Hey everyone. I've got a question on an oil leak on my '96 Formula. The oil leak started one day out of the blue, and it appeared to be coming from the front of the engine. I never did find out exactly where it was coming from. It was bad enough that I needed to carry oil with me, or stop at a gas station to buy oil by the quart (about a quart a week). It was my daily driver at the time, and I just didn't have time to T/S it at the time. 
Anyway, one day at the gas station, early in the morning (dark), while adding a quart of oil, I ended up dropping the oil fill cap, and of course it hung up deep in the engine bay. I couldn't see it, and I had no flashlight, so I just drove to work. And of course, it fell out on the way to work. Just my luck. BUT, after that, not another drop of oil leaked from the engine again! I drove it like that for about another 6 months before I ended up parking the car, and never dug deeper. I got the car out of storage and I'm working on the car again, and did replace the PCV valve and hose to the valve (it was melted with a hole in it). I found it because it was causing a noise with the engine running and the hood up.
Finally, my question: could a faulty PCV system pressurize the engine enough to cause an oil leak, or am I in for another oil leak when I get a replacement oil cap? Also, exactly what gasket could be leaking oil from the front of the engine? Crankshaft seal? Front oil pan seal? Anything else?
Thanks.
