Okay I just got back from my second mechanic. He told me that the Power steering Pump is indeed leaking but could not spot any other leaks. I mentioned the slow leak I had possibly by the rear main seal. He could not spot the leak initially but I told him I cleaned up all around the engine and oil pan. He wanted to save me some money and told me to use Bars Rear Main Seal Leak. I then went to auto zone and purchased the product and put it in my oil as directed.
But even after I cleaned my engine, pump and chassis around the Power Steering Pump Bone Dry, It got soaked with fluid again and my mechanic confirmed that he spotted the leak in the reservoir itself. Furthermore the reason why my PS pump kept making noise after so long is because the crack brought air into the pump thus making the noise. Once I get the new pump as it is covered under warranty, I will bring it to my mechanic and he will install it for me. Regarding the rear main seal leak, he told me that most likely the Bars Product will seal up the leak as it is very small.
