i changed the oil in my 77 924 na and noticed a great amount of fuel mixed in with the oil. im wondering if someone can help me figure out why i have gas in my oil and why the car wont start. im thinking fuel injectors are bad, or my CSV is bad. or could it be somthing else? fuel distributor? please help

Most likely you are running rich, is your tail pipe coated with black soot?

Try unplugging the connector from the CSV. If you're running that rich, as Paul suggests, this might get the car started so that you can then see the effect of adjusting the mixture.

Fuel in the oil is normally the result of lots of cranking with fuel flow but without starting; all that gas washes down the cylinder walls and into the pan.

You are getting spark, right?

Fuel distributors can fail in a mode that keeps one injector constantly spraying. I would pull the injectors out and check the spray pattern and volume before doing anything else.
