b16a 97'hatch-i decided to change my plugs because my engine didnt respond like when i got the swap. When i pulled all 4 spark plugs out each end was full of oil.
What can be causing this problem.Also, i here a clicking noise on the head and i dont know why it makes that noise. Do i need new piston rings or valves???
any help please

 

Could be your valve o-rings, that is cracked and is leaking. Blown headgasket or problems with pistons rings.

Do you see white-bluish smoke out of your exhaust?
