I checked my air filter and spark plugs(# 1, 2 and 6) , air filter is pretty dirty but the worst parts is my spark plugs!
Here is the picture, god, oil is full around the spark plugs......
Anybody know why? Any good ideas? Do I have to replace all the spark plugs?( I wish not, I don't want move the intake again....)

Hi!
Your oily plugs are due to leaking oil gallery (14mm hex drive ) plugs , mine did this too! the rubber o-ring under the plugs had carbonised and cracked causing the slow leak by pressure/gravity into the adjoining plug hole.They are VERY TIGHT - take care when trying to remove -I used a 1/2 inch drive power bar and a good quality 14mm hex drive and short extension- could have done with some help to hold the extension straight - -you will need some new o-rings to cure the leaks , also a good idea to change the cam cover gaskets, I also changed the clamping screws for 6mm (10mm hex drive ) bolts to get a better clamp-up - no leaks now!
