: oil leak at spark plug

So I was changing my fuel pump and while I was laying down there I noticed that there was a little path of oil coming out of the spark plug hole right above. I'm pretty sure that it isn't good but what does it mean? Like blown rings or something or is it the plug just not screwed in all the way. I haven't even done anything with it yet cause I wanted a break for a while. Its a 350, 4bbl edelbrock carb, 600 cfm, accel HEI, 2 1/4 in pipes, the heads aren't stock but I don't know what kind they are. thanks

Popbirch - take a look at the plug itself, if it's not extremely oil fouled, the problem may just be a slight leak from the valve cover gasket, and dripping down into the plug hole recess.

Could be a valve guide seal, although I've never had them leak so bad that the oil dripped out from around the spark plug. Usually the spark plug just oil fouls.
