My oil is looking milky but, I don't drive the car that much

Milky oil is usually caused from condensation from some where either antifreeze getting in, or if you are doing a lot of short drives where the engine doesn't get a chance to come up to full temperature. If there is water in your oil it will cause your knocking sound. I would change the oil and put in some fresh and see what happens.

first, is it white smoke? if so, you probably have a blown head gasket. take your oil cap off and look at it. does it look normal or does it look milky. if it is milky inside, then I am sorry, looks like a major repair and I wouldn't drive it. also look in your radiator and see if there is oil in it. if so... same problem. if it is black smoke, then you are burning oil or transmission fluid. either way, you need to take it to the shop..

Sounds like you may have a blown head gasket or a cracked head. There are test that can be done to check this the easiest and cheapest method I use is drope a few dropes of oil from your engine on something hot like the exhaust if it boils there is good indication there is coolant in your oil as the flash point of coolant is a lower temperature than oil

check the oil and see if it looks milky from a bad head gasket or cracked head

look for coolant in your oil ,the oil will look ''milky'' if there is coolant mixed in it. if you have milky oil then you have a blown head gasket. if thats not the case then we have to look elsewhere. hope this helps

check the oil and if it looks milky he probly needs a new head gasket. If the oil looks normal you probably nee to check the thermostate and get a mechanic to give your radiator a pressure test to check for leaks

Check the oil before you start it, it should be dark but clean. Inspect oil for metal debris/shavings, that indicates improper engine wear. Also if the oil seems gunky or milky looking, walk away, there is a possibility that there may be engine damage such as a broken head or head gasket. Check the radiator or radiator tank reservoir for milky residue which will also point to a broken head or head gasket, it should be clean orange or green looking water depending on the type of antifreeze used. Last, turn it on and remove the oil fill cap and feel for excessive blow by. If you feel air coming out of the engine when you put your hand over the fill tube/hole, then leave it. There should be very minor blow by, but if it looks like it's ready to inflate a balloon, walk away.

Yes, when the temperature rises the likeliehood of a blown head gasket also rises.

If the oil looks milky or foamy with light brown color, you know that the head gasket has blown.

If you are loosing coolant with no leaks, it is either getting into your oil or going out the tailpipe. This would indicate either a blown head gasket or a cracked head, possibly both. You can check for water in your oil...the oil will take on a milky look. If it is coming out the tailpipe you may have a drip where it terminates. Also you can hold your hand a few inches from the end of the tailpipe and moisture will form on your hand. Good Luck. Wish I had better news.

milky oil means blew a head gasket check for oil in the antifreze
