I have a polo classic 1.6 2002 model. Its smoking after idling for a while. On a start up it doesn't.


It depends on the type of smoke flowing from the exhaust. It will be either burnt oil smoke or burnt coolant smoke which is lighter in colour.

Check to see if you are losing radiator coolant with no sign of any external fluid leak. If so and you have light coloured smoke from the exhaust you probably have a coolant leak into a combustion chamber(s) by way of a blown head gasket or a crack in the cylinder head. This can be checked by a leak down test on each cylinder (A prior check of compression will show if you have any compression leakage on any cylinder but not the leak source).

Small amount of milk in oil


To check whether the coolant is entering into the engine oil or not, do the following.
- Park the car on a level floor.
- Check engine oil level on the dip stick and mark it with nail polish. Let it dry. Confirm the oil level. Put the dip stick back.
- Apply about 10 psi external pressure to the coolant system, while keeping caps in place.
NOTE: It is advised to use the coolant system tester. In case the tester is not available, ask any technician to do it for you. Or you can use a bicycle pump with gauge installed on it to pressure the system up to 10 psi. The system should held the pressure up to 30 Seconds.
- If the pressure is maintained for 30 Seconds every thing is good at this time. Ensure that the air is not leaking through your external pump system with which you are testing the system.
If the pressure drops, there will be a leakage some where. Either external or internal. External leakage can easily be observed while carefully examining the hose pipes, clips and joints on the engine.
Internal leakage can be determined by checking the engine oil level again.
- Take out the dip stick and inspect the oil level. If the engine oil level increases it confirm the internal leakage.
- Internal coolant leakage could be due to:-
1. Cylinder head bolts loose or under torqued. (Re-Torque the bolts).
2. Burnt cylinder head gasket. (Always use original spares).
3. Cylinder and head surfaces warped. (Surface grind the cylinder head on surface grinding machine and replace the gasket).
4. Any corroded lid in the cylinder block or cylinder head assembly.
5. Oil cooler, if any.
If the test report of above mentioned procedure is found to be OK, start the engine, pull up dip stick a little, open breather tube from the tappet cover, keep it open and keep the engine start for as long as the water vapors coming out of these points disappear and the engine oil will become clear to its original color.
At times it happens that immediately after replacing the cylinder head gasket some coolant may flow into the engine unavoidably and keep contaminating the engine oil for quite some time.
Hope that works.
Thank you for visiting Fixya.

Is there any way besides the head gasket for coolant to burn out of the exhaust?


That is the most common route into the exhaust, via the cylinder head but, is the vehicle a diesel with a water cooled turbo? If so, check the small coolant pipes, at the turbo, for flow and return and try to see (when cold) if there is leakage past the turbo seal.
If the vehicle is conventionally asperated, a pressure test on each cylinder, should reveal if the integrity of the head gasket is compromised.

I have bought a 99 land rover discovery and it is overheating


From practical experiences of heavy trucks, this problem is created by poor coolant flow thro' the Radiator Core. Flush cleaning the Rad. or decontaminating the exterior air flowways will not cure the problem. My recommendation is a Recore or after market replacement.

My 1999 Honda Civic is overheating frequently. There is no oil in the coolant, no coolant in the oil, no smoke or water from the tailpipe, no cooling system leakage and coolant is flowing through the...


Yes, check your electric fan for the radiatior. Either the sensor to turn it on is not working, a wire is broken, or the fan is defective. I had some problem on my Toyota but the fan blade was broken so the motor spun but did not good :(
