so the car smokes - so what? the motor sounds GREAT - I'd drive it til it goes boom, then worry about it
That sounds like a very aggressive cam, which has a lot of lift you are running excessively rich, you need more initial timing this will clean that idle up nicely and your idle is low go up a couple hundred RPM's
Mark the plugs on the top of the ceramic with a marker. Pull and check them. If the majority of the oil and crud is on the lower part of the plug it is the rings. Upper part of the plug and it is from the heads.
I had a similar problem. It turned out to be a vacuum modulator. Tranny fluid was getting burnt up like no tomorrow
I think my carb is the problem, the car is running insanely rich and the left mixture screw does not change anything at all on the carb. Guess I'm going to have to take it off and rebuild it.
Have recently changed to a different type and weight of oil? Just trying to eliminate all the possibilities.
Yeah I've been getting ethanol lately and when I bough the motor there was no telling how long it was under the tarp. And I have not changed weights in oil it's always been 10w-40
