Hi,

I've had my 2005 automatic roadster for 9 years and its been a fab car to own and drive. But unfortunately I now have a problem with it and any help or advice would be very much appreciated.

I recently noticed oil droplets (now increased to a layer of oil) in the radiator expansion tank. Can anyone tell me what might be the cause of this?

I've been told it might be the head gasket. Someone else said it might be the oil cooler but someone else said it doesn't have a oil cooler. Also where would be the best place to get oil cooler. (if it exists)

One last question - Where can I find original part numbers other than on the parts themselves?

Any thoughts or comments much appreciated
