Driving the car yesterday i peeled out from a dead stop and and half way through lost acceleration. The car was still revving but not moving and started to smoke. I pulled over and cut the car off and looked underneath and between the motor and transmission was fluid running down and oil coming up through the intake bolt holes. Waited 3-5 minutes and limped to my mothers waited a while longer and drove home. The ride home had no UMPF acceleration was terrible and it took a while to pick up speed. Also fuel pressure dropped to 39, its usually 40-50. The fluid was a dark orange/brown but doesn't look like its dripping from the transmission it looks like a little of the lower rear main seal is sticking out and thats where its coming from. I ended up adding less then a qrt of oil to the motor and got up to 45lbs oil press. I'm getting ready now to crawl back underneath and try to find the problem exactly. Anyone ever had this happen before? Could i have over filled the transmission and boiled too much fluid out of it?
rear main or transmission issue?

Usually if you overfill an automatic transmission it will blow the fluid out of the vent, typically located on or near the top of the transmission housing. If the vent is plugged, it might eject the fluid past the front pump seal or even out the dipstick tube. Some dipstick tubes these days have the mechanical stopper like a thermos lid, trans oil is going to be really active to expel past that. A good telltale sign is if the pan gasket is saturated as if fluid is trying to leave the premisis. Might be a little difficult to tell with as much of a leak as you appear to have.
What doesn't make sense to me is why the thing would lay down? Low fluid would cause it to lay down but typically not over full. I don't really get the comment about oil coming out of the intake bolt holes? That would mean there's excessive internal crankcase pressure. You didn't install valve covers with no breathers right? What about the PCV valve and hose. Should no way be that kind of crankcase pressure. If there is, oil is going to come out everywhere until there isn't. ...

from the looks of things i figured it must be the rear gasket on the oil pan has pushed out some. Theres the smalles piece that sticks out only a little, thats the only thing i could come up with that makes sense.
ssbrewskyaz I do have a valve cover breather and pcv. Although since then i cut into my heater box to take pressure off of the pcv valve.
I'm having a session while writting this so bear with me..........But what would happen if my motor jerked the pcv valve into the heater core box making it loose its seal? Would that cause too much crank case pressure?

Sure sounds like you blew your head gaskets. When you do, it feels like someone slammed on the brakes.
Sounds like compression is getting into your crank case and blowing oil out. The intake bolt holes are not blind, so its possible for the oil to seep through the holes. If oil is pushing up through your threads, we're talking some serious pressure here. Most likely, you blew the intake seal at the back of the intake, and oil is running down the back and dripping near the trans/engine mating.
Pull your spark plugs and see if you have coolant/water on them. Do a compression test. See what you find.
Just because the oil is running down at that location doesn't mean the issue is in that area. Its the most common place for oil/fluid to leak down from, because the engine is tilted back, and everything kind of collects in that spot and drips down. The actual source may be from much higher up.

I'm so pissed off today. Last night I ended up tearing down the transmission and found the only thing wrong was the gear on the input shaft where the converter sits had a chunk taken out of the two notches on either side. All gears, clutches, pump, valve body were in good shape. When i dropped the transmission pan i found metal shavings. Poured fluid out of the converter and found metal shavings also. I figured my whole setup has maybe 100miles but i bought the converter years ago so no warranty. So i took it to a builder who opened it up and this is what i found.
