my 01 v6 catera has lost about a half liter of coolant over a 2 month time span. (So little in fact, I only noticed it because the dummy dash light came on). A tiny puddle forms under the alternator, on top of oil pan. thought it was just a hose or something fairly simple, wanted to stave off the repair until spring=warmer weather.
But today while performing routine oil change, I notice some brownish/chocolate foamy condensation under oil filler cap?
Oil stream during change looked okay- just dark oil from 3K miles of driving
My work commute is an hour each way and the car shows no problems. Runs perfect- normal operating temperature, no oil loss, strong interior heat, no skipping, No CEL's.
The maintenance thread outlining head gasket repair procedure claims Head gaskets rarely fail on these hearty 6 cyl engines....and since the car runs perfect I'm keeping fingers crossed.
Could the coolant be mixing with oil? Could the car run perfect with that happening?
any thoughts or insights are greatly appreciated.
