    That motor is pretty bullet proof but like the others said you never know. Plus the wife is supporting it nice move, well played.

    It drove great, but if it sits and idles...The slap sound starts. I'm uploading a video I took of it right after I got home. If you pull the wire off the thingy at the throttle body it should die (in theory) but doesn't. Revs high then low, slaps (knocks) then repeats the rev cycle.

    My son found out and wants it too. This is going to turn into a family rig...This is going to be fun. (y)

    I want to keep this thread open, but will move it to Quitters or Off Topic.

    Maybe I'm being too optimistic? :whistle:

    This video isn't doing the rev thing...Just knocking. :worry:

    Thats a bearing seizing. Look at the A/C compressor. I bet its something on the front of the engine

    ^That was my first thought too.

    If it's in the rear, check the torque converter. That is way too loud and random to be internal. I'd bet the engine is fine.

    A friend of my wife's has a Nissan crossover SUV thing that was making that same noise. It was the AC compressor.

    If that's all it is, you scored big time.
