wont start
i installed a new transmission wiring harness, now x5 wont start. everything comes on. battery is fully charged, but wont turn over. computer wont reset by using two buttons on the dash. was starting before.

When BMW launched the X5 in the 200 model year, the company was careful to not call it a "Sports Utility Vehicle," opting instead for the somewhat cumbersome "Sports Activity Vehicle." Indeed, the car was likened to a5-series wagon "on stilts," and initial criticism aimed at BMW said the company was trying to keep up with other car makers by launching its own version of a luxury SUV.
Despite weighing in at nearly 5,000 pounds, the V8 engine delivered plenty of power. The X5 was available in a single trim during its debut year, the 4.4i, with a 4.4 liter engine capable of producing 282 horsepower.

the valve cover gaskets got replace. But now I notice the oil is in the bottom of the spark plug..could that mean something serious?
I have a BMW 18 years old. The car passed 128,000 km. At the service, I was told that a chain was broken and that parts of the chain had destroyed the engine. That the whole engine has to be changed. How much cost a new engine for a particular model? Does the computer show any sign in advance that this will happen? Is it accompanied by noise and what kind? This is a picture of the chains in my car, and this is what caused confusion. I do not see this type of damage. Any additional informations, advice, about the problem or personal experience, is very welcome. Thanks in advance for help.
