine. We have never had to put coolant in it. The dealer and other Mechanics said nothing.

I have a 95' Grand Cherokee, V8 5.2L. Recently, it started overheating and was diagnosed as a head gasket issue at a shop. I ended up replacing the head gasket, thermostat, and water pump. (The radiator, top radiator hose, and radiator cap were replaced within the last year as well.) Despite the repairs, the coolant in the reservoir does not move. The Jeep overheats and there is a squealing noise coming from what may be the water pump. There is also a slight leakage of coolant near the water pump bypass hose, but does not seem to be coming from the hose itself. What else am I missing?

I have a 2005 Jeep Grand Cherokee Laredo. I took it to the dealership on June 30, for a routine oil change and other maintenance that was due. They did a cooling system flush, and oil change, a power steering flush, and a brake system flush, along with a multipoint inspection, and replaced the belt and tensioner. On July 18 on my way to work in traffic, the vehicle completely shut down with no warning signals. Shortly after the check engine light, the oil light came on. Until then, I had not noticed any warning lights.
At this time I reached down to get a bottle of tea from the passenger front floor board and noticed a slightly oily pink brown liquid on the plastic floor mat. When it was towed to the dealership, they tore the engine apart and reported that the engine overheated, the valve seats came off, the valves hit the pistons splashing metal onto the cylinder walls and requiring an engine rebuild. Is the dealership responsible for not having discovered whatever problem caused the engine to break down? Or causing it somehow during the maintenance on June 30? They feel it is not related.

I have a distinct coolant smell inside my Jeep (2009, 60k miles). I popped the hood and couldn't spot any leaks nor was there any fluid underneath the vehicle. I took it into a mechanic and they smelled the same thing and put the coolant system under pressure (as well as doing a visual inspection), and could not find any leaks nor was there any evidence of fluid by the vents. They also noted that my coolant levels were still full and I had not added anything to the car. The current theory is a pinhole leak in the heater core (the smell is definitely worse after the car has been driven a bit).
I have had one suggestion to add Bar's Stop Leak to the radiator, but the mechanic said this was a Bad Idea (his argument being that since there was no visible leak in the system it would likely just gum things up). Since the vehicle seems to be otherwise operating fine, I'm hesitant to replace the heater core, but there's a good chance it's still under warranty, so I could go that route.
So, could it be something other than the heater core? Should I have that replaced or would the Stop Leak be a good idea?

1998 Jeep Grand Cherokee, ~130k miles, 6 cyl. engine. Returning from a trip this morning, I glanced below my car and saw a small (~3/16 inch diameter) rubber hose dragging on the ground. I traced it back and found one end connected to the top of the front differential. (Photo below). There's at least 2 feet of hose before the break. Despite searching, I could not figure out where on earth the other end of this end connected to. It doesn't work for that what's left of the hose is long enough to reach just about anything on the driver's side of the block.
The hose doesn't leak fluid, even with the engine running. I checked oil level, transmission fluid, coolant, brake fluid, power steering fluid, and windshield cleaner (I was getting desperate, OK?)-all levels were normal with no signs of contamination. The car drives fine-I possible drove up to 200 miles before I noticed it, and made the last 20 back home with no issues. (I was driving in RWD mode though). Where this hose is supposed to run to? I'm assuming Chrysler meant it to connect somewhere.

I get more or less constant wine-like odor in the salon, as well as intermittent burning match (sulphur?) one. These seem to be seeping from the outside, through the ventilation system. The car has a new radiator, and the heater core, there are no apparent coolant leaks.

I have an '08 Grand Cherokee Laredo, 3.7L V6 with 74,000 miles on it. Recently the exhaust/muffler have been getting loud, and during my state inspection the guy said it would probably need a new muffler/pipe in the next few months. That was about a month ago. Since then there has been an on-and-off horrible plastic/chemical smell in the cabin some of the time. My wife drives it about an hour to work each way, and she says sometimes it gets so bad she has to open the windows (in 20 degree temps....) or she gets a headache. She describes it as a "formaldehyde smell" and says it tastes kind of sweet. To me it's more like a burnt plastic/chemical type odor. I checked all underneath but saw no plastic bags or anything else odd. Nothing unusual under the hood. No visible smoke. I have an appointment in two days to have the exhaust fixed. My question is - is there any way this weird smell could be exhaust related? I am hoping so, because otherwise it's a total mystery. It's definitely not an "exhaust" smell as I know it.

I drive a '98 Jeep Grand Cherokee Laredo, 6 cyl. engine, ~130k miles. I noted a slow loss of power steering fluid a while back and, after hillbillying it for a while (money was tight, and there was a sale on gallon jugs of PS fluid), I decided to address this problem properly and fix it. I added UV indicator dye to the PS reservoir and drove around for several days, hoping to pinpoint the leak. Well, what I found was wherever the fluid is leaking from, it's in a position to be blown by the radiator fan, turning the inside of my engine into an ultraviolet Jackson Pollock painting. (That, or I really am leaking power steering fluid from my #1 spark plug wire). Any tips on how I can pinpoint this leak?

I was driving my '98 Jeep Grand Cherokee Laredo (6cyl 4.0l 4 wheel drive) on the freeway when it, very suddenly, started shuddering badly. The check engine light came on and then started blinking. I pulled right over and shut it off. I stared it back up and the engine is misfiring badly. I had a code reader with me and it's showing three codes. A random misfire, a cyl #5 misfire, and a Cyl#6 misfire. It will sit and idle (very roughly obviously).
There was no drop in RPMs, oil pressure, voltage or anything when it happened.
I got it home and replaced the distributor cap/rotor, all six spark plugs, and the plug wires but there is no improvement. I cleared the Codes and re-read them and got the same errors again.

My mother's 1998 Jeep Grand Cherokee (60 k miles!) has developed an annoying slow drip at the rear main bearing (6 cyl). Are there any additives that are safe and might slow this? She just had the oil changed, so it's not a good time to be talking about high-mileage oil.

I drive a 1998 Jeep Grand Cherokee, 6 cylinder engine, with about 120,000 miles on it. I used a code scanner and pulled a P0138 code-bank 1 sensor 2 O2 sensor high voltage, if I'm correct. First of all, it looks like this sensor is after the catalytic converter, right? So I think I either have a bad 02 sensor or a bad catalytic converter. What are the consequences of driving around without fixing this? Will I see any reduction in fuel economy, or any potential long-term problems elsewhere?

I have a 1998 Gr Cherokee with an automatic tranny. It is slow to shift when cold and the overdrive shifting works reasonably well but I have been told by a reputable mechanic that the tranny needs a new tranny filter at over $1000. My latest check of the tranny fluid and the level and quality indicates both are good. Should I replace the tranny filter?
Also, for the same above vehicle, when I put the vehicle into a moderately hard turn (right and left), the front wheels audibly click and you can feel the click vibration in the steering wheel when happening.

1998 Jeep Cherokee sport ... My mechanic tells me that my #1 fuel injector is always spraying and that that is why the jeep runs rough. This is after he already told me that my injectors were clogged and needed to be replaced (which he did). When the car is idling for a while, the exhaust really begins to smell like gas, so this seems to make some sense to me, unlike his previous diagnosis. But now he is telling me that I need to replace the computer to fix this problem.

I have a problem with my jeep grand Cherokee Laredo 5.2v8 losing oil pressure when the engine reaches normal operating temperature. the jeep sat for 2 years but we got it to run. when normal engine temperature occurs, the engine drops oil pressure and stalls. I have changed fuel pump,oil pump and oil pan gasket. also ran a cleaner through the engine. it doesn't matter if its winter or summer. the only way I can keep it running is to keep my foot on the gas pedal. if I don't do this the jeep stalls. a mechanic said it was the bearings. I don't believe this because there is no knocking noise when the engine is running. it has 103663 miles on it. it has just city and highway miles on it. never has been off road.

My wife says our 2002 Grand Jeep Cherokee very rarely hesitates as it moves from first to second gear (once every week at most). I've never felt the problem, but she says its happens when from a dead stop into 2nd gear. And she said there are no other times when the vehicle hesitates (fine in every other gear). No other weird noises and the power seems fine. Its an automatic transmission and I've had the fluid and filter changed recently. What it is? Transmission? It is due for some new spark plugs... any chance it could be that?

About a year ago the oil stopped showing on the dipstick of my 95 Jeep Grand Cherokee. It is the original dipstick. I have changed the oil, filled it according to manual. It runs well, engine has no ticking (unless its low on oil, then I add a quart), pressure is fine. Just no way to check the oil !The tube is still attached from looking at the outside.

Last summer my wife's 2000 Grand Jeep Cherokee began shutting down while driving (electric stays on) on early hot days after about 40min of driving; even when the AC is off. About 10min later we can restart as before (before that it won't even crank). Over the winter the problem went away but returned again this spring/summer with the hotter weather (>80C). Its not the no battery or alternator and no one can seem to figure out the problem.

I'm having an issue with my 93 Grand Cherokee with 193k miles.
The RPMs will fluxuate and even drop to 0 at times and the whole Jeep with shudder and shake and then the RPMs will return back to normal. It could just drop down once, or several times in a row. I've even had it completely die a few times and I'll have to restart it. It's the worst when idling or driving slowly, like through a drive through or a parking lot, but the Jeep will still give a small jerk at times during acceleration as if it's trying to do it but can't completely.
I know next to nothing about cars but I have a friend who has assisted me with few things. We changed the fuel filter which he said looked like it may have been the stock fuel filter. He hooked up his compressor and blew all kinds of black garbage out of it and concluded it definitely needed a new one. He told me just to run it and see how it did, which it did fine for awhile but today it seemed to be acting the worst ever with it shaking and shuddering and trying to die but it didn't. He also looked at the spark plugs and told me that while they were aged they didn't look bad enough to be worth the money replacing...
