sparky Paul Posted April 15, 2011 Report Posted April 15, 2011 If your compression figures are right, sounds like head gasket gone between 3 & 4. Quote

Not sure what they meant by 'special oil', the correct grade is 5W-30 regardless. Quote
seatkid Posted April 15, 2011 Report Posted April 15, 2011 (edited) No need for special oil on 2.3 engine. If youve just bought the car, it sounds as if they might have known it had a problem. If it was a car dealer then you should take the matter up with them. If it was a private sale, then see what they say. Edited April 15, 2011 by seatkid Quote
