What would cause there to be oil in the radiator but not water in the oil?

Pressurized oil lines go from the block through to the head. If the head gasket is leaking at that point and allowing a small amount of pressurized oil to seep between the line and the coolant jacket you could get oil in the radiator. Another possibility is that perhaps someone used water pump lubricant which is nothing more than an emulsified oil (oil blended with water). Over time the oil can separate from the coolant and that might be all you're seeing, especially if it isn't much oil. If it's RED oil it could be comming from the transmission cooler line. That runs through one of the radiator tanks and if the transmission line is leaking you could certainly get oil in the radiator... but it' would be red.

In a 93 Olds Silhouette what would cause there to be oil in the water but no water in the oil?
if this vehicle is automatic,the most likely cause would be the transmission fluid cooler. it is a tank inside the radiator that cools the transmission fluid. if by any reason the tank leaks it would contaminate your water/coolant/antifreeze. answer a cracked head will allow oil into water jacket in head, going from there thru to radiator if it was a bad head gasket, u would have water in oil instead
What can cause oil to get into radiator?
Cracked Head Cracked block Blown headgasket Failed oil cooler (water over type)
What would cause oil in the radiator coolant?
blown head gasket....not good. Could b Transmission fluid because the transmission cooler is in the radiator-especially IF the water has a red tint 2 it,IF it has a automatic transmission.
Can driving without oil and water in coolant cause engine to blow up?
no oil in engine or water in radiator will cause engine to seriously o/heat! and eventually seize! major engine damage!!
Your radiator has brownish orange oily gunk in it what is it?
It means that your engine oil is mixing in with your radiator fluid. You probably have water in your oil too. I would take it in and have it fixed.
What would cause engine oil to be in Radiator of 1976 Ford 390?
broken engine gasket.
Why would there be oil in the radiator and no water in it?
Bad Head Gasket. See a mechanic ASAP..
Why is there oil in the radiator but the engine oil level has not gone down nor has the transmission oil the radiator is also losing water but no water is in the oil or transmission?
How much oil is in the radiator? just a tiny amount or a good thick layer? It's possible that they are leaking in to each other, but the sealed nature of the radiator means that the levels stay about the same in both systems, they just exchange fluids. If there is water in th oil system it may not be present when you inspect the filler cap as water has greater density than oil and would therefore be at the bottom of your oil tank. It may be worth draining your oil tank and checking for water in the oil as it exits through the sump drain valve. Alternatively take your car in for a service including an oil & filter change (not expensive) and ask them to check for leaks while they're doing the change. Whatever the outcome, it's not good to have water in your oil system as this can cause problems, but it's not such a problem to have oil in the radiator. But always best to find the root cause just in case its something more serious.
Will gasoline in your oil cause your oil cap to be slightly foamy?
It can cause your oil cap to blow right off, foam around the oil cap is more likely to be water or coolant. Get it checked right away because it can damage your engine. It's usually a sign of a bad head gasket, it lets water into the oil and oil into the water. Check your radiator to see if there is oil in the water and if the water is low.
Wot would happen if you put engine oil in a car radiator?
the thick liquid would plug your radiator and ruin your water pump. and destroy your engine.
What can cause oil in the radiator?
It Could Be a Bad Gasket that causes water to mix with coolant more than likely you will see white dough like substance in radiator.
Water pump leak oil in radiator?
You did not say what you are working on, YEAR AND ENGINE SIZE. But in most cases or designs the water pump can not leak oil into the coolant. The water pump has nothing to do with the engine oil. Does the engine have a engine oil cooler on it ? That would be 2 oil lines just above the oil filter that runs down the side of the engine oil pan a go to the radiator. There are tubes inside of the radiator that oil flows through and they are none to leak oil into the engine coolant that's inside of the RADIATOR. If they are leaking then REPLACE RADIATOR. BUT like I said I don't know what you are working on. Would like to help you with your problem, But need more INFO. NEUTZ.
