Hi all, I can use some advise for my D16Z5 engine (in a CR-X ED9). There's a fair amount of oil sweating on two places: - the (outer) valve cover sealing - the sealings (O-rings) in the middle of the valve cover I bought brand new, Honda original sealings. cleaned everything well, did a small amount of engine oil on the rubbers, tightened to specified torque.... But the oil is still coming through the O-rings around the spark plugs (on all 4, just like before). When changing the rings and spark plugs there was already a fair amount of oil around the plugs, but it will definitely come again. The old ones definitely needed changing as they became hard and brittle. My question: is it a good idea to add a little (!) liquid gasket on the O-rings of the spark tubes? On the picture attached you have an idea of the amount of oil that leaked into the tubes (with the old O-rings). My spark plug key is covered all over in the oil, as is the spark plug. Thanks for any advice or ideas.
