need help new to this - oil leaks and possible clutch slipping

[sliploose]

Hello all. My name is Jeff. Nice to meet everyone. I am very very new to nissans and turbo cars. Please don't make too much fun of me. lol...Anyways...I need some advice. I recently purchased a 1993 Nissan 240sx with a sr20det motor. Its got a turbo...woohoo..my first turbo car! I am pretty excited. the motor seems to be in fantastic shape...very clean...recently rebuilt from top to bottom as told to me buy the guy I bought it from. I drove it for about three days...I put maybe 200 miles on it driving back and forth from Lumberton to fayetville nc about three times and taking it to Walmart and back a couple times. So after having it for about 5 days I was poking around looking at the motor and realized it was leaking a little fluid. I couldn't tell if it was oil or transmission fluid but I could see a little drip coming from the bell housing which scared the poop out of me. So...I am no mechanic..although I learn fast and am quite capable...I knew this was a little beyond me. I saw absolutely no leaks anywhere on the motor itself so I was pretty confident I didn't blow anything...I didn't beat on the car really at all. anyways...today I took the car to a mechanic and they got it on the lift and after a bunch of trying to figure out where this leak was coming from they finally figured out the screws on my greddy oil pan were stripped and oil was seeping out of the back of the pan. this was blowing oil all throughout the underside of the car. there is a tiny little plate on the front of the transmission and apparently it isn't sealed...its for inspecting the flywheel is what they told me...nice guys btw...they let me stay under the car with them the whole time. I learned a lot...so what was apparently happening was that little bit of oil was filling up inside the transmission and dripping out that little seepage hole right there on the bottom of the housing where the trans meets the block...great..transmission isn't bad..
as soon as I left the shop about three or 4 miles down the road my car started feeling like it wanted to stall. I would press on the gas and almost nothing happened...the motor would rev but the car took forever to come up to speed and it was sputtering and popping the whole time...WTF IS GOING ON! how did it run perfectly to the shop...on the dye drive...and then all of the sudden want to cut out and not come to speed....what could be causing this? a bad clutch? does a bad clutch cause the car to rev and not come to speed? I am at a loss cause I have already spent too much on this car...lol. I love it but I need to know where to start and what parts to start looking up...I smelled clutch the first few times I drove the car and also smelled gas too...there is also a fuel pump primer switch I have to turn on to start the car....it almost feels like the car isn't getting enough gas when I hit the pedal...it just takes forever to come to speed and its like its fighting itself...fuel pump? clutch? entire transmission? any help would be greatly appreciated...sorry for the long a** post and ill try to keep the rest much smaller...thank you everyone.

Hello there it sounds like your Rear Main Seal is leaking, and yes your car will not run right if it is leaking between the transmission and engine block. This would be in the area where your clutch and flywheel are at. While the transmission is off the car when you get it fixed, you might as well get a new clutch and resurface flywheel if needed.

Not sure what's up with the popping like you mentioned, unless you have a boost leak or vacuum leak somewhere, but yes, the engine revving and the car not going anywhere is typically indicative of a clutch slipping... which happens when your flywheel or clutch gets oil on them either from the rear main seal leakage, or other area.
