Make the bad noises go away! :whine:

[Critter]

I just rebuilt my transmission. Took me about a month to learn as I went! Finally put it back in the Blazer, filled up all the fluids, started it and immediatly heard a knocking noise. Thought it was the transmission All that work!!! Anyway, I slept on it and went out today to take a look at it. SOUNDS LIKE ITS THE MOTOR! The thing was sitting for about a month in my garage and ran fine when I parked it for the trans rebuild. Also, it looks like there is a fine mist of oil coming out of the passenger tail pipe, the same side as the sound (I think). It is a little deaper sounding that a lifter taping, so it has me a little worried thinking that its a pushrod or worse, connecting rod! Anyway, just thought I would share my grief.
