Blown head gasket. That milky look is coolant mixed with the oil. STOP driving this vehicle until you have this repaired or you will ruin this engine.
this is usually engine coolant leaking in
Any time your engine oil is milky it means you have water in it It's got water in it from somewhere. Probably a blown headgasket. Hopefully not a cracked or warpped head.
A cracked radiator will NOT put water in the engine and make the oil milky. A bad head gasket WILL put water in the engine and make the oil look milky. That does not neccessarily mean you have a bad engine. Have someone fix or replace the radiator and replace the head gasket. It could be a good engine for a long time yet
drain oil,raditor.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
probably a blown head gasket if the oil looks milky or has bubbles in it
You have water in your oil. Possibly from condensation. Run the engine only long enough to warm the oil and change it.
Milky oil in a 5.7 Vortec engine is typically caused by coolant contamination, often due to a blown head gasket, intake manifold gasket failure, or a cracked engine block. This allows coolant to mix with the engine oil, leading to a milky appearance. Another potential cause could be condensation buildup in the engine, especially in colder climates, though this is less common. Regular maintenance and monitoring can help prevent these issues.
White smoke at startup, loss of anti freeze and milky oil indicates to me a bad head gasket.
Milky oil is an indication a water in the oil. Could be from a failed headgasket, a leaking oil cooler, ir a malfunctioning pcv system. Continuing to drive that vehicle in that condition will do serious damage to the internal parts and shorten the life of the engine greatly.
The head gasket is gone and water or coolant has mixed with the engine oil. Replacing the head gasket is no big deal.
Milky means one thing, water in the oil! Generally this means coolant from the engine is getting into the trans usually through the oil cooler in the radiator. This is very very bad and will quickly ruin the transmission.
