Afraid of the answer.....

Actually this may be a good thing and I was half expecting this to happen.Remember the comment about the hose from the oil cooler? If the leak had been from the tank it would have meant replacing the tank. This would have cost several hundred dollars. I suspect that somehow the hose which blew apart may be connected to the wrong hose, possibly the drain hose. This might only require switching some hoses. Yes I know the hoses are different diameters and this should be unlikely but at this point anything is suspect and needs to be checked and confirmed.
You may have to do some feeling by hand or use a scope camera to confirm.
There are 3 hoses from the manifold to the tank. The hose in your pic on the left should attach to the top nipple of the manifold. This is the smallest diameter hose. This is the connection from the top of the oil cooler that the fitting broke on and should go to the purge valve. Of course the bottom hose on the manifold should be the drain hose.
Please follow the hose from the oil cooler, thru the broken fitting and to the top connection of the manifold.
It is probably easiest to determine that the drain hose goes to the bottom fitting. I believe you can see this from below.

I see JFP beat me to it while I was typing. Thanks!

Here is a picture of the manifold from inside the engine compartment.

The small diameter hose at the top is the oil cooler connection. The middle I believe is the vent from the radiators (not sure since I've never followed it). The lower that you can see just below the bend in the metal piping from the middle hose is the drain hose. Hope this helps.




And yes a pressure test would of course been the proper thing to do, but hell you've still got a full day and may resolve this yet!

I like this theory a lot and it's inexpensive!

I'm done for tonight, though.

Will be checking this board but not going to try any more work until tomorrow.

Thanks guys.

FYI The way I captured that image of the manifold was by using a camera held down behind the AOS, I think I had to move the shift cables out of the way until I found the correct angle.

The other thing I am going to try is disconnecting the quick release on the hose coming from the top of the oil cooler and then starting the car.

I'm going to need to flush and change the coolant anyway at this point.

This theory makes a lot of sense because somehow the overflow hose is being fed a steady stream of coolant.

I wonder what the flow rate from that hose from the oil cooler should be?

Also I'm going to see about procuring a pressure tester.

Inspector Clouseau will resume his work tomorrow.

Check your local auto parts stores, one may either rent or loan the tool.

The theory makes a lot of sense because the tank has been eliminated as the source of the coolant.

The source now has to be from the engine. Since the hose that failed was the oil cooler vent, This is the logical conclusion.

So if the hose from the oil cooler is connected to the overflow hose by mistake doesn't that mean that one of the other two hoses is also not connected properly or there is another hose that is not connected at all out of the 3 coming out of the overflow tank?

I really need an accurate diagram of these hoses and I don't have one.

Next investment is a Bentley Manual.
