Oil coming out by spark plug???? help!

tighten your spark plug, could be the plug or head is stripped too...

plug is brand new, pretty sure the head isnt stripped, its a pro design cool head. Maybe i just need to get the plug good and tight?

Dang, man. I don't think they need to be too tight... Make sure you tightened the plug enough to compress the compression ring though. If you got to a point where it snugged up after that it's probably tight enough. For all the spark plugs I've used i've never had the problem you're having.

if its a new plug, you do have to tighten it quite a bit to compress the ring. it will feel like its getting snug for a while.

Your running to much oil in the gas... If your at 32:1 go to 40:1.

and you will be fine..

I've seen this with my cool head also. When I buy plugs now I pre gap them and run them on a stock head to compress that ring then box them back up. I've noticed they will tighten quit a bit on the cool head before that ring compresses so thats why I do it when I gap them. I don't want to change a plug right before a race or a moto and then have it cost me a race if its not tight enuff.

it wont matter how rich he is. if hes blowing fuel through the plug area, hes sucking air through there as well. if you were blowing oil out a head gasket, would you just lean out your fuel mixture? this is no different.
