Answer 2

If you have milky coloured oil then you have a crack in the head, so take it back and demand a replacement under warrenty. If it's fairly new though it's likely the fault is elsewhere unless you drive like a maniac. Put some block seal in it, this fixes almost all leaks, even heads, gaskets, and primary engines. The only way this won't work is if it's a pipe which is simple and will empty the engine in minutes, or if it's a water pump which should be fairly obvious if you look at it while the engine is running. It will be located on the fan belt or cam belt.

Oil in the water (in spite of the undeniable fact that in many circumstances not water in the oil - if the oil tension is stable, water in basic terms gets into the oil for a quick time whilst the engine is stopped using fact the coolant remains pressurised however the oil isn't) a great variety of steam or smoke from the exhaust, loss of capacity, overheating, coolant loss If the vehicle is chilly and the radiator hoses get not easy (pressurised) formerly the engine is heat that's extraordinarily plenty info while you're undecided, maximum garages can "sniff" the coolant for lines of oil - the attempt is usuallly extremely sensetive EDIT Water or "mayonaise" in the oil isn't stable info via itself using fact it could produce different motives and as I defined above you're able to have a failure with out info of water in the oil As JIM pronounced the exhaust will scent different - burning anti-freeze is like not something - as long as you have applicable parts of antifreeze in the coolant EDIT*** thank you for the added - as i pronounced milky oil is in many circumstances not recent - sound very very such as gasket or head failure you may get a storage to purpose the coolant in case you cant see oil in it, just to ascertain - sorry

Answer 4

check the dipstick if the end looks creamy head, gasket has blown. also have a look at the oil filler cap, if that is creamy possible gasket problem. unscrew the water fill cap dip your finger in the water, when its cold obviously, if it feels oily , possible gasket problem. sometimes you can even see the oil floating on top of the water. check around the engine for oil leaks.
hope thats helped you

Answer 5

take off the radiator cap and have a look at it, if it has a white residue on it your gasket has definatly gone.also look for signs of water in your oil,and vice versa.white smoke from your exhaust is also a sign.Do you have a water leak,with your car running look under the bonnet for signs of leakage,water scwurting out of pipes,how often are you topping up.does your car need oil in ? that can also make your car use more water.

Answer 6

The usual signs are white smoke particularly in the morning , internal pressure when the rad or header tank cap is removed . (do not remove cap when hot it could scald you) overheating the sounds of engine boiling after a short run . engine oil turns a milky brown colour(but not always ) Water disappearing with no outside signs of a leak . when engine is cold start car with rad or header tank cap off,make sure its full with water leaving the waterline about six inches under full, look for heavy bubbles rising all the time

Answer 7

Loss of water or oil in the expansion tank , water in the engine oil , can be cheked by looking at the condition of the dips tic for residue , look for white gunge on inside of cap on rocker cover { the cap you undo to top up engine oil ] finally white smoke from exhaust .

Answer 8

Water coming out of the exhaust pipe, bubbles coming out of the radiator while its running with the cap off, water in the oil (the oil turns grey) A simple radiator pressure check will let you know it it's blown.......

Answer 9

i own a repair shop,and if they or who ever didn't have the head checked ,and trued up on it it probably still has a slight warp in it but the signs of one blown are having to add a lot of coolant to it ,and a slight miss from time to time,and also a loss of power and maybe a lot of vapor coming from the tail pipe at al times, those are the most common signs,,good luck,i hope this help,s.

Answer 10

Overheating,
Coolant in the oil, usually appearing as white foam.
Loss of compression on 2 adjoining cylinders
Loss of coolant, but no leak.
On older cars, lots of white smoke, steam from the exhaust. Modern catalytic converters mask this symptom.
