Oil Pressure problem... Suspecting Turbo issue

[Parmas]

First of all I am suspecting on turbo because I am seeing sostantial amount of oil at the compressor outlet ( the outlet that goes to the intercooler piping to the engine). If I clean the oil and rev the engine while idle till 4K rpm no oil seem to spit. If I go for a street run and push it on boost I will see oil traces into the compressor outlet.

I bought an oil pressure gauge and fitted temporarly between the oil IN of the turbo and the turbo fitting itself. Started the engine and got 15psi increasing to a stop at 40psi (Please note the engine and oil are cold). Throttle up the gas till 4K will give me about 3 psi more making 43psi. I let the engine idle and the pressure slowly decreases to 19 psi. I didn't let the engine more idle to check if it goes lower to protect it.

I am suspecting that when the turbo is heating up, it is causing a slow leak. The more the turbo heats up the higher the leak and the lower the pressure goes.

I made a video for you to review.... Note the slow pressure increase? Is this normal increasing that slowly or not?

Btw I am using Torco SR1 10/40 oil, compatable with turbo chargers. http://www.torcousa.com/torco_product/sr-1.html
