can anyone tell me what it means where there are white snowflake looking specks on the ground strap and porcelin? this is the first time i have seen this on my plugs so i wanna know what it is.
if you remove the specks does it leave pits in the metal?
usually when exhaust valves look ghost white when cleaned it indicates too much timing / detonation
perhaps the same applies for sparkplugs
its weird i have never seen or heard of something like that
what plugs are you using?
i once had a 592whp ep on pump gas, i sold it and bought a Z
(heed my advice i know what im doing)
bkr9eix just like i was tuned on by st00pid. this is the first time i have seen this on my plugs, but i just started using murphy's usa gas (aka walmart gas) cuz they are the only ones that carry e10. i was tuned on e10 so i wanted to use it, but now im thinking of just going back to shell even though it isnt e10.
e10? 10% ethanol? whats the octane rating of that?
a 9 heat range? thats a bit over kill for anyhonda im running 7s
it could be a combo of deposits and too cold of a plug

Melted piston?Originally Posted by squeak04si
well you can ask anybody, that is the only plug st00pid will tune on. he has his reasons and i have never had a problem with the plugs for the past 2 years. its 93 oct e10 but i think the plugs may be normal. the car has been in open loop til up to about 2 months ago, then i switched it to closed loop. so im used to seeing the plugs a lil black. i guess im just being a bit paranoid.
i doubt that. the car still drives and during wot fine. i dont feel any power loss and i already checked my coolant level.
as a piston starts to melt it starts to pit really bad and slowly overtime
especially with oem cast pistons
reload you cal and select to have the CEL flash when it detects knock just to be sure cause detonations will errode a piston overtime

it has been set like that. i have only seen it flash maybe a few times in the last 2yrs.
