Hi to All.
I've a '99 Camaro 3800 series II and today I've find a little bit of oil on the cap and the neck of the radiator.
Really 2 drops but are oil in the coolant(red).
I think it is motor oil because the color is the same and the coolant is red but I'm not shure.

Anyone can help me?


thanks!

looks like your antifreeze is old. cooling system needs to be flushed and new coolant. if you switch to green stuff youll need to flush a few extra times to get all the orange stuff out. also if your system is gunked up its good idea to flush heater core and radiator separately so you dont push gunk through the system.

 

ok craby but i have motor oil in coolant or do you think the coolant it' only very old?
I have to change the heads gaskets or the upper intake gasket?
what do you think?

thz

 

looks like coolant gunk. no way for oil to get into coolant, at least i dont think the 3.8 had an oil cooler, only way i know it can. head gasket or intake gasket failure will most times show coolant in the oil but can leak outside the engine and not get in the oil,,, or coolant.

 

do you have other reasons to believe you have a blown gasket in the engine?

 

Oil in the coolant is VERY rare in a push rod motor. There is no pressurized oil going through you head gasket. It is common in over head cam engines. If you did have it it would be due to a cracked block and you would be getting coolant in the oil as the motor cools down. I have never seen red motor oil, red transmission fluid but not motor oil.

The original coolant that came with the car is orange and be becomes a brownish mud color as it ages. You are probably the 30th person that has posted "I have oil in my coolant" and all of those where just old coolant. Getting all the bad stuff out can be a pain, You really should remove the radiator and dump it out while flushing it with a hose or search for a shop that has the flush equipment, most rad repair shops can flush your radiator without pulling it out.

 

no other reason.
my transmission oil is clear, my power steerling is clear, my motor oil is really very clear, my coolant have these dirty marks.

I think that these marks are engine oil but i don't know why in the engine oil there is no coolant.

Next week i channge and wash all the cooling system and i see in the marks appear again.
i thinks it is oil....

 

Gorn if the oil is not pressurized in the head gasket in what way it arrive up in the heads?

 

it just looks like oil ,do like what was said flush put new dexcool ,its gunk starting to form ,that looks just like oil ,an one can get a lot more then that at the bottom it could be a lot more that's why a flush gets some out ,you may seen it even after a flush ,no couse for alarm though
