Oil sludge in the cooling system

i'm trying to determin if i should pull and replace eng or pull the head.

    I have oil froth in the coolant, it doesn't seem to use much oil and there is no froth on the dipstick. the car has only 106K and runs fine. maybe I will do the compression check.

Could also be a blown head gasket. The first thing I would do is to run a compression check on each cylinder and look for a large pressure variation on one of the cylinders. If you check the oil dip stick after it has been running a little is there any sign of the oil being frothy. Another thing to check while it is running is to run the engine with the radiator cap off and check for bubbles in the coolant. The compression check will tell you where the problem is.

Good luck Loringh

I have sludge in the coolant in my l997 Olds Aurora/

pink sludge --very serious
it is a failed transmission oil cooler allowing transmission oil into the cooling system
Oil and water do not mix and in a cooling system prevents the heat transfer from the cylinder wall to the coolant and from the coolant to the radiator fins

My 2006 pacifica has yellow sludge in my coolant resivoir

Probably engine oil, unless you have been adding water pump lube. The oil can come from a blown head gasket, or if you are lucky it can be the transmission oil cooler inside the radiator has failed and is leaking. Either way, DO NOT RUN vehicle until you fix the issue and change all fluids. There is a tester that is used to pressurize the radiator which may help determine what has failed. Many parts stores have a loan-a-tool program that may have this tester.

It depends on what is causing the brown sludge. More information is needed to make an asessment and prescribe a solution. Brown sludge can be caused by engine oil or transmission fluid mixing with the engine coolant, or it can be caused by severe corrosion in the cooling system due to lack of proper cooling system maintenance.
The engine oil cause will most likely require head gasket replacement.
The transmission fluid cause will require radiator replacement.
The severe corrosion cause will most likely require a complete cooling system overhaul to properly correct it.

I have got a citroen saxo it is an R reg. There is no option to choose a saxo sorry. My broken head gasket caused the cooling water to mix with the oil. And now the sludge blocks it all up. Does anyone...

About the only way you are going to get that right is to fill the coolant system with a very hot detergent solution and let it stand for a while. Flush and back flush the system (Remove the thermostat for full water flow. Unfortunately you are going to just have to continue doing this until the system is clear. You could use a detergent based engine cleaner or just make up a solution using a powerful washing detergent, but do not use any solvent or oil based cleaners, they will chew up the rubber hoses and seals in the system.. (The radiator could be cleaned at a radiator repair facility).

Why is water resevoir keeps getting contaminated,oil cap is clean ,car isn't smoking,look's like gunk in it .

oil is getting into the cooling system through the oil cooler. the oil cooler is located under the intake manifold. After replacing oil cooler you need to flush the cooling system several times to remove all of the oil sludge

Heater not working,sludge in header tank on ford courier van

Sounds very much like your cooling system is full of ****. It would pay to have the cooling system flushed, including the radiator. If the sludge builds up it blocks the heater tap. This could also cause problems in regards to the cooling system as a whole, and potentially blow a head gasket. Check the color of the sludge. If it looks like a chocolate milkshake, it may denote a head gaset problem, and the sludge may actually be oil in the water.

Check the engine oil for a yellow sludge you should see it on the dip stick.If its just oil then it could be your oil cooler leaking oil into the water system.Or the only other thing that would cause this sludge in your water is the head gasket.

I have the same problem with a renault kangoo diesel , black thick oil in coolant --nice clean oil in motor , you have an oil cooler leaking oil into the cooling system , replace the oil cooler , I have not been able to get the black sludge out of the coolant internal parts , heater is blocked too , I thought of using kerosene to break down the sludge , but worry it might damage the hoses and they are not cheap, good luck

Premature oil pump failure 04 A4 3.0 Quattro

Absolutely - the 1.8T engine is known for sludging issues. If they diagnosed oil sludge then your engine is covered no matter the mileage. The oil sludge builds up in the 1.8T no matter how well cared for it is, and the sludge can block the oil pickup screen on the oil pump (it's an extremely fine mesh), causing oil starvation and taking out the engine in the process.

Go to and do a search there for "oil sludge" and the information will come up. You can learn all about it there. But if your engine has the sludging, and you have receipts proving the oil was changed at the proper intervals, you will get a new engine free of charge - one of the members there is an Audi technician and I remember him posting that he'd changed out a 180k mile engine under warranty due to sludge.

Oil in the radiator

are you sure its oil in the antifreeze? oil is brown. your van should have dexcool wich is orange, not green.(looks red sometimes)check the coolant again and check the oil. if it looks milky or foamy, there is coolant in it. sounds like it may be a blown head gasket. not good. stop driving it if you want to save your engine. you need to replace the head gasket/s, and flush the cooling system.
