I have a 95 B18B in my 93 Honda del Sol. I have had problems with oil leaking in to the spark plug cylinders ever since the swap. I have replaced the valve cover gasket and o-rings twice with no change. Also re-torqued the valve cover and replaced the cap nut washers. Warped valve cover? Any other ideas? I can't "read" my plugs because they are soaked in oil from above every time I pull them.

 

is there oil only on the top of the plugs, or on the electrodes as well. if the latter, you might want to do a compression/leakdown test to rule out some bad rings.

 

Oil only on the top. Compression test/leak down done right after swap. 200 lbs all cylinders. Leak down cylinders 1&2:5%, 3:4% 4:6%.

 

try some hondabond, or silicone around the o-rings. mine did this, but it stopped after I swapped seals.....how tight are you tourqueing down the valve cover?

 

Torqued to specs:8ft-lbs

 

hmmm....well I'm out.....try some honda bond.....other than that.....anyone else got an idea?
