I built a DIY turbo kit for my Z28 and tested it out last night. Things were going ok until oil started pouring down around the bell housing. I only drove it for about 5 minutes, and I only let it go to 5psi. I took the turbo off and ran it NA for a few minutes. There are still a few drips coming down from the top of the back of the engine around the bell housing. Did I blow a seal or something? And at only 5psi?
