Oil in Coolant

On a 1995 E300D can oil in the coolant be caused by anything other than a problem at the head / crankcase interface. Is there an oil/water heat exchanger ? How would I test this?

Thank you!

Most likely a head gasket leak between coolant channels and oil channels. Need a radiator pressure guage and pump to test holding pressure in coolant system. No oil/water heat exchangers on your car. Usually just a head gasket replacement.

Serpintine bely slung off cold weather cause freeze plug to blow out

Change the oil right away, just in case coolant did somehow get into the crankcase.
Those rubber plugs should not leak. Did you clean the block good where the freeze plugs goes? It needs to be free of rust, scale, and dirt so the plug seals good. When you get it sealed tight you can monitor the coolant level to see if it leaks somewhere, like the head gasket. That is the only place coolant could get into the oil. Or if you have the coolant system pressure checked, you will find out if there are any leaks like a head gasket. If the system holds pressure, you are good to go. That means the gasket is good, and since no overheating, there is no or little chance you would have a cracked block or head-another way that coolant could get into the oil.

this oil is usually from the trans cooler in the rad that helps keep the trans fluid at operating temperature by the engine coolant absorbing the heat from the trans fluid .the cooler is a steel tubing in the rad tanks that the engine coolant runs around and absorbs the heat.when the cooler rusts through the trans oil seeps into the coolant.if it was motor oil it could be caused by a head gasket were the oil passage is next to the coolant passage in the gasket and it seeps into the coolant passage.however the coolant pressure is alot higher than the oil pressure and the coolant usually enters the crankcase.

I have oil leaking into cooling system, but no water in the engine. My oil level is dropping. What can cause this and what is the fix?

This is caused by a leaking head gasket. When a head gasket leaks you can get oil in the coolant or coolant in the oil of the engine or both. You will need to pull the cylinder head off, have it checked for cracks and if none are found have it machined flat again and replace the head gasket. Use only a quality head gasket set either from the Toyota dealer or a well known quality brand like Fel-Pro (available from NAPA and others). This is a job that requires some special tools and a great deal of car repair knowledge, time to do the job is about 6 hours.

What does a problem in the head gasket sound like? And how can you check.if theres a problem?

A couple of things will generally happen if you have a bad head gasket. Usually you will notice alot of steam and white smoke coming from your exhaust cause from coolant getting into the cylinders. Another to check for is coolant in your oil. Check your engine oil and if it has a milky look to it that meant that coolant is getting into the crankcase. Also check your coolant to ensure proper level and make sure that there is no oil in the coolant. Also if your head gasket is leaking exhaust into the cooling system it can cause your car to overheat. I'm not aware of any real sound that a bad head gasket will cause. It will probably cause the car to run rough and will eventually cause major engine damage if not repaired.

When i checked oil it looked milky

water or coolant is getting in oil. could be a bad head gasket. If the coolant level continues to drop, but there are no signs of coolant leaks on the ground or from the exhaust pipe, there is a good chance that coolant is entering crankcase and mixing in with the oil. check head gasket and manifold gasket for leaks.

Oil leaking into cooling system but no coolant in crankcase, also oil leaking from engine as it is all over frame and oil pan. engine starts and runs but heater does not get warm...??? 2003 saturn vue with...

Looks like a head gasket failure. Oil is escaping out of the engine and within the engine into the coolant passageways. The oil pressure system is run at higher pressure than the coolant pressure and fortunately this has so far kept the water from entering the oil and crankcase. I have no faith at all in any after-market product that claims it can repair leaks by simply adding it to the coolant or oil and taking a head off is not a trivial task. It may also be that the head has warped (this would also cause the leak) and this in turn will require it to be re-machined. Head gaskets are not expensive but due to the work involved this could be one occasion when a visit to a machine shop is the best option.

Coolant in crankcase

You may have a blown head gasket. One of the head gasket's job is to prevent coolant and oil from entering specific parts of the engine. Over time the gasket wears down and holes appear. Your cooland may have passed through these holes causing it to mix with oil. You would notice steam appear at the tail pipe, where some of the coolant may mix with the exhaust as a result of this.

Engine oil mixed in coolant

this would more than likely be cause by a bad cylinder head gasket. I would bet 89% this is your problem.
