I don't think you can get help from the board.
Your car needs to have the engine opened up and evaluated. Probably the timing is off now as well. So you will need a shop with the right knowledge and the right tools. It's not only timing that's involved. Also, if the economics are in favor of rebuilding the engine, you might want to also change the rail guides and the tensioner (maybe this was the primary cause, as anecdotal evidence points at it as the main culprit for the v8's).

Sorry to hear about this.

doru thank you for writting, the situation is as follows: i towed it too a mechanic, he opened the chain covers, and the chain guides are f...ed (there is no rubber or plastic left there), the primary sprocket on the 1-4 cylinder camshaft needs changed, the chain also needs to go, tensioner as well...
The thing is that we are not sure if any of the valves are bent in there, because this hapened while engine was running...
I see you know your way arround v8's, i know nothing about them so any hint and advice is more then aprecciated...

Not a good story, very sorry. I can only echo what doru said. I'd suggest:

- Find a good specialist BMW mechanic that you trust (this may be the current one you are using).
- Chances are that there's some internal engine damage so you need an expert to open it up and give an honest opinion whether or not the engine can be repaired within your budget
- Go back to the seller if appropriate (unless this was an auction or "as is" purchase). If the guides let go after only 7km, it's possible that the seller knew the situation ahead of the sale. In any event it's worth checking your options.

Sad to say, there doesn't seem to be an easy solution to your problem.

I am no v8 specialist. I know only a few things as an amateur and helped a friend of mine tear and rebuild his engine which is similar to the 540. His is an X5 (4.4).

Chances are if the engine turned, the valves are bent.
Not sure where you're from. If in the US, I would strongly take a hard look at a "new" rebuild engine, in case you want to keep the car. It's less expensive than rebuilding yours. If you're located anywhere else, I have no idea what the labor market is, or how hard/easy it is to source parts and a good indy. This is avery hard advice to give. It depends how "clean" the rest of the car is and how "healthy" the tranny, front & rear end, etc is. The cosmetic part should also be considered. Also, if the car has any rust, just cut the losses. A pristine body can house another engine, I wouldn't do it the other way around (rusty body, good engine).

Well i would hate too lose this car couse it's in a good shape, and i think that this engine is more or less destroyed, but i would love too give it a try and open it up myself.
Anyway this would hapen only after i find another good engine too mount it into my car.
I was able to find an engine of a 1998 730i 3.0l v8 for like 600$ but since my car is 3.5l v8 i'm still having second thought's about this engine, so does anyone has some ideas about this???

That motor would probably bolt right up and more than likely you could use your intake and throttlebody on it and make yourself a happy camper once more--might should check on the compatability of the two engines and then make a choice on what to do
