black buildup on spark plug threads?
I just replaced the spark plugs a week ago cause apperently the former owner never replaced them in 4 years, and i checked them today and there is a dry black buildup on the first 2 or 3 threads, contact points are still clean, the original spark plugs were white, and prolly about .06" of clearence between contact points so i'm assuming thats why they were getting so hot, could i b burning oil? oil level does look slightly lower than full, changed it about a month ago, also i noticed that if i rub my finger in my exhaust pipe at the back its all black

Sounds more like carbon to me - Dry/Black. I would bet you are tuned too rich.
I would also bet that Seafoam is not the fix.

Re: black buildup on spark plug threads? (alotawatts)
ya, i'm thinking its the ignition timing, just incase i'll check all sources, do a comp and leackdown test, but my money is on the ignition timing, when i had my tach in it always idled at 1000, supposed to be 750

Re: black buildup on spark plug threads? (Civicse)
any body have any more opinions on this before we put this thread to rest? sounds kinda of abnormal for a 2000 civic to b burning oil so early? from what i know the previous owner didn't have the oil changed regularly, i'll make sure i double check with honda though.

Way the helll wrong. If he was burning oil the plug would not be dry. There would be an oily sludge buildup on the plug.
He is running rich, that is all.
If you have access to any type of data logging hardware or a scan tool I would reccomend taking a look at o2 sensor data and long and short term fuel trim to see how much more fuel is being added.

i don't have any scanning tools, should i still check my timing and adjust idle though? and as for running rich can any shop with the proper tools fix this or is this something honda has to do? thanks

Re: black buildup on spark plug threads? (Civicse)
oh and for the black residue in my muffler tip, is that anything to worry about or just some carbon from running rich?
