so i brake clean valley and blew it out with air everything had oil on it any help would be great

thanks

 

The most common oil leak in the valley is from the HPOP hoses/fittings or the turbo pedestal. The EBPV can also be leaking. Now that you have cleaned it, you should be able to find it a little quicker.

You may also look at the valve cover on that side, could be loose and leaking, or the seals on the gasket are worn and leaking.
