ParadiseMJ Posted January 28, 2014 Posted January 28, 2014 Well, just like the title says. I haven't really stuck my nose up to my dipstick before but I did yesterday and I get a pretty good whiff of *what smells like* fuel. Although I don't fully get why my oil would smell like gas. My oil level hasn't gone up or down. My injectors are fairly new (refurb'd) Ford injectors I got off ebay. Mileage seems normal, oil isn't thinned out. Just seems to smell like gas. My tailpipe does NOT smell like gas, I don't have much if any blow-by on my filter or anywhere else. *Let me qualify my sniffer*. I quit smoking several years ago and since then my sense of smell is all messed up. My wife can be burning lavender scented candles...and it will smell like diesel smoke to me. My dog can be dirty and soaking wet and will smell fine...except to everyone else. Skunks still smell like skunks though.
Jeep Driver Posted January 28, 2014 Posted January 28, 2014 Get a second opinion. If it has not thinned or increased or changed color.......or.........? I would not worry about it.
jimoshel Posted January 28, 2014 Posted January 28, 2014 Never trust the sniffer of an ex smoker. Just get a second opinion and don't worry about it. :thumbsup:
ParadiseMJ Posted January 28, 2014 Author Posted January 28, 2014 The vac line with the CCV is not old. It's been 2-3 yrs. since I replaced all the emissions/engine/HVAC vac lines. The line and orifice is clean/clear. I'll get someone with a good nose and go from there. I'm going home today to smell all the other cars dipsticks...see what I see (smell).

I don't mean any offence but maybe you should wait till dark to do this.....you know.....in case anybody see's :brows:
jimoshel Posted January 28, 2014 Posted January 28, 2014 I think he means the dipstick under the hood. Not the one behind the wheel. Steering. :yes:
Minuit Posted January 28, 2014 Posted January 28, 2014 :rotf: Jim, yxmj It's not something I've experienced personally, but I doubt you have a problem unless you have noticed a change other than smell. I imagine gasoline+oil would look or act out of the ordinary in some way. You said yourself that your sense of smell can be deceiving sometimes, so I would get a second opinion and not worry about it too much.
ParadiseMJ Posted January 29, 2014 Author Posted January 29, 2014 :yes: I smelt two newer cars...people do look at you a little funny when you're sniffin' a dipstick...same smell... :thumbsup: There's a sig line for you !
cruiser54 Posted January 29, 2014 Posted January 29, 2014 Old trick used on big rigs. Pull the dipstick. Let the oil drip on the "web" between your thumb and index finger. Does the oil spider out into every little wrinkle in your hand? If so, oil is fuel fouled.
ParadiseMJ Posted January 29, 2014 Author Posted January 29, 2014 Old trick used on big rigs. ... If so, oil is fuel fouled. ...good tip...and if the oil is fuel fouled, what's up? Compression numbers are good at last check at or close to 135 across the board.
Timeless Posted January 29, 2014 Posted January 29, 2014 Smelling gasoline in oil is pretty standard especially if the engine has not been warmed up and run for a while. Upon cold start some gas gets past the piston rings and into the oil. It accumulates a bit then evaporates out once the oil is nice and hot. If you take a lot of short trips, its entirely possible the gas is just accumulating into the oil. Otherwise, a slight gasoline smell is pretty normal and probably nothing to worry about unless the oil is thin/discolored or otherwise visually wrong.

Compression numbers are good at last check at or close to 135 across the board. Fuel is getting by the rings and into the crankcase. Leaky injectors are usually the cause. Have you done a fuel pressure test? See how long the rail holds pressure after shutting the Jeep off.

Posts 10 and 11 confirm the presence of gas in the oil.

By the time it was ready for an oil change it was so thin it wouldn't hold pressure idling after it warmed up.
