SOURCE: overheating

It could be your head gasket.

SOURCE: Oil in over coolant tank

since you are running green coolant in a car designed for dexcool that may have contributed to a leaky intake gasket and/or head gasket. dexcool was specially formulated to run in the GM vehicles because the gaskets and seals can be easily distorted when the wrong chemicals are soaking them. oil in the coolant is usually either a head gasket or the lower intake manifold leaking into the cooling system. also if the intake gaskets werent done properly that would cause oil in the coolant as well. i suggest you take your car to a reputable shop and have it tested for a headgasket leak and to have the lower intake inspected.

next step is to remove the intake, you are on the right track, worse i ever found was a cracke block, but that was in a 61 t-bird which was repaired with jb weld ten yrs ago and still holding, but the intake gasket sounds right

Oil in coolant


possible internal intake gasket leak. make sure its not trans fluid from the cooler in radiator

What is a intake manifold gasket


Lets review what you said - - you were probably adding coolant since freon goes into the air cond unit.
If there is oil in the coolant tank, something is leaking to allow engine oil into the cooling system such as the intake or head gasket. If it is trans fluid it could be the trans cooler inside the radiator.

I have motor oil in my radiator and water reserve but no water in my oil, what could be the problem. Can an intake valve that is stuck cause this problem


your problem sounds like the transmission oil cooler lines,which are located in the radiator tank itself inside the radiator,has a leak which means the radiator needs replacing and the cooling system needs a good coolant flush to get all the oil out of the cooling system,be aware that you may have to replace all the rubber hoses as the oil will cause the rubber to swell and come apart,there is no connection between the cooling system and the valve system in any motor as they are completely separate systems

The reason for this is because your trans cooler(which is built into the radiator itself) has failed and burst causing trans fluid to contaminate the cooling system.The fix for this is to remove and replace the radiator with a new one and then flush your cooling system to remove all trans fluid.I hope I could help!!! Any other questions please get back to me and rate me accordingly.

If this is a 3800, Upper Intake Plenum or Lower intake gaskets are an inevitability. Head gaskets on these engines rarely go out! Seriously, don't get duped. I am doing the job on my grand prix right now. Google it for further explanation.

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


Still can be a cracked head gasket. Unless you are creating to much pressure in your engine. Just because you do not see any oil leaks does not mean that the head gasket could not be cracked

Oil in over coolant tank


If there is oil inside the coolant liquid that is the head gasket.

Check first if oil can leak into the coolant tank from the cap.

Usually when you get oil into the coolant liquid you have an head gasket problem, do a compression test, or buy the home tester below.
