1970 Coronet
I recently got a 1970 Dodge Coronet 440 from my father that has been sitting for 15 years. I did a major tune up and it started right up. I now see that oil is only pumping from one side of the engine. I tried flushing it, but that didn't work. What should I do now?

do you mean you have the valve covers off and its only pumping to the top of one head?
further more we would need more information to possibly help you out such as
what size engine?
how many miles on the engine?
did you hook up a pressure gauge to see what psi you actually have?

Yes. I took the valve covers off and started the engine. Only one head was pumping oil out of the push rods. My coronet has a 318 engine with 67,000 miles. I have not hooked up a pressure gauge to check the psi.

the stock rocker shafts have a notch on one end of them... That notch always goes DOWN & To he left, no matter what side you are working on, Drivers side the notch should be down & toward the front of the car, on the pass side it should be down & toward the rear of the car. So make sure they are not on upside down or backwards etc.
If rockers shafts are on correctly then it gets more complicated, has the engine ever been apart and how was it maintained?????
Basically in an LA Chrysler the oil for the rockers comes up an oil feed passage in the block that gets fed off of the #2-4 cam bearings...... The drivers side gets fed off of the #2 cam bearing and since you have 67k its possible that the bearing has spun blocking off the oil feed( not probable with 67K but anything can happen) or if any large chunks of debris gets into the oil passage in the block it can clog it easily as well.....
i would hook up an oil pressure gauge and see what you have first and then go from there
