I mean, that's a LOT of water to bend 5 piston rods!
I was not with him when he drowned it.. he called me to help him get it out of the water.
It was about 16-20" deep and 50 yards across. I am sure he hit the water going too fast and the wave came over the front getting sucked into the stock inlet at the top of the grill.

There was a 5" thunderstorm downpour and we use the streets for drainage in west Texas.. when you see a river where a street was.. TURN AROUND

Thanks. I tend to avoid puddles but this is just simply amazing.

I'm also amazed that the engine appeared to run afterward, as one of those pistons is so bent I can't imagine it traveling up and down without supreme friction.

Simply amazing. You're one of the FEW people here who can rebuild an engine. I'm impressed. That's why I tried to link this thread with as many relevant E39 threads as I could (same M54 engine).

thanks.

The bottom of #3 piston was hitting the balance lobe on the crank as it passed through the cycle it was so bad that it cracked the piston at the wrist pin bore.. (#3 was the only piston replaced) only 2 cylinders had decent compression.

Not only did it run but it had good power. I was really surprised to find so much damage inside... These are great engines

It's alive!!

Received the module yesterday and everything works perfectly. I took the car out to run through the break in.. WOW, I forgot how smooth and even the torque is on the 330... break in can be a lot of fun

I read the entire thread and just congrats)
You did it. Fixing something makes someone feel much better than simply replacing it.

Though I didn't understand how the stuck injector(s) burned up the DME
Why did the injectors get stuck at first try and then they worked properly after you put in a new DME?

Could you care to share a bit more info with us?

I really can't imagine how the injector relays were fried.. so for a moment I considered a stuck injector as a possible explaination but after thinking about it.. there is no way. Somehow that circuit grounded out and cooked #5 relay which in turn cooked #4 and #3 above it from the heat/fire.

I tested every part of the injector circuits twice before reinstalling the DME.. all is well now.
I always disconnect and reconnect the battery as the first and last step of any remove/replace.. considered the possibility that it happened when he hit the water but it still ran ok.. may have just lost #5 then and it cooked the other 2 upon restart

Thanks to all for the congrats, the most satisfying part of this project is the end result... a fresh engine in a sweeeet 330I 100% paid in full!

Nice looking car. Would have been shameful to crush it. Again, very impressed.

Thanks, I agree it would have been a shame to scrap it.

I still have some work to do.. it seems the water killed my idle control valve as well. I have a new Bosch oem unit on the way.

Also leaning toward new drilled rotors and ceramic pads... it could use them

Since the car has the premium pkg, sport pkg, 5 speed and new tires it may have been more than a shame to scrap it... it would have been a SIN!!
... or at least that's how I view it
