Looks pretty wierd to me. Right beside the starter. Any ideas? The VW dealer got authorization to tear into it today. It is in a 2001 1.8.

Yes, VW is tearing it apart on their dime. Assuming it was a rod that snapped, wouldnt that have made a terrible noise. I didnt hear a thing and the car was still running smoothly for the few minutes after the smoke first appeared. I did notice a loss of power.

Looks like it was a casting flaw in the engine block. Basically a "bubble" of air when the block was cast. Looks like it finally just blew out.

You're lucky VW is picking up the dime on this one.

As of right now, they are only picking up the dime to tear the motor apart to see whats going on. No decision yet on the new motor, but I am working on that:lol:

Exactly my thoughts, and I look at a lot of metal parts. How weird is that, VW castings are usually very well-made.

I called the dealer this afternoon to get the scoop on the tear down and the service advisor told me that the rod caused the hole. I then asked if the rod broke, a bearing gave loose, or what? She said, "oh, we didn't take the engine apart." Turns out the dealer did not tear into the engine but rather put it back on the lift and had the Shop Foreman to give his opinion. But I was told the Shop Foreman had been working on VW's since he was a kid and that he knew his stuff, so that was sufficient!!

If it's a void, clean it out extremely well and fill it with a metal filled epoxy. It's not carrying any load, just holding the oil in the sump. Silicone may even work. You might want to take a dremel with a rasp bit to it to get a fresh surface.

As far as a thrown rod, turn the key and shut it off as soon as it fires. You'll know right away if it has a thrown rod. A fraction of a second of dry run won't hurt. These engines are tight and hold oil a long time.

What about that dorky guy as the VW salesman? That was a casting flaw if I ever saw one...

:whistle:
Actually, I thought that was type casting. :)

it doesn't really matter, so long as they're willing to cover the engine replacement.

The engine was running with the hole in it and there was zero noise. I pulled it right into the dealer bay area! Thats why I questioned their assumption of a rod.
