I've been browsing the forum for a while now trying to figure out my issue but can't seem to find an exact match for my problem. I was driving with a buddy in the rain a few weeks ago, we ran into a round about and decided to slide around it (I've had this car to 3 or 4 local drift events now, no problems) and when we let off and straightened out, the car started bogging and missing. I turned the car off immediately and towed it home.

Waited a few days because I was a little mad (I had just blown the motor in my 240 a few days prior to this happening) and pulled the plugs. Cylinders 2,3,and 4 all had what seemed to be oil on them, but when I wiped it off the plug it came off clear and smelled like gas. The plugs are brownish black looking but the electrode looks like it has been burning fine. Cleaned off the plugs, sprayed some brakleen down each of the tubes and let it sit for a bit. Re-installed the plugs and fired it up.

Ran like a top, but smoked a light whitish blue. Not white like coolant, and not super blue like straight oil burning.....it's kind of weird. The smoke didn't smell like straight burning oil....but kind of like gas. The car ran fine, bogged down a little bit and jumped right back to 2k rpms. Smoked the whole time.

It's an 06 s2000 with 20k on the clock, I've been religious with oil changes and general maint.

Thanks for any info or input you can give me, I'm pretty lost on this one.

 

Was it a hard right hand turn?

 

no it was a hard left but I was sideways the whole time so I wonder if it threw the oil at the driver side of the motor


edit: now that I think of it when I let off and came out of the slide it snapped back hard. the way it snapped it would have thrown the oil to the driver side of the motor. I've heard stories about people running into problems like this on the track but not like this.

 

bump, need some info!

 

I'd say the smoke is due to the stuff you sprayed down the tubes. It should clear itself within a few minutes depending on how much you put down there.

I'd be more concerned why there was oil on the plugs in the first place...head gasket/piston rings?

 

here's the thing, now that I looked at it again it was NOT oil. It was gas, and it WREAKED like gas. Makes absolutely no sense to me.....

 

Check check any sensors related to measuring air. They might need some cleaning

 

If the plugs are soaked in petrol, it's not getting burnt off in the combustion process, possibly because there isn't enough O2, or because whatever sensor dictates the amount of fuel injected is dirty/knackered.

 

just started it again, ran fine. I'm gonna check compression and go from there. I'll be back to update in a bit

 

Still waiting for the tester from a buddy, decided to start it and let it get warm. Smoked a tiny tiny bit until it got warm and then nothing. Drove it around the block and it pulled fine......I'm lost. I'm gonna check those sensors and wait for the tester.
