ive changed my spark plug tube seals in the valve cover twice..and the spark plug tubes eventaully fill up with oil...what do i have to replace? and how? the spark plug o ring?i had the problem in my old d series and had to take off the rocker arms but is it the same process for b series and dohc's? i have a
b18b motor and not sure what else i need to check/replace. any helps appreciated

 

Spark plug seals should do it. Try some hondabond on them...and make sure to tighten your bolts down and that your valve cover gasket is properly seated (if it isnt then the tube seals wont be flush).

 

this happened to me once too after i had the VC off. I forgot to torque to spec. re-tightened by the book and all was ok
