Protege 1.8L (FP-DE) blue smoke when cold start

Hello Everyone! I have a 2004 Ford Laser Tierra which is the Mazda Protege under Ford Badge. The model of the engine is a 1.8 litre FP-DE engine, the problem is when cold start it makes a lot of blue smoke but when the engine reaches the operating temperature the smoke is all gone. What do you guys think is the problem?

Here's some information about it.
Your 1.8 liter engine is probably the same as our 2.0 liter engine.

It's not good news.

Thank you for the info! I'll look at the valve stem seal first if the smoke still comes out I'll check the ring.

Do this test to find out if it's your valve seals or your piston rings.

Chances are REALLY good that it is not your valve seals.
