My x5 hydrolocked and broke a rod, now what

[90turbo1]

So the X5 that I have been driving for a year now finally gave its last f-you to me on sat.

its a 2001 4.4 224k on body, a low mileage 61k motor was installed due to previous timing chain breaking. Motor was done by me, all new gaskets, and CCV parts through BMW. Motor had a 6 mos warranty on it.

well about 4 weeks ago the CCV froze and car started to burn oil and smoke badly. we towed it to my shop (bmw shop I am a tech for) and i went through checking the CCV system I found massive amounts of water and oil goop coming from rear intake cover, the funnel thing also had goop in it. I cleaned and replaced the rear cover for intake, removed intake and drained the oil from it as well. reassembled and added the heated wrap mod to the upper hoses accross the intake. took it for a drive and it drove great. that was the first cold spell we had about 8 deg. Now flash forward to sat it was 10 deg again and snowing blowing. we started car in drive way let idle for 5 min and then drove to store. We drove about 10 min max, as I went to back into a parking spot (so we can load the hatch without wind bloing at us) the second I started to move in reverse the motor made a chug, chug and stoped. Starter just clicks.

I had a friend give me a ride home to get truck and I drove back and tried to jump start it. no go.

towed to dealership. I removed all plugs and found #1 full of oil, #4 full of oil and also oil on #8 plug. all others looked ok. hoses were froze again. even with heated wrap they froze. tried to turn motor over with breaker bar and socket and it would not move. I turned it backwards slightly and it started to move. I then was able to bar motor over clock wise again about two revolutions and it would stop again. looking in the spark plug holes I could see number one piston does not move. #4 does move which share a journal so crank did not break, it has to be the connecting rod.

so, my best assumption was that oil started to pool in the bottom of the intake. when I put in reverse and started to back up it must have caused it to run to the front two runners and lock the motor up. Damn poor design if you ask me. If I were out beating the hell out of it I would not be so mad but i simply put car in reverse and started to move and bang...

I think I am done with BMW v8 motors.
