Oil smell like gas

[samonline]

My 1976 450 SL stop starting and running. I pull the oil stick , It smells like gas. Oil is very thin. So what happen and what should I do from this point to fix this problem. Thanks

First thing you gotta do is replace your oil.
Then you need to figure out why it is over-fueling.

leaking injectors, common cause, I'd start there. What color are the plug tips?

Change oil fast!!! You are dumping gas into the crankcase.

Did anything get done to it before the problem arose?

Are you getting spark to the plugs?

Could the fuel distributor be over supplying?

Could the ignition spark system be malfunctioning? (Coil, wires, cap, rotor, Ignition Control Unit, spark at the right time, etc...)

It sounds like something is not letting you get spark. As you try to start, the fuel is not ignited, and it just runs down the cylinder into the crankcase.

I don't know you 'wrench skills' and familiarity with the system, but if you break the problem down into "What works?" and "What doesn't work?" sections of the ignition process, you should be able to figure it out, if you have some familiarity with how it's supposed to work.

Don't panic!

While still learning the D-Jet system on my car, I wasted 2 weeks and a small chunk of money by not checking the points adjustment. Something you don't have to worry about on your K-Jet.

Good luck,

I did change the oil, filter , new rotor and spark plugs . There is sparks from each spark plug . Car still does not start . My question is , What is the icu role .Do you think the icu could be bad that will not allow the car to start? And How can I check the icu to make sure it is working .Thanks

Could be faulty crank position sensor not giving signal pulses to ICU. Pull sensor plug from ICU. Looks like a co-axial connection. Measure resistance. If no resistance, you found the problem.

I change the icu , but car still not starting, I have a feeling that the car is not getting the sparks on time to ignate the fuel from the injectors, that's why fuel is not burning. How can I adjust the crank position sensor to get the sparks on time when injectors spit the fuel out.?? Thanks Sam
