Default Questions about residue on spark plugs... pics...

I'm not going to embed the images because they are pretty large in general.

I pulled my spark plugs out and my valve cover off today to check up on it. When I pulled my spark plugs out I noticed they were really white and had some sort of residue built up on them. What would cause them to become like this? I replaced all the spark plugs but I would like to prevent it from being like that again.

Also do you think the head looks clean or does anything not seem right about it?

As a third question... I noticed I've been leaking oil and... potentially more oil. For awhile I've noticed that I go through about a quart every one to two weeks. I just thought the engine burned the oil. Today I looked at the ground and noticed that I had two puddles underneath the car. One below the oil pan and the other below the transmission/motor. I put my finger in the puddle under the oil pan and it was a clear/black color and smelled like oil... so I assume it's oil. I check the other puddle. It's mostly clear but still smells like oil. I use 10w30 full synthetic in my motor. At the moment I have the same in my transmission just because I've been lazy about putting my 80w90 gear oil in it.

I think the oil leak is coming from the oil pan. I torque the train bolt to the correct specifications but oil seems to be leaking out around it still.

As far as the transmission I didn't really look but I have no idea why it would leak.

It only leaks a very very small amount.

Any ideas and opinions are appreciated.

Thanks.

those pics on that site don't show too much of detail in the images... and none really match mine... mine are white... not yellow/brown... and they have a lot of residue built up on them... but it's all white

As far as the leak goes, did you put a new gasket on it?

And for the spark plugs, when ever you get white (ash) on the plugs, normally that is unburned crap from the gas. What to check.... I would first replace the normal... Plugs, Wires, cap and rotor. Also, have you made changes to your timing? Either way, check the timing... also, when was the last time you changed those plugs? Also, do your self a cheap favor, and run a bottle of lucas gas cleaner through it on a full tank 89 or better octane gas.

There's a gasket that goes around the drain bolt?

The plugs were changed about 5-6 months ago. No changes were made to the timing but i 'think' the timing belt may be on too tight because it makes a whining sound. I always run 89 octane. I'll pick up a bottle of lucas gas cleaner though and give that a try next time i fill up.

I'll look into the wires, cap and rotor.

On some models, Ive seen a small gasket. Or on some after market replacement bolts.


If your leaking from the drain bolt, replace that bolt. Its not seated good.

Well, like I said. The white ash deposits, its always from unburned crap in the gas.

Also, one last thought. You didnt mention any driveability problems at all... hesitation, rough idle, etc. It might be worth one day, to do a compression check.

You didnt mention what Year/Make/Model/Mileage of the car.

well... i have a busted motor mount so its hard to say for hesitation since the motor jumping back is a pretty big hesitation...

its a 1998 civic ex... car has about 103k miles on it... the motor is a d16y8 and has about 75k miles on it...

idles not rough... its smooth...

it used to hesitate a lot before but i had a broken knock sensor... since i changed the knock sensor that seemed to get rid of all hesitations (other than the motor mount)...

i looked at it and theres a washer between the bolt and the oil pan... maybe the washer needs replaced and the bolt too?

Theres a crush washer that belongs between the bolt and the oil pan. Go buy a filter at Honda and they will give you a few with it.

Plugs = running lean
Head = looks normal, just tarnished a bit.

Ah! bad knock sensor.... how long ago did you change it? You know that could have been a cause for the fouled/ashed spark plugs! I think you may have already fixed your problem.

Yea, you could goto honda.... but its a $0.75-1.25 washer. You could pick it up anywhere. And honestly, I would change the bolt and washer the next time you do your oil. And after that, i would say change the washer every 3 oil changes. Its just good practice to do so. (and if you dont change your own oil, most places do change that washer for you. unless you goto those $9.99-$14.95 quickie job places. There a lil cheap, and thats on corner they cut.
