So, for several years i knew the car had a small oil leak somewhere. i would find oil spray on the underside of the engine, but the car never consumed oil between changes and i do check the level regularly and often. the last couple months the car has been eating about a quart of oil between changes and aproximately every 1,500 miles my air filter gets so oil fouled that i gotta take the whole assembly off and clean and drain oil out of everything, air box, tubes, a little trail of oil was even inside the lip of the throttle body this time!
i've changed the pcv valve, tried some oil stop leak (it helped somewhat but the problem didnt dissapear), and i've been dilligent about regular maintainance to my car. aside from a complete engine teardown (which i'd have to have a mechanic do as i cant realistically do myself

) does anyone have any ideas/suggestions on where this oil is leaking from and how i can fix it?
i'm running a 2.3L non turbo 92 with the 8 plugs and all stock, i even still have the air silencer because
when i went to take it off is when i first noticed the oil in there. the oil has been biulding up behind the silencer (which seems to be helping keep it out of my filter) so i've been reluctant to take it off til after i get this prob fixed. and if it makes any difference, the portion of the air filter that is closest to the front bumper is always the part that gets drenched.
any help on this would be terriffic.
