340 engine oil consumption ???
I would pull the spark plugs on the same side as the wet exh pipe. Then pull the others, and see what they look like. If any are wet with oil, or black and gummed up, thne you have an engine problem. While they are out, pick up a compression gage, and check each cylinder one at a time. Turn it over a couple of times per cylinder, and keep the throttle propped wide open. (no plugs, so dont be afraid of it firing). Write each cylinder's reading down, and post the results, along with any plugs that were bad, by cylinder number. If it bent pushrods, you need to know why. You may have a damaged guide from the pushrod thing, or a leaking intake gasket, or bad rings, or ,or, or....But really, you need to narrrow it down.
