SOURCE: oil appearing in radiator, 4afe engine, is there awater gallery behind oil pump? checked head gasket looked fine

Since there is way more pressure from the oil pump than there is pressure in the cooling system oil can leak into the cooling system and coolant not leak back due to the pressure differential.It is very easy to have a head gasket leaking and not see where the leak was with a visual inspection after disassembly. I would inspect the head for cracks and if it is ok clean the block and head and have the head checked for warpage and if it is ok replace the head gasket and you should be good to go.

hi there.
Water in the engine - Water can get into your oil sump in two ways: ... Water in the oil- Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is getting into the oil.
Water in engine oil
If you found water in oil car , this water engine car section is for you!
Water in car engine? Water should never be allowed to get into the oil in your engine or gearbox. Otherwise, it will result in significant foaming, dramatically reducing the product's lubrication properties.
Water in the engine - Water can get into your oil sump in two ways:
  • Water in car - Water condensation in cold air or combustion gases: this phenomenon is extremely rare and only occurs at specific temperatures.
  • Water in the oil - Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is getting into the oil.
Water in motor oil can cause serious damage to your engine - the oil will be denatured and no longer effectively cooled.

My car has water in the oil

If you have water in your oil then sadly you have probably cracked the head or similar allowing the coolant to pass into the cylinder then down into the sump. If she is all you have you could dismantle and have a look in there to see what damage is done, but might not be worth it.
You should be able to see if you have lost a frost plug, it's probable that initially, the steam came from a radiator hose, and once she lost her coolant It overheated causing the head to crack. It won't be just the head gasket. Good luck

1991 toyota pickup, overheating problem, there is water that I know getting into the oil. I just bought a new head and gasket plus the timing cover gasket as well. ran it today and still blowing water in...

Coolant or water in the oil can be from a head gasket leak, but it can also be an intake manifold gasket or a crack in the block or head etc. I would begin by removing the spark-plugs and then pressurizing the cooling system and checking each cylinder for signs of coolant entering them. If the cylinders stay dry and coolant goes into the oil during the test you most likely have an intake gasket that's leaking. Don't run thee engine with coolant in the oil or you'll have catastrophic damage!

The car started running hot then loss pwer when i turned it off it wouldn't turn over like it was fighting for power.what happen?

Hi. The most likely cause is a blown head gasket. When the gasket blew water entered the pistion cylinder which fowled the plug and having water in the cylinder make it hard to turn over the engine. Pull the oil dip stick and look for a white milky residue on the stick, this would indicate water mixing with the engine oil, also look inside the radiator cap if the coolant looks foamy and oily the motor oil is leaking into the cooling system through the blown head gasket. If either of these conditions are present then the heads will have to be removed and a new gasket kit installed. The heads will also have to be sent to the machine shop for servicing.

Radiator 22r toyota

This sounds like a broken head gasket. Water is separated from the oil, but the oil is seeping through a crack or break in the gasket and getting into the water. This can plug up the radiator and prevent cooling system from working.

Head gasket is a good days work to even a weekend and requires a great deal of expertise and most of these have special tools for the head bolts.

I would get repaired as soon as possible, as water is getting into the oil as well and can vapor lock the engine.

How do i fix water mixed with my oil

This sounds like a blown cylinder had gasket. Although on some engines you will find core plugs below the rocker coverin the head.
