I finally got my truck going and now the old girls blowing oil out the front thinking it's the crank seal but not 100% what I'd all need for gaskets and seals to replace it here's some pictures of the mess lol

From your pictures it looks more like the oil pan is leaking and not the front seal. Usually when the seal is leaking the balancer is also covered in oil, your's looks dry.

Luckily on a four wheel drive you can remove the pan without lifting or pulling the engine .

If top is dry [valve covers, intake, oil sender] then go to front oil seal and main seal. You don't say what year and engine. Assume it's a 79 K10. Have seen oil filters leak at the crimp, check that first. Otherwise, at the very least you will need a main seal and pan gasket. Possibly an oil pump and screen. Top cap of rear bearing needs to come off for access to seal.

edit, do yourself a favor and buy a 1 piece pan gasket. Thay are expensive but dealing with a 4-piece gasket in the vehicle is a pain.

Also pressure washing and getting everything clean really helps to spot the leaks. You need to take a lot more things apart to change the front seal, and if it isn't leaking now, that is time and money wasted.

It is coming from right under neith the Balancer I'm pretty sure up top is dry I did the valve cover gaskets already underneath the Balancer there is alot of gasket maker the pan and every thing else was dry till I took it for a good drive today I just changed out the clutch I could drop the oil and pan make it all nice again and see if it still leaks I suppose but it dose look like it's coming from the bottom of the Balancer that's why I'm wondering if I should pull it any ways to find out I'm kinda trying to make it my daily winter driver
