Very slight oil burning smell when coming to a stop. Is my list of stuff to check correct?

The phone is actually a good idea, provided you can get clear video. A sticky pair of gloves should help with fumble fingers. Just ask some NFL athletes. You could even tape it to a meter-stick or metal rod or long angle.

Does keeping it on recirculate have an impact? If you can't smell it outside the car, but can inside, either you have a leak somewhere in the ventilation system, or the smell is emanating from a source that is close to the intake on the passenger side of the firewall.

Still can't locate anything specific, though I'm starting to notice a bit more of a raw gas smell too. Still doesn't seem to be coming from the exhaust pipe, it's like it's under the car. Sniffing around the top of the engine is still inconclusive, it just smells like hot metal, not burning oil or raw fuel. Only 22k miles, I don't think I've killed my stock cat, and it wouldn't explain the burned oil smell.

Outside the Box: After awhile (weeks) it got to the point of eye-watering... and originally I thought the smell was emanating from cars up ahead of me in the morning traffic. Longer story short, the smell was melting plastic from a wire harness for the blower motor. The metal was defective and had corroded. So the contacts were basically resistors, converting a significant percentage of the energy flowing through them into heat. This was a past car of course; not a FiST.

Well a new clue. I just popped open my oil cap after a drive and it smells like I’m running straight gas as oil :| not slightly gassy like an old lawnmower, but like pure gas after ~30 minutes of driving at 67 Fahrenheit ambient. This doesn’t seem normal, not on any of my other cars at least. Just changed oil about 600 miles ago. Poor fuel economy and more than usual popping during decel. From reading sounds like maybe HPFP?

Evap system functioning normally? Fuel evaporates incredibly easily, rapidly... even more as you open the cap and lower the pressure in the engine case. But then, it's not unusual to see vapors coming out of the hole when removing the oil cap. Check again after a bit.

Subbing to follow. This might be the reason for my bad fuel milage lately. ( 30 mpg regardless of temp sucks.)

The best way to deal with this is send in the OIl sample to Blackstone laboratories to give you definite proof too much oil in the fuel.

mom getting like 20mpg, but it’s all surface streets, very rarely freeway

 

[PunkST]

My biggest tell tale symptom is the fuel economy drop and the excesssive popping and banging on decel. ( loud enough that i worry about being pulled over, even though i have a stock cat still)

 

[Clint Beastwood]

I checked after it cooled overnight and it’s still like I just sniffed my gas cap and not the oil filler. Blech.

need to pull off my turbo smart dv and probably my intake and take it in. Really wishing I hadn’t just finished selling off most of my other cars right now lol.

 

[PunkST]

When you do keep us updated. As your repair may be on my list of things to try

I finally found some oil, like fine mist around the oil cap. It’s not drips or spill but a fine mist. I’ve never had an oil cap leak, but the crankcase is pressurized, right?

 

[SteveS]

Crankcases get pressurized from blowby, but that's the purpose of the PCV valve, to release the pressure back into the induction system. If you are having excess crankcase pressure, it's either an indication of too much blow by (i.e. worn, broken, or improperly seated rings) or not getting rid of the pressure (i.e. blocked or stuck PCV valve). The oil smelling like gas would possibly suggest excess blowby of unburned fuel. Or maybe even a cylinder where the fuel isn't burning and you end up washing the cylinder wall with fuel.

[TyphoonFiST]

If your rings are worn....you will usually also be burning it. So if the oil level is proper I'd factor that out. I'd also recommend getting an oil sample done as this will tell you what is in the oil and how the engine is wearing normal or abnormal. It will tell you if your having abnormal amounts of gas in with the oil. FYI.

Checked again, oil changed recently and now it’s reading way high, cold and rechecked hot. Smells like gas. Probably can’t take in til after Xmas.

same valvoline place that always does it. Had me change the oil because of the burning smell, about 2-3k earlier than usual. They didn’t overfill, they always bring me the dipstick to check.
