Over heating problem!? please help!

I would say you have an air lock in the cooling system and it needs to be bled. Your water pump is cavitating, meaning an air bubble developes around the water pump impellars, an can't circulate the water.

Check your coolant level and see if it is down. If you have checked heads you will notice your engine oil beginning to turn milky white.

If you want a more complete check for cracked heads, plug all spark plugs, and if you can get a coolant pressure tester, pump it up to 12 or 13 psi and then crank the engine over. Watch for water to spray out of one of the cylinders.

When you say not leaking antifreeze has your coolant level gone down at all? and is it that you have seen no leaks where you park it? What worries me is you can smell it when warming up, have you felt the interior floors to see if damp and do you get any condensation if put blower onto screen, if so then heater matrix is leaking if not could be down to headgasket and/or cylinder head leak.

• see if you can hear the fuel pump click over when you turn it to start position! this may be a fuel pump?

SOURCE: Smoke comes from around engine

If you saw where the oil came out then that is the repair needed. It may not leak enough oil to get to the ground. Engine temp will make the oil leak smoke before it ever hits the ground. It may be valve cover gaskets because when they start to leak the oil gets all over the exhaust manifold and the exhaust manifold runs very hot. Rate if this helps
