I would double check a couple of things...

Valve cover seal...it may not be it, but check...feel the back of the head, closest to the firewall...if you feel any oil, you may have a leak.

Broken rocker arm....crazy, but it will cause overpressure because the valve is not opening, and start forcing the oil out in odd spots of least resistance.

Oil Pan seal...make sure it is good...it may just need to be tightened.

After that, you get into some of the major mechanicals and or rear seal issues.

Sorry about the leak. :-(

Thanks for all the suggestions. I am assuming the worst but hoping for the best. The more I think about it, the more I think it may be an intake or valve cover gasket leak. Any other options are not so good...

I have checked the calibration on my torque wrenches tonight and I plan on tightening everything up in the morning. One way or another, I will figure out where the oil is coming from tomorrow. The thing that has thrown me off is that the leak only occurs when I shut the engine down.

I will let you all know what I find out this weekend.

That would suggest it could be in the rear main or pan rail area. Pan is not nearly as full when the car is running. You shut it off, the pan fills up and oil comes out of the breach.

Most auto stores carry a dye kit that involves a small bottle of florescent dye, a penlight and yellow goggles, usually about $20. Dump the dye in the oil system, fire it up and watch for the pretty (ugly) neon green to appear.

Default Before going crazy lets--

Mongoose930 Jim been reading my threads. Elmaraichi has it right. Go and buy the leak finder kit with the dyes. Make sure you oil is full and run the car for a couple of minutes. use glasses and light to find leak and repair. This is right out of the manual. I don't understand why you have no leak with motor running and get a flood with motor off. You have good oil pressure with motor running?? If your car does have a PCV in it, there may be enough vacuum inside to keep the oil from leaking out and when motor is turned off, out comes the extra. I am thinking valve cover gasket leaking between intake manifold and head. Returns are slow. Do you have the tins under the rockers?? Get kit and you will fine out. Rick L. Ps Jim you have learned well, grasshopper.
