I would tell you, both the 1.8 and 2.8 head gaskets really don't go that often. It seems that 9 times out of 10 it's an oil cooler when the coolant and oil mix. Mechanics often jump to that conclusion, and they're often wrong.

 

The problem has been solved, it was the oil cooler. Mechanic has by passed it and car now runs without one, has been running just fine past few days.
