That is a classic symptom of a leaky head gasket. You will need to change this asap to prevent further damage to your engine. You would be as well do ing a piston and base gasket change while your at it. And remember to get a new set of cylinder head bolts, for when you put it all back together again.

Cheers,

Andy....

Hi there I pour water in to my radiator on my ktm 125 sx 2007 and the water comes out the middle of my gear box casings and of course it's mixed with the oil. Any ideas was thinking inner water pump...


Your cooling system leaks into the engine. You need to check the water pump for damaged oil/water separator and cylinder's head gasket next.

My yamaha tdr 125 keeps over heating. put new thermostat in plus temperature sensor, water pump is all workin, pipes are all clear, had new gaskets, piston, piston rings the lot done to it but it keeps...


Hi, Ally and the usual suspects are:
1. Engine oil level and SAE weight are too low or not circulating.
2. Insufficient or blocked air flow over the engine.
3. Heavy combustion chamber carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, or CMP sensor.
5. Carburetor jetted too lean.
6. Leaking intake or exhaust valve.
7. Water coolant old or low change every two years.
8. Water pump failure.
9. Radiator clogged, cap loose or malfunctioning.
10. Radiator fans not coming on.
11. Clutch slipping, brakes dragging, heavy load, towing a trailer etc.
12. Idling too long without moving.
13. For constant hot weather temperatures, mountain, or desert riding conditions consider adding an oil cooler and or cylinder head cooler.

Heating has stoped working and there is a little water in the oil, think radiator may be leaking, does my car just need a new rad


water in the oil will turn the oil brown like mud,is that what you see? if so,then you have a blown head gasket,do not run motor if this is the case as the motor wiil spin a crank bearing or lock up.are you sure about the water in the oil? look for real brown oil just like mud with bubbles on the oil dipstick. if the heats stopped working it may be because the radiator's low on fluid. look in the radiator for low coolant,if you can't see the coolant when you remove the radiator cap,it's low. with engine cool,remove the radiator cap 1st then start the engine. do you see steam and fluid blowing up frome the radiator? if so,you have a blown head gasket in the motor. head gaskets can blow and leak water into the oil or oil into the radiator. or blow and leak into the exhaust sysytem and blow coolant out of the tail pipe. three different ways for a head gasket to blow. usually the head gasket only blows when the engine has been run really hot!!! hope this helps.thank you for choosing fixya .com

I have oil leaking into my 1990 ford festivas radiator,what could be causing this?Is this a serious problem?


It could be the transmission oil leaking since the transmission fluid goes through the bottom of the radiator to cool off. You may need to replace the radiator. But if it's motor oil then there is a blown gasket on the motor or crack. Look at the motor oil on the dip stick and see if it looks normal or is milky looking indicating that there is also water in your motor. If it's just the radiator then it's not a serious as it is if the water is in the motor. Motor will be damaged with water in it.

Suzuki RM 125 water is mixing with the gearbox oil how do I fix it, or what is the cause. The water is leaking from the cooling system and turning the oil milky. I have just changed the oil and filled up...


Did you do the reassembly yourself? If not, take it back to whoever did because the reassembly was done incorrectly. Oil and water mixing can only happen at the top or bottom ends of the barrel. Either the head gasket is not seated properly or the barrel to casing seals are not properly installed

The water pump is in the motor case and has a leaking seal. Anti freeze is leaking past the water pump seal into the transmission. Take your water pump apart and replace the seals. The fluid should be escaping out a weep hole in the bottom of the pump, so when you have it apart be sure and dig the mud out of the weep hole to keep from filling the motor with anti freeze if this ever happens again. If there is no weep hole then it must not have been designed with one.

No problem here, just a question. i have a 2002 TM MX 125 strapped to a shifter kart, and just wondered where my EGT and water temp should remain during operation. When the motor is warmed up, EGT shows me...


A dry & tan colour is what you want to see of your plug colour. If it is comming out black yet dry your fuel/oil ratio is too rich. If you lean this ratio off regulary check the plug (initially) to be sure you don't seize it. The other symptom to look for if your fuel/oil ratio is too rich is wet/oily muffler tip.
Hope this helps Regards

Oil is a grey colour in the engine of my yz 125 2001


Your bike is water cooled. Some of that water is leaking into the gear box. The cylinder gasket is the likely leak. I would let the shop take a look at it instead of trying to fix it yourself.

But be sure there is not an external source for the water. Do you wash the bike often? Ride the creek bed often? Leave the bike where the lawn sprinkler gets the bike wet? Leave it out in the rain? Change the oil and keep the bike dry. If the problem comes back then go see the dealer.
