"HEY GRUMPYVETTE,
I went to check coolant levels and found oily slime floating in the radiator , it looks like oil but theres no coolant in my engine and the oil in the engine looks clean and I,m not smoking moisture out the exhaust?? so I don,t think its a cracked head or a head gasket.. any ideas??"
obviously, if you have coolant getting mixed with the oil theres a coolant leak into the engine, you could be dealing with a blown head gasket, leaking intake gasket, cracked cylinder head, cracked block, loose valve guide or other issues so you need to tear it down and locate the source of the coolant getting into your oil before it does major damage, which it will rather quickly
If you have an automatic transmission that uses the lower radiator as a transmission fluid cooler,its more than likely TRANSMISSION FLUID from an internal radiator leak if the trans cooler is in the lower radiator, check your trans fluid and the engine dipsticks for evidence.
obviously you'll need to find the source before things get real expensive,
btw thats not exactly rare in older corvette radiators in corvettes with automatic transmission and those cheap plastic tank radiators , and its a common factor in transmission failures, remember those lines pump hot trans fluid thru the radiator in a separate section
its usually tan or brown but it depends on the antifreeze its mixed with, and if your not seeing any coolant in the oil or trans fluid or moisture from the exhaust, or loosing coolant, (usually indications of a cracked head or blown head gasket,) it might just be oily crud that was in the radiator
think you may have a blown head gasket or cracked heads ETC??
have you tested for a cracked head or block with the reactive dye in the coolant that shows exhaust gasses contamination?
