I just finished putting in my new engine which is a d16y7 block with d16y8 head. Motor has jackson blower on it. There is more but I don't think it pertains to my problems. I have a vacuum leak coming from the line off the black pcv box going into the intake manifold. Also the car has no power, meaning if I even touch the gas it sputters, misfires, and will not go. I'm also getting some smoke out of the exhaust which seems to be oil. Now I saw this motor run in the car it was in before mine and had no oil issues. However my last motor I crack two piston rings and was pushing a lot of oil out before I removed it, not sure if its left over oil in the exhaust or could somehow be caused by the pcv issue. I am running a Kenji Ecu if that makes any difference. Im sure I could be more helpful but for now this is the best way I can explain it. BTW this is the first motor I have tried to use this ecu on, my other was a stock ecu. Car will not even drive up a hill. Thanks for your time and patience reading this...Any help would be greatly appreciated.
