Ok I need some help I am stumped. I have 93 accord lx it has the f22a1 and it is leaking oil into the spark plug holes which I know the solution to that. But it is also leaking underneath the car and I tried to take the best picture I could of where I think it is coming from. But i have no clue if it is even connected to oil. So here is the pic and please let me know what it is.

It is the part protruding from the block right above that black tube:

 

Going to need better pic(s)

 

Looks like the oil pressure switch......you can just see the brass hex, then the single wire with the boot over it.

 

if its that black plug above the filter that is the oil pressure switch. the black plastic part you see pulls right off the block and then a wrench can be used to remove the rest. never removed this before but im guessing there is an o ring keeping it sealed. its either loose or the o ring is bad. rtv sealant makes an oil resistant sealer that would work great

 

Have the same oil leak problem..Will check oil pressure switch..Hope it will be easy to replace...Thanks guys...

 

Yeah, looks like the oil pressure switch is leaking. On my H22, my oil cooler was leaking due to a bad o-ring.
