I just got through replacing the knock sensor on my 2000 VG33e and after I put everything back together and filled the radiator, coolant started leaking from the intake manifold. The coolant is coming out of the throttle body opening and there's a stream coming down between the engine and transmission. It leaks about 1 cup a minute. I took pictures before I did the job and everything seems to be hooked up right. Somewhere coolant is dumping directly into the intake manifold and what doesn't go into the manifold drips down onto the engine. This is not a throttle body leak. Any help would really be appreciated otherwise I'm going to have to take off the upper manifold again to try and find the problem and that's a real PITA!
