97 2.0 with 110k on it
i bought this car a few weeks ago and it had been sitting not sure for how long. it started and ran decent idle a lil ruff but giving some gas and it cleaned up really good.. so i put some fresh gas in it and some sea foam fuel treatment for moisture in the tank and what not.. it did have a lil white smoke on exhaust!
once the fresh gas and the treatment got a chance to work hafter a few lil bit it cleaned up and ran better than ever.. however the check engine light came on.. and i then discovered oil in the radiator! no coolant in the engine oil tho?
help , ideas thoughts PLEASE

 

get the CEL scanned at autozone and let us know. But it sounds like a head gasket issue to me. Could also be the oil cooler

 

had a friend drive car in today while i was at work and got car scanned he said a few times at stop sign it idled a lil ruff but ran out just fine down road.
scann showed that #4 was lean either injector or somthing along thos lines
also i removed radiator cap and there are no bubbles or foam at all in the colant while running or just after you run it.. so is this just an oil cooler? and if so where are hte oil coolers located at this car?

 

Do you have an automatic or standard, if its an automatic, the radiator also cools the trans fluid, you might be looking at trans fluid and not oil, if that is the case replace the radiator, other than that I agree with TheEngineer
