Second break... oil on spark plug threads
where as the first three had that anti- sleeze stuff this last one had engine oil on the threads... what does that mean? I remember when doing my lt1, someone said it was pretty bad for a car to have that... just dont remember what it means...
anyway... i plan to change em out once a year or so... so next year i'll hit it with the sleze
That one probably had oil on it because someone change the plugs before and skipped it because it was too hard to get to. i didnt get to those last two on the passenger side... but all the others were done... but she seems to rev better...
