Liquid in Oil, Coolant Low...second Time in the Past 12 Months
About a year ago I took my 08 in for service, it had a large amount of milky oil on the fill cap, and noticeable milky substance on the dipstick. The dealer maintenance dept found the headgasket was cracked and replaced it. This was at 68,000 miles
20,000 miles and 11 months later I've got more buildup on the cap, milky oil on the dipstick, and my coolant is low. It isn't as bad as it was last year, but my powertrain warranty is up in May, or of course...100k. If this is a second headgasket replacement I'm going to get pretty nervous about what will happen 20,000 miles from now...the folks in the service department kept going on about condensation being a problem with the 2.2l Ecotec, but I drive 40 highway miles each way to work 5 days a week so that should have burned off what little condensation might build up.
Is there someone at GM I can talk to to try and squeeze some extra time out of for this issue specifically? Has anyone else had this problem with their Cobalt?
