I had similar problem on my 99 grand am. If you have oil in you coolant there is a chance your transmission cooler is leaking into your radiator. I had to replace intake and head gaskets several times, then I had coolant in my oil. Those 3400's are tough I put 240,000 on mine in 17 years, I would have put more but we have emissions testing and I couldn't get it to pass the last few years.
