SO I Purchased A 87 Grand National Last Saturday, I Drove It Fot A Day Or two No Sign Of Leaking Oil. But All Of A Sudden Its Pouring Out Oil. It Wont Leak Oil Sittin There, But As Soon As I Go Down The Road And Come Back Its pouring out. It Looks Like Its Dripping Down The Timing Cover To The Left Of The Harmonic Balnancer. The Previous Owner Said He Had A Front Seal And Timing Chain installed. Can Someone Please Give Me An Idea Of What Mite Be Leaking. The Car Runs Great And Is In Awesome Original Condition. Just Gotta Figure This Out So I Can DRive It Lol.. thanks

Sounds like the timing cover gasket is torn or broke somewhere , most likely the gasket may have slipped when doing the timing chains , you can check all the bolts in the cover to see see if any is loose or missing . If that does not work r&r the cover and replace the gasket .

Could be anything. Get some dye and a black light and find the leak.

Clean it with some engine degreaser and a hose.
Spray foot powder on the area - and start he car.
Foot powder spray is $1 per can at Dollar Tree.
Certainly sounds like an oil "pressure" leak - but it could be a seal or a gasket.
Wouldn't think you need to drive it down the road to find where it is leaking.
Look carefully to the left of the harmonic balancer, - and up under the turbo. On the block.
That is where the oil pressure sending unit is located, the hoses, the "T", fitting, and hard lines are often hacked if someone added some gauges or whatever.

Last Night I Sprayed It With Engine Degreaser And I Found Out Tbat It WasPouring Down The Timing Cover. At First I Thought It Was TheaAdapter For The Oil Cooler Between The Filter But Thats Not It. Tommorow After Work I Plan On taking Out The Intercooler And Get The Harmonic Balncer Off So I Can Get A Better look

And that's such a fun place to work in - and such a fun part to take loose. They're downright evil.
There is supposed to be a bolt there. Pop one of the bolts out of the fuel pump block off plate. The missing fastener is the same size.
I also see you have one of those oil pump spacer plates. There's a chance you have a leak there too.
Keep your eyes open with the car. With the level of attention that was applied to the timing chain/cover/pump job, there might be other stuff waiting to crop up.
Do you have a front mount intercoler on the car? I see a non stock bottom bolt holding the wiring on and no intercooler bracket there.

Last night I couldn't keep my eyes open, while others are like Owls
Yes, there should be a short bolt as I indicated in the photo I provided for you.
I don't know off hand what size is that bolt, and maybe someone can chime in and tell you the exact bolt size.
