The ECU was kicking into limp mode under heavy load and other things- but since the injectors were swapped maybe it won't do that anymore, as not all of the injectors worked. After the newest set of injectors were installed, it got hot on the test drive and blew the reservoir.

You know if I ran a shop I think I might just tell a owner of a vehicle I was working on look your coolant tank split a seam and is pouring out all it's life blood. Either they are incompetent or they are trying to cover up for being incompetent. I wonder which it is...

Edit: For additional info....

Consider that the customer didn't want any more billable hours on the car- to have it further examined would cost something... that's how this car has been from the start, and I didn't bill for the compression tests, fuel delivery tests or any of that.
If there's any other useful information you'd like- I'll give it to you if you ask for it, but my crystal ball is broken so I'm not sure what more information you are looking for. Explain low vacuum relating to coolant loss, please.

So now it just overheated but the tank isn't investigated. So I'm sure that I'm working my way to a ban from the mighty muddy oval...
