Coco broke his first rule of troubleshooting..."check it out yourself, dont always count on "expert/dealer advice" to be correct...read on pls....
After much web searching i found that my 1992 acura 3.2L engine[C32A1] does have an engine oil cooler, located just below the water pump...My local acura dealers service mgr and "master mechanic" who found the oil in the coolant expansion tank indicated a head gasket problem[3 to 4 grand fix]. I quizzed them at the time whether it had an engine oil cooler, and its potential for leaking, and they "convinced" me that this engine "did not" have a engine oil cooler on it, so they ruled out potential for it to be leaking...and focused on to head gaskets...
....I must rule out the "oil cooler" leak befor tearing into the engine..ttfn
