My Mother-in Law has an 89 or 90's era Chrysler mini-van with I think the 2.2L engine. The oil light has come on, the oil level is full but has a Strong gasoline smell. Anybody know what I might check-out first?? PCV valve?? Intake gasket?? Thanks for any help :TU:
If it has a fuel pump on the motor(I am not sure)I wouldn't rule that out.I had a GS 350 that the diaphram went out of the pump and it leaked fuel into the oil. Just a guess.
That's the first thing I thought of, fuel pump If the pump is by the tank, what else could be in the fuel system that could also get at the oil? Cracked intake manifold? leaky fuel rail next to a leaky valve cover gasket? Some unburned fuel gets past the rings, but if you can smell it that strongly, I'd guess it has to be more than worn rings
Kenny, That's usually from flooding. Ordinarily, I'd think needle/seat problems in the carb, but that minivan should be fuel injected. Where's the fuel pump on it? If it is mounted to the engine, it may be leaking into the crancase. I'm just guessing here. Ask Ronny, he sells Chrysler minivans all the time, and is familiar with them.
Thanks for the input guys, I thought of the fuel pump also, but I think this one is in the tank. I'll be going over to look at it later today. I just thought I'd get some other thoughts on the matter. I'm not even sure of the year of the van. ou: o No:
I would change the oil and check it daily for a week or so. Pretty hard to get gas in the fuel on that one. If the light is still on after the change I would look and the oil pressure switch, it could be the problem. If you could test the pressure with a gauge that would be a good idea. If you do not have a test gauge you could use an old under dash one, if you have one of those laying around. Good luck John
Pull the vacuum line off the fuel pressure regulator while the engine is running. Look for fuel leaking out of the vacuum port on the regulator, if the diaphragm failed then fuel will leak out. It may take up to 30 seconds to leak, or possibly right away. I have seen that problem on a few Chrysler products.
Fuel pressure regulator would also be by first guess as well. Chevy trucks I know have a real problem with those. Mike
Yeah, but the vaccum hose goes to the intake. The fuel would have to get past the rings to get in the crank case. Definitly worth looking at.
I just got back from the van. It is a 1991 Dodge with the 3 L v6 engine. First thing I did was check the oil dipstick, no evidence of gas at all!!! I was assuming my wife Mary knew the difference,she is the one who discribed the "gas in oil" symptom. Once the engine is warmed up the "oil" light does come on when idleing or coming to a stop, it goes out with just a touch of the gas pedal. Oil level is full,no knocking or ticking from engine. I suspect the sending unit or the wiring connection. I didn't get to inspect it cause its too cold out and I'm not sure where it is. The area around the oil filter is soaked with oil and very messy from sloopy past oil changes. Any thoughts??? o No:
Yeah Kenny, Maybe just a bad sender unit. Low oil pressure usually manifests itself with engine noise. You could always put a real gauge on it and tell for sure.
