Oil spitting from exhaust

[bollcreate]

1970 Super Bee / 440
I have a good amount of oil spitting from exhaust, can you provide me places to look on the engine to find the source.

- Oil dripping into exhaust leak (via bad gasket)
- other leak
- fuel line issue
- carb issue

Driving me a bit nuts.

-Thanks

I could be wrong but I'm sure others will chime in, but this is how I see it...

The spray you see is water vapor in your exhaust system mixing with the black soot that coats the inside of your exhaust pipes. Fluid oil would have a hard time passing the muffler and spray out the tailpipe. Have you ever witnessed water dripping out of someone's tailpipe? Puting large cubic inches behind that makes the water spray out. Its normal.

How long has the car been sitting without being started.
Weather change, high humidity, choke on cold weather start.

Read the plugs, oil normally would come out of the exhaust as smoke, I agree that is probably condensation in a dirty pipe, read the plugs, if its running rich, lean it out a bit, that will get the exhaust warmer and lesson that effect after it warms up..

Does the car smoke?
Does this car stay stored for long periods of time?
Has the oil level changed?
I would be less concerned with oil and more concerned with cleaning up the combustion.. good luck...

If it is oil coming out the exhaust
it's coming from the bottom side of the intake leaking
or possibly the valve seals on the top end are bad
or blow-by from worn out rings on the bottom end

usually it would smoke pretty bad if it was oil, white smoke mainly

or a combination of all &/or something else
that's allowing oil to get into the combustion chamber,
like a blown head gasket,
faulty pcv, possibly pumping oil into the intake manifold
etc. etc. etc.

like said above it could be soot/carbon deposits/condensation build up in the exhaust,
for many different reasons,
maybe too rich/fat fuel system,
or bad/weak ignition system, not burning the fuel properly
{it could even be a timing issue combined with one or more of the others too}
or too big of exhaust pipes,
it's not able to develop enough necessary heat to burn off the
liquid/moisture/condensation, especially in cold weather conditions & short run times

what does the plugs look like ?


good luck & Happy Moparing

Rich fuel mixture, maybe choke not coming off soon enough.

A cold engine produces a lot of moisture in the exhaust system until things warm up. Hot exhaust gasses through a cold system=water and since the by products of combustion produces soot, it'll look just like that....even with an engine that's lean. That's what a choke does. It richens the mixture to allow the engine to run when cold until warm up and then the choke pulls off but you might check it anyways to make sure it's working right. Where I live, most of my cars didn't have a choke and would still do that your pic is showing and the cooler the weather, the more it'll do that.
