Exclamation If an 87 300D had a cracked Head, wouldn't it still Start?

I am trying to help someone diagnose an engine on a 1987 300D that will not start. I havent seen the car physically. My first thought when he asked me was that it suffered a Cracked head.
A month before it failed a deer hit it and the water pump pulley was dented,
Just before the engine failed, it lost all coolant and the Temp Guage hit "0". The driver found a puddle of about 1 qt oil near the front passenger side of the engine.
My feeling is that perhaps the timing chain cover broke when the chain snapped. My theory is that if the head cracked, you might still be able to start the car, but if the chain or timing cover snapped you might lose chain functionality and the engine would not start at all.
Engine turns over but doesnt start.
Driver of this car uses the car at hi speeds and the chain wasnt serviced for at least 250K miles after he bought it at 50K miles, the chain may have had 340 K on it!
Could any chain last that long?

It should run just fine with a cracked head, except for coolant useage. You need to look at the car but the oil on the ground doesn't sound good. If the oil was changed a timing chain is capable of going 340k, but their will be some stretch in it.

If the head was cracked badly enough it could have hydrolocked and done major damage to the internals. Don't know if that would absolutely prevent starting, but could be a factor.

Did he by chance have some type of insurance that covered the deer hit? Perhaps he may be able to convince the insurance company the engine damage was the result as well. Just tell him to make every third statement "everyone knows these engines are good for 500k" when talking to insurance people. If the agent shows any doubt just suggest checking on ebay

Questions?

Hello Carrameow
1987 300D that will not start.
Was the deer hit repaired?
Was the damaged water pump pulley overlooked?

Describe failure better please:
#1. Was it at 95 MPH or 45 MPH?
#2. Did he run coolant dry before he stopped?
