Hi all, new to Aston Martin ownership.
purchased a 2007 vantage 4.3 with known engine issues. It’s been sitting in storage for 4yrs after an Aston dealer diagnosed it with worn rings. I’ve started doing my own diagnosis and after doing a compression test I’m suspecting a blown head gasket. One bank was fine ,all around 150 but the other is low. 100, 100, 75, 65 are the results. Anyone had any similar issues and think head gasket failure or something else.

cheers

 

A leak down test will tell you where the issue is
