Hey, guys what's the CAUSE...

of oil on one,two,maybe 3 even on ALL 4 wire-SET Plugs?

well, I kinda know but..I still have some mystery over this...I do know..that it's cause the block gasket is all burn,ripped etc. in other words it needs to be replaced with a new gasket pretty easy task taking off the vavle cover, taking off the old one, clean it out, putting on the new one then putting it all back together of course with new spark plugs and wire-set...with a fresh pcv vavle,oil change/filter...and ur done ..and well my REAL question is...what's the cause of this? how to proven it..etc.

oh and how bad is it on your engine running the car this way?

are you buring oil?

NO...but I'm just asking since I c this a lot on many used Preludes..
