I thought my turbo was going out and that I had an oil leak through the exhaust housing. But unfortunately I opened the hood today and looked on the driver side and noticed oil everywhere. I can oil think of a few things that could go.... Oil sender and the lines off of the oil cooler. This seems to be getting worse. Just curious if it is the hoses off of the cooler where can i get them and if i can't what can i use for the oil lines?

The hoses coming off the oil cooler are strictly coolant. They are not the cause of your oil leak. Possible soureces on that side are the OP sending unit, the oil supply line or the manifold that the sending unit and the supply line connect into. Also there is the dipstick tube loose in the block, the oil cooler could be loose,
valve cover gasket.

You might also want to make sure that your dipstick is seated properly in the tube. I've had mine blow out just a bit under boost and set a bit of oily spray all over the wiring harnesses on the driver's side of my engine bay.

Take a look in the right rear corner,right in front of the firewall in between the head and block.I had a BAD leak in the same place as you for a while.Well,after a new oil sender and manifold,a new oil supply line and a $35 rubber valve cover gasket...it still leaked.It was coming out of my headgasket.It wasn't blown through to the coolant passage or the cylinder,just through the back corner to the oil passage.Holy cow did it leak...of course,only when running.Give it a look see and let us know what you find.

I think I will try the valve cover idea and try to replace that seal maybe it is just that. I don't think it is the head gasket only cause the fact that the engine was rebuilt awhile ago. Any way to tell that it is the head gasket without taking the whole thing apart?

would i notice anything on the oil gauge if it was the head cause the gauge seems to fluctuate sometimes.....would that mean most likely a bad sending unit

Blast the whole area clean with brake cleaner, then start/drive the car, and use a good, bright light to see where the oil is leaking from.
