Well we found the problem everyone has been talking about with the blue volvo, the bottom gasket is stuffed :(. Looks like the engine will have to come out.
We have two options at the moment:
1. we fix that motor and live with it
2. we get that beafier 2.3lt off Angus and shove that in

I took off the door and hopefully someone can tell us the trick to get these things in. We have the wrong set of books for this car all it says to do is:
Step 1. take door off
2. take clips off
3. take window out
4. put new window in, don't scratch it
5. put door on

it's shit, looks like we need the bentley brand of books
