Q: Cylinder misfire and burning oil

asked by on

I've had my integra go though a scan tool already but forgot what the fix for the car was. My integra has a misfire in cylinder 4 and can't remember the part that I needed to order. The problem isn't spark plugs, I'm sure it's the engine part that goes with the cylinder. My car has been misfiring for about a week now and I've noticed that there's a smell of burning oil that I can smell through the vents. Especially when after idling at a light...is this from the misfire? (Pretty sure it isn't the PCV valve because it wouldn't come through the vents right??)

My car has 157000 miles.
My car has an automatic transmission.

Hello. From your description this can be caused by a few things. The oil smell tells me that your either have an external oil leak that is causing this or you may have a valve seal or piston ring problem that will require some serious engine work. I usually check the engine for any external leaks as oil getting on the ignition system components will cause it to misfire. If there are not any external issues then I do a compression test to see if the problem is internal. If you are planning on having this misfire and oil smell diagnosed, consider YourMechanic, as a certified mechanic can come to your home or office to take a look at it.
