Spark plug tubes seep oil at valve cover, fix please

Spark plug tubes seep oil around the top at the valve cover after each run. Anyone have a solution?

Check the orings in the valve covers?

 

?

Too much pan pressure? aka blowby. make sure the orings are good.

 

Tubes

Guys let me clarify. The seepage is at the top of the tube where it passes thru the valve cover, not down at the o ring in the head. I have an o ring there now but it is not adequate. Any suggestions?

Thanks,

o rings

One in the head for a single plug head, and one where the tube top registers at the valve cover. what diameter of the chord do you have now ? the size of the ring might be too small, but i have seen these o rings real compressed out and they do not pour oil out, do you have good boost ? you might be leaking boost into the valley

 

We have a o ring in the head and also on the tube.just slipped on the tube at the top were it hits the head receiver for the tube...never any oil leaking....
