Blow it up, burn it to the ground, take it to the dealer with a bottle of your favorite lube :rolleyes:




















































Or do a head gasket kit ;) :flipoff2:

It is the head gasket. Do you have water in the oil pan too. Often you will. Pull the plugs and see if it is going into one of the cylinders. One of the plugs will be Very clean and that will be the dead give away.

You neglected to inform us of what it is you are driving??
Automatic trans could be blown trans cooler in radiator?
Do you have an oil cooler built into your radiator?
Usually a blown head gasket wont put oil in the water, it would put water in the oil.
Could be a crack in a cylinder head or block where oil journal runs next to coolant passage.
Good luck....don't jump to any conclusions without doing a full diagnosis first!

Oil in the coolant could be from the rad tranny cooler, if it is an auto.
If not, you probably have a bad head gasket.
Be careful here, if antifreeze has gotten into the eng oil, it will eat the mains & rod bearings quickly. even worse than plain water.
Have the eng oil analysed for coolant. If it has gotten in the eng oil, I would suggest rolling in a set of bearings.

NAPA sells a kit to "block test" an engine, it is a chemical test. You fill a tube with a blue liquid, put over radiator opening, squeeze bulb and wait to see if liquid turns yellow, If it does, exhaust gases are present in cooling system. It's a pretty accurate test. You could always do a compression test to diagnose pressure readings in each cylinder to see which cylinder is leaking down. A radiator pressure test will tell you if you are leaking pressure, if you loose pressure and nothing hits the ground, you know it's going into the cylinder or block!
GOOD LUCK

each answer so far is possible but rember if it s a blown gasket...
and if uve been driving it have the head mag-nu-fluxed to check for cracks or warping..

has ur ride got hot?

if so then its probally the gasket maybe head...

and if uve been running it like this 9 chances out of 10 ur gonna have to replace rings .. which means a full block tear down usually..

so if this is the deal total rebuild.. build up..

or engine swap..
