Hello,
I am looking into buying a used 2005 aveo, 60 000km (37 300miles). I had it inspected and they performed a compression test that resulted in the following numbers :
#1 : 180
#2 : 180
#3 : 180
#4 : 110
They tried to locate the problem quickly by pouring some oil into the faulty cylinder, which helped the pressure go almost as high as the 3 other cyl. The conclusion was that it seems the compression ring has a slight problem.
So my question :
How problematic is that ? Is such a pressure difference common or not ? Is it likely to become a lot worse ? What could it result into ?
Thanks a lot for your help,
Pete, a potential aveo owner.
