b16a leaking oil everywhere

my b16a1 has been leaking oil for awhile now. First i thought that it was the oil pan gasket, but i changed that and it still leaks oil, it seems to be coming from where the tranny meets with the engine near the fly wheel, someone told me that it was the rear main seal, but i i dont know, and also my spark plugs have oil in them when i took them out, could these be the valve seals? And then it seems to be leaking oil also around my vtec solinoid. is there anyone that knows exactly what seals i have to change so that i dont change the wrong ones??? help will be really appreciated

Could be rear main or even distrib. o-ring.

What part of your spark plugs have oil? Under threaded part or on top? If it's on top there are 2 seals per spark plug tube. The top ones are the most commonly changed with valve cover gasket, they fit into the valve cover. The second seal is between the tube 1/2's, in order to replace those you must pull off the rocker assy. Good time to do a valve adjustment. If the bottom is covered in oil you have internal engine damage, rings, valves, etc.

it has oil in the thread of the sparkplugs
thanks
