Explained: Changing Valve Cover Seals (O ring seals)

[NickJr.]

Hope this is the spot for it. Narend I know I took long since you asked me about it, but here it is.

I changed the seals on the D15B of a 91 Civic and I took some pics during the process so I will give a little run down as to what I did.
First off I must thank Inshan and X2 for the run down on what to do, and Yeo for use of his tools (spark plug socket and rachet).





These two pics show the engine before the work starts you can see where some oil was leaking out of the 3rd tube.





Well these pictures speak for themselves after removing the wires some more oil poured out of them. Also I detached the accelerator cable from the valve cover, followed by the ground wires (not pictured)





After removing the bolts and grommets the valve cover popped off fairly easily. Had to pull the accelerator cable out of the way to get it off completly. N.B. remember to disconnect the breather from the valve cover to the air filter.
You can see where the 3rd seal was bad and was seeping oil into the tube





A closer look at the oil in the 3rd tube.





Well these show how much oil was down in the tube, at first I thought it might of spilled over. You can also see big particles of whatever in the oil



The seal kit from FelPro, you can see the grommets and the valve tube seals in the bag.



The shaded area shows the seals and I pointed out the bad seal which is covered in oil.





Cleaned out the tubes and the seal seats with some gumsolve, also cleaned off the area where the valve cover seal sits on the engine.





I cleaned off the valve cover and put in the new seals, reconnected the accelerator cable and ground wire to the cover (need to change that) On the half moon of the cover I placed a bead of silicone as instructed by Inshan before placing the cover back on and tightened the bolts down, being careful not to over tighen them.



The new NGK's just before I put them into their new home







The new wires are put in place and the engine bay given a wipe down.

I hope this helps anyone who might want to do this, it's pretty straight forward as I was told, and after starting it up and buring out the oil that went down into the combustion chamber the engine was running smoothly and starts in one go and it no longer misses.
