2002-2006 Nissan Altima: Why is there oil in the spark plug well?

Tue, 20 Jan 2026 12:18:20 -0700

2003 Nissan Altima, 3.5, 110,000 miles.

Went to change the spark plugs after obd2 read a misfire in cylinder six, when i removed the ignition coil it was soaked in oil, as well as the spark plug when i removed it.I Wiped out most the oil and finished replacing the plugs. After starting it the first time white smoke was pouring out the exhaust for a min or so and stopped,and the car drove fine.

However today i started it up and it was misfiring again, worse than before and this time the check engine light kept flashing all the way home, p0306, cylinder six misfire. What could be causing oil to get in the spark plug well? Im assuming the oil is causing the misfire.

Please Advise

2002-2006 Nissan Altima: No acceleration when car in Drive

Tue, 26 Sep 2023 01:57:09 -0700

Started car, went in reverse and when put car in drive car limped and no acceleration. Car check engine light came on. Car slowly rolled until I parked it again. Rested car for several minutes and started again and was able to accelerate to get home. Check engine light stays on. Could it be bad gas, clogged fuel filter?

Tue, 05 Aug 2025 09:37:35 -0700

We just bought a 03 Nissan Altima with 73000 miles on it. It was barely driven by the elderly lady that owned it. We went to start it and it will turn but won't fire. Any ideas? We can't take it to get it scanned since it won't start, and I don't want to pay to get it towed somewhere. HELP!!!

2002-2006 Nissan Altima: Won’t go over 2rpm

Wed, 30 Jul 2025 09:18:33 -0700

My 2006 Nissan Altima won’t accelerate over 2RPM, when it goes above that it starts jerking, almost feels like it’s choking. I just changed the Camshaft Sensor because it wouldn’t accelerate when I pressed the gas pedal at all. It now goes, but only until it reaches about 21/2 Rpms. It has a new MAF sensor and just replaced the throttle body sensor. Please help I don’t know what else it could be. I’ve recently learned about something called fail safe mode? Could that be my problem? If so, how do I fix that??

Wed, 17 May 2023 03:43:51 -0700

I had my valve cover gasket fail and it leaked oil into my spark plug well. So I replaced the valve cover and that spark plug boot that was full of oil, installed new spark plugs and now the car won't start. Just turns over... Could the oil in that spark plug well have killed my coil pack? And would that keep my car from starting?

2002-2006 Nissan Altima: Driver Side low beam light not working - replaced lamp & checked fuse

Thu, 13 Jun 2024 23:26:28 -0700

I have a 2006 Nissan Altima.

The Driver Side headlight went out. High beam works fine but not the low beam.

Initially thought the light was burnt out so I replaced it with a new one… Next I checked the fuse box. I replaced both the 15 and the 10 amp fuses for the H/L Hi/L and and H/L Hi/R. Still nothing.

I’m guessing it at this point it is a wiring issue, however if others have tips on how to troubleshoot and narrow this down quickly, I would be very appreciative! HELP!

In advance, thanks

It would appear that the driver's side headlight fuse is blown. The problem is that neither fuse box has an indication as to what fuse belongs to the headlights.

Hello

My parking lights came on randomly and now will not turn off. Any ideas?

I was going to pull the fuse but an actual way to fix it may be more helpful.

2002-2006 Nissan Altima: Why does my car still smoke?

Thu, 08 Sep 2016 19:30:22 -0700

Car suddenly started smoking, checked sparkplugs and had oil in one of them. Had to replace the valve cover, but the car is still smoking from tailpipe. Looks like white smoke. There is nothing abnormal with the oil or radiator. What should I try next? Thanks for a quick reply.

2002-2006 Nissan Altima: What could be causing a cylinder to misfire? code 0306

Fri, 09 Apr 2021 20:40:59 -0700

When starting my 2003 3.5 altima, it runs very hard. the whole front end was vibrating. As i continued to drive the "service engine soon," light began flashing, but then went away. After driving for about a mile, my car was driving normal. When i got home i manually got the code by putting the EMC in diagnostic mode, i came up with 0306, which appears to be misfiring in cylinder six. What could be causing the cylinder to misfire? How should i go about fixing it?
