Hey guys, I had some parts I needed (control arm & knee assembly) arrive today, so I brought my Z to the shop this afternoon and had the work done. I drove it home and parked it in garage. Didn't notice anything. A little while ago I went to go for a drive, started car and realized I forgot something in house so ran inside. When I came back out is when I noticed a very audible hissing noise. Popped the hood and it seems to be coming from the passenger side rear of the engine. Couldn't find any leaks, but it was getting dark so will have to take a better look tomorrow. But it is quite a loud hissing/leaking noise. This is only when the car is running. Nothing when just turning the key to accessory power. The hissing stops within a second or 2 of turning the car off. I drove around the block and got on the gas a couple times... it seems to run fine and spools up normal, but does give out a funnier/higher pitched noise once I hit 14 PSI.
