camry 89 2.0 4 cyl OIL LEAK!

i have a camry 89 that has a bad oil leak. It only leaks when the engine is running and for about 5 mins after its off. I had the valve gasket replaced already, but it is still leaking. Can anyone tell me what they think it might be? and maybe how hard of a job (and estimate of $$) it would be? Thanx.

You could check the oil pressure switch.Not sure where it is on your car,but just look for a sensor screwed into the engine with an electrical connector on it,and see if there is an oil trail.

Where exactly is it leaking from? Bottom? Top? Left? Right? Front? Back? Give us a clue. If you don't know, make a point of figuring it out or have someone figure it out for you.
