Well,if they did the head,they should've checked the PCV valve also, and so I'd guess the increased pressure of the pristine head has taxed your piston rings,which might've had some blowby anyway. don-ohio (:^)

My 2011 Kia Cerato "S" has been using a lot of oil. The cylinder head was re-conditioned and engine serviced. The now engine blows smoke every time on starting. What is the probable cause ?


depends on how the head was reconditioned
were new valve guides installed along with new valves
were the stem seals correctly fitted
was a compression test done to determine the wear condition of the engine
smoke on start up is oil in the combustion chamber from valve stem seals , worn rings , sump pressure from excessive blow by through the line to the air inlet
check for oil leaks ( filter etc ) but using a lot of oil indicates ring problem, excessive bearing clearance overloading the oil control ring
try using a heavier grade of oil 30w 50 or oil for worn motors

Sometimes stalls after starting either warm or cold. Kia cerato 2011 95,000


Neither can I. Unless you let me have it for what ever time it takes to stall. That costs money. You can buy a cheap code reader. when it happens, Check the codes before you turn it off.

Im getting codes P0011 and P0014 on my 2011 kia serento. Is mean my camshaft sensor is bad? if so where is it?


These codes have to do with the CVVT(continuously variable valve timing)solenoid. I guess it is a 2.4 liter engine, the solenoid is located right above the power steering pump at the #1 cylinder in the cylinder head. If it is the 3.5 liter it is located on top of each cylinder and is accessed after the intake plenum is removed. Either way, the solenoid controls valve timing of the exhaust cam via the solenoid which uses oil pressure to advance or retard the timing. The first step is to verify proper weight of oil and level. If the engine is over due for service, get it done. If the oil is not an issue, then the solenoid is becoming sluggish in advancing or retarding the camshaft and should be replaced.

I'm looking to purchase a used car. I've been doing online research and saw this webpage http://www.usedcarsmells.com . They talk about exhaust color and smells. Is it true that you could tell a lot about...


Yes this is correct, you can get important information from the colour of smoke from the exhaust:

Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray smoke at startup because oil leaks past the seals into the cylinder after the engine shuts down.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

How do you know if you have a blown head gasket?


you my have thick smoke coming out of your tail pipe or oil leaking out on to your engine

I own a 2002 Kia Rio RXV and my husband decided to change my spark plugs. When he pulled them out of the engine, they were all covered in oil. What would cause this and is it worth fixing?


You have a 4 cylinder and there are seals in the cover around the spark plug holes. You can replace these with a rocker arm cover gasket set. Costs about $25.00. The oil does not hurt the sparkplug, but over time it will affect the plug wires/ boots and cause a misfire. these are not hard to replace. Your call.

Car smokes in front when started then goes away


Blown head gaskets cause this symptom.
Also, oil leakage on to the hot parts of your engine can cause this problem.

The smoke can be either antifreeze or oil that accumulated in a plenum or low spot that gets hot when you start your engine.

Its blowing oil out of the oil cap why would this be ?? also i bit of white smoke then came out the back


The oil level may be too high.
Is the filler cap tight?
blow-by in the cylinder piston rign area. A wet test of engine compression will detect this.
A bad had gasket. Engine will be over heating as water is being used up during combustion.
Bad head gasket. Could explain white smoke in exhaust.

If the engine is overheating I would be suspecting a problem in the head area.

Good Luck. SnugglePants
