Insane oil leak PLEASE HELLLPPP!!

IMG_3459[1].jpgG'day all

New member and first time poster, In my garage right now I have a 12/91 Twin turbo GTO which I have to fix. I have got it running after it had sat for about 5 years due to a brother (the owner) who didn't look after his car. It had a lifter stick and was making a hell of a knock (have video proof of this) and now that I have solved this issue when i start it and let it run it leaks oil down the transfer case and all over my precious shed floor. This is not acceptable. I will upload some photos from my phone to show.

Now I have no idea where the leak is coming from. It has to be something pressurized due to the amount of oil that comes out. I considered the fact that it may be a crank oil seal but then I thought even that wouldn't drop this much oil. I even thought maybe a turbo feed line but alas not it either. because of how cramped it is in the engine bay I just cant see where it comes from. I am about to remove the inlet manifold so I can do a full compression test too.

Turbos on it are pretty average too they are in dire need of an overhaul, Luckily I have 2 spare (roughly) TD04 turbos which I can test with.

I would truly appreciate any advice given!

Thank you all!

From your new mate down under.


Edit: I will have to get photos later, I have stupidly deleted them!
