yes, if you have coolant in the oil the oil doesn't give the rod bearings the lubrication that they need, they then overheat, and fail.
antifreeze leaks by the intake gasket into oil. deteriating bearings causing oil to leak by the bearing
Head gasket or cracked head. Mo
The system was overfilled and purged the excess coolant.
If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.
A small radiator leak can cause antifreeze to leak on your 1998 Chevy Lumina when there are not any spots on the ground. A pinhole in a hose can also cause this.
bad wheel bearing may cause it
Sounds like a rod bearing. Time for a rebuild job.
Check Antifreeze level..make sure there are no leaks under the vehicle.
No. All antifreeze types are not priced on quality but brand name. This should not have any bearing on your radiator leaking.
When antifreeze is poured into your oil, it weakens your oil cause it to break down prematurely and can cause your engine to fail by spinning an engine bearing and even smoke. This is also a sign of a blown head gasket.
You need to replace your intake manifold gasket. Chevy had a bad problem with these gaskets.
The ac compressor is shot. Usually what your hearing is a bearing that is moving around.
