Mein Auto: 2000 740i Sport
00 740i - Need engine!!! Help!!!!

Ok, so I'm new to this forum and BMW community. I think I got taken when I bought my car. It's a 2000 740i Sport. The owner told me when he shut the car off, it never started again. Paid the $1000 and had it towed home.
It has Nav and the interior is perfect, car has 104K miles.

I put a wrench on the crank bolt and cannot get the engine to turn. No water in oil, no external oil leaks ( as far as I can tell without the motor running).

Anyone in the Orlando, Fl. area know where I can find a good used motor?
Could it be something else?

Thanks in advance for any help / suggestions.

Mike

Remove the lower oil pan. If plastic pieces are found, the timing guides were worn, timing chain jumped and cylinders have "meet" the valves.

If the pistons and valves made contact.........can I just replace the heads, or do I need a new engin assembly?

Thanks for the reply.

Well, if cylinders are OK, and you replace the heads, it will be wise to resurface them+all timing guides and tensioners and gaskets replaced. Add the special timing tools and you will end up with more time and money spent than the used engine. But you should have a great engine to run for long time....

dont feel bad I bought a 2000 740il for $2300 last year and replaced the engine for $2500 now the ride is perfect love it not to mention i enjoyed the challenge of working on my Bimmer myself here's a website just incase you decide on replacing the engine, www.car-part.com. click on the one that says 140 million parts.you'll be able to see most salvage yards that match your parts closest to you part grade and sometime milage and price, good luck.

Thanks for all the suggestions!

I bought a complete running engine today........unfortunately its a non vanos motor.

Can I put my vanos heads on the non vanos motor?
I will be removing the vanos heads from the bad motor next week and taking them
to a machne shop for inspection. I did find a set of vanos heads completely re worked for
$1100. Should I just buy those instead? Any help will be appreciated.

Remove the heads and lower oil pan, see what you find and go from there. You will need new valves too if the timing chain jumped.

With the M62 enine, you might match it ... you need a different DME, re-programmed, and I don't know if will match the transmission (software speaking too).

The cylinder heads, might not match. I'm not sure.

re

Part it out and buy a running one you can easily get $6,000.00 to $10,000.00 for the parts and buy a good running car for $8500.00
