sparkplugs cover in oil

[jlm_62]

I have a 99 eclipse 420a engine I have to replace sparkplugs every month everytime I change them cylinders 2,3,4 are covered in oil. I can put new plugs in take them back out without cranking engine and they will be covered in oil ran a compression check today cylinders 1,2,3, all at 175 cylinder 4 180 Im thinking the valve seals might be bad.
the engine does use oil and smoke out exhaust oil pressure 50
Im planning on putting a crower stage two cam in soon and have some head work done I was planning on rebuilting the whole engine but if the shortblock good I may just have head work done. ANY IDEALS on whats causing oil to get on plugs also is that good compression numbers for this engine.

I'm not sure what the compression should be on the 420a but I can tell you that either you need to replace some seals or your rings are shot. I'm gonna go with seals though since your compression is still that high.
