If oil is geting in the coolant, you most likely have a leaking head gasket. there is one other item it could be if it has an automatic transmission, and that is the transmission cooler in the radiator, if the cooler is leaking it will allow transmission fluid to mix with the coolant.

I had my intake manifold gasket change along with the valve cover gasket. White smoke is still coming out of tailpipe?


White smoke may indicate an internal coolant leak or low coolant reservoir levels. Coolant leaks can also leak into the oil of your car causing it to be frothy or milky looking smoke. You might have a cracked head gasket, engine block, or cylinder head which are all caused by overheating.

first post is a viable option but i would do some diagnostic work first , check the OBDII codes as may be a sensor/switch that has overheated or got fried , check cylinder compressions to check for head gasket etc

Iv noticed oil in the coolant reservoir what could it be 02 trailblazer 4.2L any posible answers


depends on the type of oil in the reservoir!! Typical issues that will cause this on your 4.2L I-6 engine; 1. (usually pink/reddish oil) trans fluid leaking via faulty radiator, blown head gasket from overheating (severe), or someone accidentally added oil to your radiator!!

Have oil in my radiator fluid reservoir tank (1996 v6 3.8)


Twice in two years now my Saab 9-5 has had a pin-hole in the oil cooler, which has caused oil to flow into the reservoir. A way to tell is if coolant/oil is coming out of the reservoir cap. The reservoir cap is rated for the pressure of the coolant system, which is significantly lower than the oil pressure. When there is a hole in the oil cooler, oil will be forced out at relatively high pressures, causing the reservoir to fill and then over pressurize and spill out of the cap.

Blown head gasket. what is the cause? there is very high pressure in the radiator and eventually a lot of air and little coolant. it then starts over heating because all the coolant gets pushed out at the...


Running hot will cause head gasget to fail. Or if head is not torqued properly, or a faulty head gasget. Pressure in cooling system means, blown head gasget or cracked head.

This is typical of a bad head gasket. The gasket is shot, allowing the coolant to mix in w/ the oil.
