Gurus in the house.

Went for routine service this morning and after checks the mechanic said we need to change one the plugs. Car is Nissan maxima 97.

So on removing the plug holder (don't know if that's the name) noticed this black substance pouring from one of the holes. Looks like bits of charcoal but my mechanic couldn't explain what it is. So I took some pics.

That should be your evaporative control valve.

That's your purge control valve solenoid. It all allows for flow of gas accumulated from your fuel in your tank to go in through the intake manifold plenum. This gas has a storage house called the charcoal canister.in this case what I think is happening here is that the your car's charcoal canister has been over filled up with hydrocarbon so there fore the purge control solenoid valve keeps sucking up the hydrocarbon rather than the gas. What car is this by the way?

Its a Nissan Maxima 97. I had to let the whole bits pour out before he fixed back the plug.
Abeg, what's the consequence of the purge control solenoid sucking up the hydrocarbon? Though I haven't noticed any visible change on the car's movement

evaporative emission control valve. A controlled vacuum is pulled from the fuel tank thru the charcoal canister, before it gets to the intake. 

Problem here is the canister is defective and bits of actual Charcoal are being sucked up into the intake. This is not very health for the engine.

My suggestion is you replace the canister (good luck finding one ) or block off vacuum pipe from fuel tank (its crude but a better option)‎

This would kill your engine. Replace charcoal canister and have the your purge control solenoid changed as well. You would also need to clean up the vacuum lines.this is not healthy for your ride

Except the purge control solenoid valve (an electrical gadget) has screamed out with a code (P0443), let it be. Yes, the contents of the charcoal canister have certainly disintegrated. Have the canister replaced and the evap lines cleaned.

Thanks bro. For now I don't have any lights on dashboard. So I should have just the charcoal canister changed? I just did a simple test I saw on YouTube and the purge control valve sucks vacuum well.
