98 jeep grand cherokee oil problems

I have been having many problems with this thing. the new thing we have found is that the oil has gas in it, bad. i pulled the dip stick, wiped it on a paper towel and my lord it smelled like my gas tank. what could it be this time, and what do i need to do to put a for sale sign on it? it is an endless money pit. I just did a full tune up on the car.Distributor cap, rotor, plugs, and wires, changed map sensor, oil change 100 miles ago.has a new computer, crank sensor,exhaust manifold, exhaust, battery, breaks, and tires. I'm so tired of putting money in this thing. I'm at about $3,000.00, and paid another $2,500.00 for it. So we can say $5,500.00. I just need to fix it, and sell it. Do you have any other suggestions? If I can't fix it I will just part it out, and hopefully get some of my money back. Thank you for all your time and help!!

I would recommend sell it as well. Just list all the new parts you got for it. I also recommend which is free or carsoup which is $25 until it sells.

When gas is getting into the oil, that usually means that either the piston rings are worn, bad valve, leaky fuel injectors, possibly fuel pressure regualtor. It is usually bad rings. The fuel being dumped in cylinder is not being burned up and therefore getting dumped into crank case.

Also if your timing is off, and engine doesn't fire at the right time, the fuel will get dumped.

SOURCE: 98 jeep grand cherokee gas in oil

You might have a spark plug that is not sparking.  Fuel will still be sprayed into the cylinder and not ignite.  It will then just drain into the crankcase past the rings.  I would pull all your plugs and check the plugs.  If you find one that is soaked in fuel, it's probably the one.

98 Jeep Grand Cherokee, The low beam lights went out, the high beams work OK. Has anyone found the common problem yet with this issue? 101,000 miles.

If your headlight switch is the type you pull out, left of the sterr column on dash, switches tend to go bad, I replaced mine and only had 50,000 miles. try checking headlight relay in engine fuse box first.

The instrument cluster is dead in a jeep grand cherokee 98, everything else is fine, how do i fix it? I changed the fuse already and still dead all the instrumentation is dead, i have no readings, no gas...

I had the same trouble with my 98 cherokee and found the solution online. There is a circuit board in the domelight that can be unplugged, I haven't got a clue as to the relationship between the two but when I unplugged the circuit board my cluster immediately came back and has worked perfectly since.Hope this helps.

My 1997 Jeep Grand Cherokee cuts off while I'm driving.

If you have zero oil pressure thats a BAD sign, first have a mechanic check what the engines actual oil pressures are.

sounds like a bad pump, filter or both. Do some testing before replacing though, a bad crankshaft sensor can do pretty much the same thing! Parts are not cheap...testing is very important!!!

98 jeep grand cherokee black smoke

Either your too rich and gas is getting by the piston rings going into the crankcase(oil pan)or you have a defective fuel pump (even if it is new!!)IT'S one or the other!!Running the car very rich for a period of time will have fuel in the oil!! I run mind rich for the nos and smell gas in the oil when draining it and only have a few passes on the motor with the nitrous,but runs extremely rich at idle because the timing is backed way down and running a colder plug causes a rich condition!! Plugs will foul quickly also!!

98 Jeep Grand Cherokee - Won't run without holding gas pedal down

first thing to check is vacuum hoses. a split or disconnected hose can give you a stalling problem as you outlined.
I think you are talking about the blower motor? (under the dash) Not the fans at the front of the engine right? I don't remember if there is a relay for blower motor if there is, contacts may be burned closed. Is blower on with key in "off" position? (some designs leave blower on at all times, running very low speed.) I really don't see any connection between both problems but I could be wrong.

Jeep won;t fuel pump installed

try the fuel filter and make sure you have proper oil pressure!! Remeber if you have tried craking to many bad times then the plugs are going to be fouled out!! Means that they are going to be drowned with gas and need replacing!! Also make sure your fuel pump is coming on!! You should hear a hissin or a hummin noise back from the fuel tank!
