It's a beautiful morning! You turn on your car, suddenly you notice that your car exhaust smoking. Is it bad? Do you need to take some preventive actions? Well, before you do that, read some of this fact:

For the case of a cracked head that was repaired and then resurfaced. The repair probably lasted one year and then you experienced the same overheating problem. If the rest of the engine is in good shape, you may want to consider replacing the cylinder head. The reason you are experiencing the white smoke when starting it now, is probably the result of coolant in the exhaust system. Removing the head and inspecting it, will verify the suspected cause.

 

Head gasket or a cracked head problem? Remove all of the spark plugs.  Pressurize the radiator with approximately 15 pounds of pressure and wait for approximately ½ hour to 1 hour then crank the engine over and watch to see if coolant comes out of the spark plug holes.  This will tell you if your problem is a head gasket or possibly a cracked head.

 

My oil light comes on on/off while driving more on than off.  This has been going on for about 2 weeks. I'm also getting white smoke out of my exhaust pipes.  I was told it could be a blown head gasket.  Do you think so?  And, is it safe for me to be driving my car?  I am going to be getting it fixed.  But, I wondered what you thought?
Answer: The oil warning light indicates no oil pressure to the engine.  Check your oil level, if ok continuing to drive a car in this condition can result in serious engine damage.  The white smoke out the exhaust pipe could be normal. All car omit steam from the exhaust pipe when the car is cold. then as is warms the steam dissipates and can't be seen.
