Default Spark plug question



This plug is out of my newly aquired Legacy Turbo. It looks like its in very rough shape. Where is all that oil from? I pulled it from the number 1 cylinder so its not oil that dripped down the filler tube. Could it be from a bad valve cover gasket? Or something more serious? What would cause scorching on the porcelin like that?

I've got a new set of iridiums that were in my WRX for 200 miles. Is it ok to replace it with these? I looked up how to decode a plug but there wasn't any info on the one I pulled out (BKR6E) All I know is that it physicly fits and its the right heat range.

i'm going to be doing plugs etc on my legacy turbo soon - we should meet up...

I wouldn't run iridiums in it - NGK BKR6E-11 work great...

Well i've got two sets of iridiums just sitting in the garage. I'm not going to go out and buy another set of plugs now.

A guy on the legacy boards said that it was a crack in the plug and that exhaust was coming through it.

Yeah....the insulator may have cracked....Also looks like somebodyu may have been lazy and not changed all 4 plugs the last time....
This is why if you ever drop a plug on the ground, its next stop is the FOD barrel and a new plug is used. The insulator can have a VERY fine crack that is almost impossible to see...so....get a new one and don't drop 'em
