Hello, some mates and I have been trying to start a 1985 110 2.5 Diesel that's been sat untouched for a few months. We went to squirt some easy start into the inlet manifold, but found that it was blowing air out. So much so that all of the easy start blew away. Can anybody suggest what might be causing this and advise how we can remedy it? Many thanks from all of us working on Big Car.
