O.K. guys I give up I am about 5 seconds short of just selling this car to a junk yard. I dont know what else to do. I have oil getting into my manifold. I dont know from where though. I checked the pcv line and it is dry as can be. The hose from the vacum tree to the back of the manifold has oil in it though. Everytime I pull it off the back of the manifold it fhas oil that comes dripping out. This is a Edelbrock 5.0 performer intake and manifold. When I pull the front cover off the manifold it is always got oil laying in it. Every runner inside it has oil in it. Ihope this is what is also causing my blowby. When I start it up it has some blue smoke and if a get on it hard it has some that shoots out also. I have done compression test and every cylinder is at 150 except cylinder 4 is at 143 and these numbers dont change with or without oil. I have done a leak down test and the leakage needle on the leakage guage didn't budge off zero. I am clueless and fed up. This motor was just rebuilt and the thing seems like it has more issues now than it did before I had the lower end and heads redone. Something else I dont know if this could be causing any problems or not but the hose that goes from the vacum tree to the back of the manifold doesn't have a hose clamp on it where it slides onto the tube coming off the manifold. Should it have one or not.
