Engine smokes in the morning and after parking for long. Normally engine shows smoke in the morning when you just start it which is actually steam not smoke and would only do that for 1 to 2minutes unless it is raining or the weather is very very cold.

But if you are certain Engine is smoking, what is the color noticed is it black, blue or what?

Also shortens oil

if your Engine shortens oil, it could be an internal or external leak, so check around the Engine area if you notice oil stains, also start the car and leave gear in park or neutral and depress the accelerator to 2500rpm then check the exhaust if smoke is oozing out then you have an internal leak (it's a 2man job)

Change engine! EOD

My instincts tells me, the colour from your exhaust tailpipe is BLUEISH.

1. As long as this happens when the engine is cold, and after parking for a while, that depicts your valve stem seals are weak, and have lot their abilities to seal the intake/exhaust valves port.

2. The oil shortages you're experiencing means the oil rings are also weak, and can't provide the necessary oil wiping of the cylinder bores(walls).

Should you replaced the engine?
Its up to you here. If you've got the cash, and you're comfortable, and certain about the engine you're getting, then go ahead.

Alternatively, usually replacing the valve seals and oil rings takes care of the problems.

Choose what works for you.
