Most likely a blown head gasket. Or if you own a GM it's probably the intake manifold gaskets. There is a class action law suit that has been settled , but getting any cash will be a chore. I have a 96 GMC and just changed them for the second time.
if there is engine oil in the antifreeze generally indicates a cracked head on the engine
You probably have a blown head gasket or a warped head
A leak somewhere, possibly cracked head or head gasket.
Antifreeze in the oil of any engine means there is a crack in the head gasket, or worse, in the block.
Could be a bad head gasket.
I have a 98 Malibu and I know from experience that antifreeze can leak from the intake gasket. It cost me $400 to fix it. At first we thought it was tranny fluid because it was pink, not that! I have Dexcool in my car and that is what was leaking from the intake. Common problem for the 3800 II; GMs` later 3800s have ALUMINUM intakes; I guess they found the problem, yet they didn`t choose to fix the other cars.....bastards...
vehicle will overheat. just dump the oil and antifreeze , flush engine and refill with clean oil
Antifreeze leak top of engine
HEadgasket failure, internal oil cooler leak.
A leak.
antifreeze leaking into the oil pan
hi
most likely a blown head gasket.
an oil leak
Failed gasket, seal, plug, cracked housing, etc.
There SHOULD only be oil inside the valve covers. If they leak coolant you have a serious problem.
The only reason is a leak. Usually small. The place to start is: If it smells like oil or antifreeze ...
Because it 's leaking- OIL, ANTIFREEZE, or vacume leak
cracked head or bad gasket
You may have blown a head gasket, check you oil to see if the antifreeze is leaking into there.
