Re: 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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
I would recommend sell it as well. Just list all the new parts you got for it. I also recommend craigslist.org 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.
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!!
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.
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!
