fix soon or you will need a new engine.Motor oil in the radiator?
It may be residual or it may be a head gasket leaking into the cooling system. It may also be transmission fluid leaking from the oil cooler part of your radiator into the coolant and floating to the top. Inspect radiator but I also suggest this,





Have a small garage pressure test the cooling system (takes 2 minutes to do) to verify if the cooling system has a leak.





If it does confirm by examining all your spark plugs. The plug that is burning the coolant will look different from the other ones.





If you have a 4 cylinder accord the price is less expensive to have the head gasket replaced than if you had the V6 engine.





Once you have confirmed a failed head gasket budget up to $1000 for the repairs. Use only gaskets from Honda for the repair process but make sure it is the head gasket.





Once the job is done I suggest that the shop flush out the cooling system a few times to clean it of any leftover oil and refill with fresh ';Honda'; only premixed coolant. It is blue and insist on it from the dealer.
OOhhh this is not good. It means you have a way for oil to get into your cooling system. Which means you can get water in your oil. Water will not compress, therefore your engine will seize up and then you are talking BIG bucks. Get to a garage, your mechanic as soon as possible. It may just be a gasket, or it could be something worse. Don't wait, go to your mechanic. What ever it is it will require some disassembling of your engine.
Many radiators have oil coolers built in. Thats why the oil is in the radiator and not coolant in the oil. The oil is a t a higher pressure when the engine is running. Have it checked NOW. You may only have to replace radiator and oil change. Get a new thermostat at the same time. Good luck!!!
none of these people r right. u r all wrong. the radiator has cracked on the inside allowing tranny fluid in it. which means its in the tranny too. check the tranny dipstick, i bet it looks the same as inside the radiator. if so easy fix. new radiator, new tranny filter, and some fluid.
A cracked engine block! Is there any radiator fluid in the crank case as well? Check your oil, and if the oil is a light brown muddy color, then you've either got a cracked engine block, or a blown head gasket, or a cracked head.
blown head gasket, although usually the other way around( fluid in oil) depends on which motor you have, usual repair around 600-1000$
The usual cause of this is the head gasket is leaking. Only way out is to change the gasket as soon as possible.
Thats not good at all :( Sorry to be the bearer of bad news. Usually that means a blown head gasket which is very costly to repair.
Blown head gasket.





Can be expensive. I'd guess about 500 if the heads are not warped. 1000+ if the head has to be replaced.
Bad thing.





Front main seal is probably the culprit. Usually around $1000 or more to fix.
